+
+## 1. Configuration Issues
+
+### 1.1 Redirect URI Encoding Mismatch
+
+**Symptoms:**
+- "Redirect URI mismatch" error during authentication
+- Authentication fails with no clear error message
+- `MsalClientException` with error code `redirect_uri_validation_error`
+
+**Root Cause:**
+The signature hash in `auth_config.json` must be URL encoded, while the same hash in `AndroidManifest.xml` must NOT be URL encoded.
+
+**Solution:**
+
+```xml
+
+
+```
+
+```json
+// auth_config.json - MUST be URL encoded
+{
+ "redirect_uri": "msauth://your.package.name/ABcDeFg%2Bokk%3D"
+}
+```
+
+**URL Encoding Reference:**
+| Character | URL Encoded |
+|-----------|-------------|
+| `+` | `%2B` |
+| `=` | `%3D` |
+| `/` | `%2F` |
+| `*` | `%2A` |
+
+**Related Documentation:** [Configuration Guide](../../auth_config.template.json)
+
+---
+
+### 1.2 Missing or Incorrect Client ID
+
+**Symptoms:**
+- `MsalClientException: client_id` error
+- PCA initialization fails
+- "Application not found" error from Azure AD
+
+**Root Cause:**
+The `client_id` in `auth_config.json` doesn't match the Azure App Registration.
+
+**Solution:**
+1. Verify the Client ID in Azure Portal → App Registrations → Your App → Overview
+2. Update `auth_config.json`:
+```json
+{
+ "client_id": "YOUR_CORRECT_CLIENT_ID_FROM_AZURE_PORTAL"
+}
+```
+
+---
+
+### 1.3 Missing BrowserTabActivity in AndroidManifest.xml
+
+**Symptoms:**
+- Authentication starts but never completes
+- App doesn't receive the authentication response
+- Screen goes blank after entering credentials
+
+**Solution:**
+Add the BrowserTabActivity to your AndroidManifest.xml:
+
+```xml
+
+
+
+
+
+
+
+
+```
+
+---
+
+## 2. Authentication Errors
+
+### 2.1 AADSTS Error Codes
+
+**Common AADSTS Errors and Solutions:**
+
+| Error Code | Description | Solution |
+|------------|-------------|----------|
+| AADSTS50011 | Redirect URI mismatch | Verify redirect URI matches Azure App Registration exactly (including encoding) |
+| AADSTS50076 | MFA required | User needs to complete Multi-Factor Authentication |
+| AADSTS50079 | MFA enrollment required | User must enroll in MFA |
+| AADSTS65001 | Consent required | User or admin hasn't consented to the app |
+| AADSTS70002 | Invalid client secret | Update or regenerate client credentials |
+| AADSTS700016 | Application not found | Verify client_id is correct |
+| AADSTS90010 | Tenant not found | Verify tenant_id or use "common" for multi-tenant apps |
+
+**How to Find AADSTS Codes:**
+Enable verbose logging to capture the full error:
+```java
+Logger.getInstance().setLogLevel(Logger.LogLevel.VERBOSE);
+Logger.getInstance().setEnableLogcatLog(true);
+```
+
+---
+
+### 2.2 User Cancellation
+
+**Symptoms:**
+- `MsalUserCancelException` is thrown
+- Authentication callback receives cancellation error
+
+**Root Cause:**
+User pressed back button or dismissed the authentication prompt.
+
+**Solution:**
+Handle this gracefully in your callback:
+```java
+@Override
+public void onError(MsalException exception) {
+ if (exception instanceof MsalUserCancelException) {
+ // User cancelled - show appropriate message
+ showMessage("Sign in was cancelled");
+ return;
+ }
+ // Handle other errors
+}
+```
+
+---
+
+## 3. Token Acquisition Issues
+
+### 3.1 Deprecated API Usage
+
+**Symptoms:**
+- Compilation warnings about deprecated methods
+- Unexpected behavior or crashes
+- Token acquisition fails silently
+
+**Root Cause:**
+Using deprecated methods like:
+```java
+// ❌ DEPRECATED - DO NOT USE
+mPCA.acquireToken(activity, scopes, callback);
+mPCA.acquireTokenSilentAsync(scopes, account, authority, callback);
+```
+
+**Solution - Multiple Account Mode:**
+```java
+// ✅ CORRECT - Use Parameters-based API
+AcquireTokenParameters params = new AcquireTokenParameters.Builder()
+ .withScopes(Arrays.asList("User.Read"))
+ .withCallback(callback)
+ .build();
+mPCA.acquireToken(params);
+```
+
+**Solution - Single Account Mode:**
+```java
+// ✅ CORRECT - Use SignInParameters
+SignInParameters signInParams = new SignInParameters.Builder()
+ .startActivity(activity)
+ .withCallback(callback)
+ .build();
+mPCA.signIn(signInParams);
+```
+
+---
+
+### 3.2 Scope Format Errors
+
+**Symptoms:**
+- "Invalid scope" error
+- Token acquisition fails with scope validation error
+
+**Solution:**
+Ensure scopes are formatted correctly:
+```java
+// ✅ CORRECT
+List scopes = Arrays.asList("User.Read", "Mail.Read");
+
+// ❌ INCORRECT - Don't include resource prefix for MS Graph
+List scopes = Arrays.asList("https://graph.microsoft.com/User.Read");
+
+// ✅ CORRECT for custom APIs
+List scopes = Arrays.asList("api://YOUR_API_CLIENT_ID/access_as_user");
+```
+
+---
+
+## 4. Broker Integration Issues
+
+### 4.1 Broker Not Available
+
+**Symptoms:**
+- Authentication uses browser instead of Authenticator app
+- SSO doesn't work across apps
+- Error indicating broker is not available
+
+**Root Cause:**
+- Microsoft Authenticator, Company Portal, or Link To Windows not installed
+- `broker_redirect_uri_registered` set to `false`
+
+**Solution:**
+1. Ensure broker app is installed on the device
+2. Verify configuration:
+```json
+{
+ "broker_redirect_uri_registered": true
+}
+```
+
+---
+
+### 4.2 Broker Signature Mismatch
+
+**Symptoms:**
+- "Broker package signature verification failed"
+- Authentication falls back to browser
+
+**Root Cause:**
+The signature hash registered in Azure doesn't match the app's actual signing certificate.
+
+**Solution:**
+1. Get the correct signature hash:
+```bash
+keytool -exportcert -alias YOUR_KEY_ALIAS -keystore YOUR_KEYSTORE.jks | openssl sha1 -binary | openssl base64
+```
+2. Update Azure App Registration with the correct hash
+3. Update `auth_config.json` (URL encoded) and `AndroidManifest.xml` (not URL encoded)
+
+---
+
+## 5. Build and Dependency Issues
+
+### 5.1 AndroidX Compatibility
+
+**Symptoms:**
+- Build fails with duplicate class errors
+- "android.support" vs "androidx" conflicts
+- jetifier errors
+
+**Solution:**
+Ensure these properties are in `gradle.properties`:
+```properties
+android.useAndroidX=true
+android.enableJetifier=true
+```
+
+---
+
+### 5.2 MSAL Version Conflicts
+
+**Symptoms:**
+- Dependency resolution failures
+- Method not found errors at runtime
+- Missing class exceptions
+
+**Solution:**
+Use the latest MSAL version:
+```gradle
+dependencies {
+ implementation "com.microsoft.identity.client:msal:7.+"
+}
+```
+
+Ensure `minSdk` is at least 24:
+```gradle
+android {
+ defaultConfig {
+ minSdk 24
+ targetSdk 35
+ }
+}
+```
+
+---
+
+### 5.3 ProGuard/R8 Issues
+
+**Symptoms:**
+- App works in debug but crashes in release
+- ClassNotFoundException at runtime
+- Serialization/deserialization failures
+
+**Solution:**
+Add to your `proguard-rules.pro`:
+```proguard
+-keep class com.microsoft.identity.** { *; }
+-keep class com.nimbusds.** { *; }
+-dontwarn com.nimbusds.**
+```
+
+---
+
+## 6. Runtime Crashes
+
+### 6.1 PCA Not Initialized
+
+**Symptoms:**
+- NullPointerException when calling MSAL methods
+- App crashes on sign-in button click
+- "PublicClientApplication is null" error
+
+**Solution:**
+Always check PCA initialization before use:
+```java
+private void signIn() {
+ if (mPCA == null) {
+ Log.e(TAG, "PublicClientApplication not initialized");
+ showError("Authentication not ready. Please try again.");
+ return;
+ }
+ // Proceed with sign in
+}
+```
+
+Initialize PCA asynchronously:
+```java
+PublicClientApplication.createMultipleAccountPublicClientApplication(
+ context,
+ R.raw.auth_config,
+ new IPublicClientApplication.IMultipleAccountApplicationCreatedListener() {
+ @Override
+ public void onCreated(IMultipleAccountPublicClientApplication application) {
+ mPCA = application;
+ }
+
+ @Override
+ public void onError(MsalException exception) {
+ Log.e(TAG, "PCA creation failed: " + exception.getMessage());
+ }
+ }
+);
+```
+
+---
+
+### 6.2 UI Thread Violations
+
+**Symptoms:**
+- "Only the original thread that created a view hierarchy can touch its views"
+- CalledFromWrongThreadException
+- UI freezes or doesn't update
+
+**Solution:**
+Always update UI from the main thread:
+```java
+@Override
+public void onSuccess(IAuthenticationResult authenticationResult) {
+ activity.runOnUiThread(() -> {
+ updateUI(authenticationResult);
+ showMessage("Sign in successful!");
+ });
+}
+```
+
+---
+
+## 7. Single vs Multiple Account Mode Issues
+
+### 7.1 Wrong API for Account Mode
+
+**Symptoms:**
+- `MsalClientException: This method is not supported for multiple account mode`
+- `getCurrentAccount()` returns null in multiple account app
+- Sign in doesn't work as expected
+
+**Solution:**
+
+**Multiple Account Mode:**
+```java
+// ✅ Use for multiple account
+IMultipleAccountPublicClientApplication mPCA;
+mPCA.getAccounts(callback); // Get all accounts
+mPCA.acquireToken(params); // Sign in
+mPCA.removeAccount(account, callback); // Sign out specific account
+```
+
+**Single Account Mode:**
+```java
+// ✅ Use for single account
+ISingleAccountPublicClientApplication mPCA;
+mPCA.getCurrentAccount(callback); // Get current account
+mPCA.signIn(params); // Sign in
+mPCA.signOut(callback); // Sign out
+```
+
+---
+
+### 7.2 Account Mode Configuration Mismatch
+
+**Symptoms:**
+- Unexpected behavior after switching account modes
+- Account persistence issues
+
+**Solution:**
+Ensure `auth_config.json` matches your code:
+```json
+{
+ "account_mode": "MULTIPLE" // or "SINGLE"
+}
+```
+
+---
+
+## 8. Silent Token Refresh Issues
+
+### 8.1 Silent Token Acquisition Failure
+
+**Symptoms:**
+- `MsalUiRequiredException` thrown during silent acquisition
+- Token cache appears empty
+- User has to re-authenticate frequently
+
+**Root Cause:**
+- No cached token available
+- Refresh token expired
+- User consent required for new scopes
+
+**Solution:**
+Implement proper fallback to interactive authentication:
+```java
+AcquireTokenSilentParameters params = new AcquireTokenSilentParameters.Builder()
+ .withScopes(SCOPES)
+ .forAccount(account)
+ .withCallback(new SilentAuthenticationCallback() {
+ @Override
+ public void onSuccess(IAuthenticationResult result) {
+ // Use the token
+ }
+
+ @Override
+ public void onError(MsalException exception) {
+ if (exception instanceof MsalUiRequiredException) {
+ // Fall back to interactive
+ acquireTokenInteractively();
+ }
+ }
+ })
+ .build();
+mPCA.acquireTokenSilent(params);
+```
+
+---
+
+## Diagnostic Information to Request
+
+When an issue isn't covered above, ask the user for:
+
+1. **MSAL Version:** `implementation 'com.microsoft.identity.client:msal:X.X.X'`
+2. **Android Version:** Device API level and build number
+3. **Account Mode:** Single or Multiple
+4. **Broker Enabled:** Yes/No and which broker app

+If you've already followed that process, our security team will be in touch.
+
+For general security best practices with MSAL Android:
+- Always use the latest version of MSAL
+- Enable broker integration for enhanced security
+- Never log or store tokens in plain text
+- Use HTTPS for all network communications
+
+Thank you for helping keep MSAL Android secure!
+```
+

+
+### Out of Scope Response
+
+```markdown
+Thank you for reaching out! However, this issue appears to be related to [Azure AD / Microsoft Graph / Other Service] rather than the MSAL Android library itself.
+
+For assistance with this, please try:
+- **Azure AD Issues**: [Azure AD Support](https://azure.microsoft.com/support/)
+- **Microsoft Graph Issues**: [Microsoft Graph GitHub](https://github.com/microsoftgraph)
+- **General Azure Support**: Contact your Microsoft representative

+
+## Issue Triage Guidelines
+
+### Priority Levels
+
+| Priority | Criteria | Action |
+|----------|----------|--------|
+| P0 - Critical | Security vulnerability, data loss, complete breakage | Immediate escalation to team |
+| P1 - High | Production app blocked, major feature broken | Address within 24 hours |
+| P2 - Medium | Feature doesn't work as expected, workaround exists | Standard queue |
+| P3 - Low | Minor bug, cosmetic issue, enhancement | Backlog |
+
+### Issue Classification
+
+**Bug Reports** - Something isn't working correctly
+- Verify with reproduction steps
+- Check if it's a known issue
+- Determine if it's configuration vs. library issue
+
+**Feature Requests** - New functionality desired
+- Assess alignment with MSAL roadmap
+- Check if workaround exists
+- Add appropriate labels
+
+**Questions** - User needs guidance
+- Provide direct answer if possible
+- Link to relevant documentation
+- Consider if documentation should be updated
+
+**Security Issues** - Potential vulnerability
+- Redirect to security reporting process
+- Do not discuss details publicly
+- Escalate immediately if valid
+
+---
+
+## Escalation Procedures
+
+### When to Escalate
+
+1. **Security vulnerabilities** - Any confirmed security issue
+2. **Production-blocking issues** - Issues affecting released apps in production
+3. **Complex technical issues** - Problems requiring deep investigation
+4. **Repeated issues** - Same problem reported multiple times
+5. **Negative sentiment** - User is significantly frustrated
+
+### How to Escalate
+
+1. Add the appropriate priority label
+2. Tag the relevant team members
+3. Provide a summary of the issue and investigation so far
+4. Include all relevant logs and reproduction steps
+
+---
+
+## What NOT to Do
+
+### Never:
+
+1. **Share sensitive information**
+ - Don't post client IDs, secrets, or tokens
+ - Don't share internal discussion details
+ - Don't expose user PII
+
+2. **Make promises about timelines**
+ - Don't commit to specific fix dates
+ - Don't promise features will be added
+ - Use "we're investigating" rather than "we will fix"
+
+3. **Blame the user**
+ - Don't be condescending about mistakes
+ - Don't assume incompetence
+ - Frame feedback constructively
+
+4. **Ignore issues**
+ - Always acknowledge receipt
+ - Provide status updates
+ - Close with resolution or explanation
+
+5. **Discuss internal matters**
+ - Don't reference internal tickets by number
+ - Don't discuss team dynamics
+ - Keep focus on the technical issue
+
+6. **Provide incomplete solutions**
+ - Test code before sharing
+ - Verify documentation links work
+ - Ensure solutions follow current best practices
+
+---

+### 4.3 Broker Communication Failure on Android 15
+
+**Symptoms:**
+- `BrokerCommunicationException: Failed to get result from Broker Content Provider, cursor is null`
+- `android.accounts.AuthenticatorException: bind failure`
+- Error: `Failed to find provider info for com.azure.authenticator.microsoft.identity.broker`
+- Works on older Android versions but fails on Android 15
+
+**Root Cause:**
+Android 15 has stricter package visibility requirements that can prevent MSAL from communicating with the broker app (see GitHub issue #2232).
+
+**Solution:**
+1. Ensure Microsoft Authenticator is up to date
+2. Force stop and restart the Authenticator app
+3. If issue persists, clear Authenticator app data and re-add accounts
+4. Consider updating to the latest MSAL version which may have fixes for Android 15 compatibility
+
+---
+
+### 4.4 Broker Authentication Hangs or Gets Stuck
+
+**Symptoms:**
+- Authenticator app opens but spinner runs indefinitely
+- Authentication never completes after entering credentials
+- App hangs after broker is killed or force stopped
+- No callback received from broker
+
+**Root Cause:**
+When the Authenticator app is killed during authentication, MSAL may not receive a proper cancellation signal, leaving the interactive session stuck (see GitHub issues #1396, #1997).
+
+**Solution:**
+1. If stuck, restart both apps (yours and Authenticator)
+2. Implement a timeout for interactive authentication:
+```java
+// Add a reasonable timeout handler
+new Handler(Looper.getMainLooper()).postDelayed(() -> {
+ if (authenticationInProgress) {
+ showError("Authentication timed out. Please try again.");
+ authenticationInProgress = false;
+ }
+}, 120000); // 2 minute timeout
+```
+3. Update to the latest MSAL version which has improved broker handling

+
+### 4.5 Company Portal / Intune Integration Issues
+
+**Symptoms:**
+- Certificate-based authentication fails with Company Portal
+- Phone freezes when selecting certificates
+- "Company Portal isn't responding" message
+- Works in browser but not in Office apps
+
+**Root Cause:**
+Issues with Intune Company Portal's certificate storage or conditional access policies (see GitHub issue #2157).
+
+**Solution:**
+1. Update Company Portal to the latest version
+2. Re-enroll the device in Intune if problems persist
+3. Verify conditional access policies are correctly configured
+4. For certificate issues, ensure the certificate is properly installed in the work profile

+- R8 build fails with "Missing classes detected" error
+- Errors mentioning `edu.umd.cs.findbugs.annotations`, `com.google.crypto.tink`, or `net.jcip.annotations`
+
+**Root Cause:**
+MSAL has dependencies on optional classes that R8 cannot resolve during minification. This is a known recurring issue (see GitHub issues #1677, #2076, #2289, #2355).
**Solution:**
-Add to your `proguard-rules.pro`:

```
+For MSAL 6.0.0+ or 7.0.0+, you may also need:
+```gradle
+// Add Tink and SpotBugs annotations if R8 errors persist
+implementation("com.google.crypto.tink:tink:1.17.0") {

+### 5.4 display-mask Dependency Resolution
+
+**Symptoms:**
+- `Failed to resolve: com.microsoft.device.display:display-mask:0.3.0`
+- Build fails when adding MSAL dependency
+
+**Root Cause:**
+The `display-mask` library is hosted in a Microsoft-specific Maven repository that may not be included in your project's repository list (see GitHub issue #1027, #1720).
+
+**Solution:**
+Add the Microsoft Maven repository to your `settings.gradle`:
+```gradle
+dependencyResolutionManagement {
+ repositories {
+ google()
+ mavenCentral()
+ maven {
+ url 'https://pkgs.dev.azure.com/MicrosoftDeviceSDK/DuoSDK-Public/_packaging/Duo-SDK-Feed/maven/v1'

+### 6.3 Android 15 Edge-to-Edge Display Issues
+
+**Symptoms:**
+- Action bar overlaps content in the MSAL WebView on Android 15
+- Login form is partially unreadable
+- UI elements appear behind system bars
+
+**Root Cause:**
+Android 15 (SDK 35) enables edge-to-edge display by default, which affects MSAL's internal activities (see GitHub issues #2204, #2341).
+
+**Solution:**
+1. Update to the latest MSAL version which may include fixes
+2. If using custom themes, ensure proper insets handling:
+```xml
+
+```
+3. Consider using browser-based authentication (`authorization_user_agent: "BROWSER"`) as a workaround
+

+
+### 6.4 Fragment Transaction Errors
+
+**Symptoms:**
+- `IllegalStateException: FragmentManager is already executing transactions`
+- `No stored state. Unable to handle response`
+- Authentication spinner runs indefinitely when using `withFragment()`
+
+**Root Cause:**
+Using `withFragment()` in `AcquireTokenParameters` can cause issues with fragment lifecycle timing (see GitHub issue #1725).
+
+**Solution:**
+1. Avoid using `withFragment()` if possible - use `startAuthorizationFromActivity()` instead:
+```java
+// ✅ RECOMMENDED
+AcquireTokenParameters params = new AcquireTokenParameters.Builder()
+ .startAuthorizationFromActivity(requireActivity())
+ .withScopes(SCOPES)
+ .withCallback(callback)
+ .build();
+```
+
+2. If you must use `withFragment()`, ensure the fragment is fully resumed:
+```java
+@Override
+public void onResume() {
+ super.onResume();
+ // Only initiate authentication when fragment is fully ready
+ if (pendingAuthentication) {
+ startAuthentication();
+ }
+}
+```
+
+---
+
+### 6.5 ANR (Application Not Responding) Issues
+
+**Symptoms:**
+- App freezes during MSAL operations
+- ANR dialog appears
+- Main thread blocked waiting for lock
+
+**Root Cause:**
+MSAL performs network operations that can block the main thread if configuration or cloud discovery takes too long (see GitHub issue #1952).
+
+**Solution:**
+1. Never initialize PCA on the main thread during startup:
+```java
+// ❌ DON'T DO THIS
+@Override
+protected void onCreate(Bundle savedInstanceState) {
+ super.onCreate(savedInstanceState);
+ // This can cause ANR
+ mPCA = PublicClientApplication.createSingleAccountPublicClientApplication(this, R.raw.auth_config);
+}
+
+// ✅ DO THIS INSTEAD
+Executors.newSingleThreadExecutor().execute(() -> {
+ PublicClientApplication.createSingleAccountPublicClientApplication(
+ context,
+ R.raw.auth_config,
+ callback
+ );
+});

+### 8.2 AADB2C90080 - Expired Grant Error
+
+**Symptoms:**
+- `MsalUiRequiredException: AADB2C90080: The provided grant has expired`
+- Error occurs after refresh token expiry
+- User can log in interactively, but subsequent silent calls still fail
+- Error shows old token timestamps even after fresh interactive login
+
+**Root Cause:**
+This is a common B2C issue where the refresh token has expired due to sign-in frequency policies or token lifetime settings. After interactive login, stale cache entries may still be used (see GitHub issues #1004, #1216, #2043, #2257).
+
+**Solution:**
+1. Clear the account before re-authenticating:
+```java
+// When AADB2C90080 occurs, remove the account first
+mPCA.removeAccount(account, new IMultipleAccountPublicClientApplication.RemoveAccountCallback() {
+ @Override
+ public void onRemoved() {
+ // Now do interactive login
+ acquireTokenInteractively();
+ }
+
+ @Override
+ public void onError(MsalException exception) {
+ // Handle error
+ }
+});
+```
+
+2. For B2C, configure appropriate token lifetimes in Azure Portal
+3. Consider implementing proactive token refresh before expiration
+
+---
+
+### 8.3 No Cached Accounts Found
+
+**Symptoms:**
+- `MsalClientException: No cached accounts found for the supplied homeAccountId and clientId`
+- Silent authentication fails even though user previously signed in
+- Account list appears empty after app restart
+
+**Root Cause:**
+This can occur with B2C accounts, External ID tenants, or when there's a mismatch between the account's home tenant and the realm (see GitHub issues #1779, #2172).
+
+**Solution:**
+1. Verify you're using the correct account from `getAccounts()`:
+```java
+mPCA.getAccounts(new IPublicClientApplication.LoadAccountsCallback() {
+ @Override
+ public void onTaskCompleted(List accounts) {
+ if (accounts.isEmpty()) {
+ // No cached accounts, need interactive login
+ acquireTokenInteractively();
+ return;
+ }
+ // Find the right account for your policy/authority
+ for (IAccount account : accounts) {
+ if (accountMatchesPolicy(account)) {
+ acquireTokenSilently(account);
+ return;
+ }
+ }
+ }
+});
+```
+
+2. For B2C, ensure you're using the correct policy name and authority:
+```java
+AcquireTokenSilentParameters params = new AcquireTokenSilentParameters.Builder()
+ .fromAuthority(getAuthorityFromPolicyName("B2C_1_signin"))
+ .withScopes(scopes)
+ .forAccount(account)
+ .build();
+```
+
+---
+
+### 8.4 Silent Token Performance Issues
+
+**Symptoms:**
+- `acquireTokenSilent` takes 100-1000ms even when token is cached
+- Network calls made during cache lookup
+- Slow app startup due to token acquisition
+
+**Root Cause:**
+Silent token acquisition involves validation and potential network operations even when returning cached tokens (see GitHub issue #2097).
+
+**Solution:**
+1. Cache the access token in your app for immediate use
+2. Only call `acquireTokenSilent` when you need to refresh:
+```java
+// Check if your locally cached token is still valid
+if (localToken != null && !isTokenExpired(localToken)) {
+ useToken(localToken);
+ return;
+}
+
+// Only then call MSAL
+mPCA.acquireTokenSilent(params);
+```
+
+3. Use token expiration time to proactively refresh before expiry
+```

+## 9. Network and Cloud Discovery Issues
+
+### 9.1 Unable to Perform Cloud Discovery
+
+**Symptoms:**
+- `MsalClientException: Unable to perform cloud discovery`
+- `UnknownHostException: Unable to resolve host "login.microsoftonline.com"`
+- Authentication fails on certain network conditions
+
+**Root Cause:**
+This error occurs when MSAL cannot reach Microsoft's cloud discovery endpoints due to network issues, VPN configurations, proxy settings, or DNS problems (see GitHub issues #1568, #1765, #1696, #1723, #1663).
+
+**Solution:**
+1. Verify network connectivity to Microsoft endpoints:
+```java
+// Check network availability before MSAL calls
+ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
+NetworkInfo activeNetwork = cm.getActiveNetworkInfo();
+boolean isConnected = activeNetwork != null && activeNetwork.isConnectedOrConnecting();
+```
+
+2. For VPN/proxy environments:
+ - Ensure `login.microsoftonline.com` and `login.live.com` are accessible
+ - Configure proxy settings in the device's WiFi settings
+ - For emulators, ensure proper proxy configuration in Android Studio
+
+3. Handle cloud discovery failures gracefully:
+```java
+@Override
+public void onError(MsalException exception) {
+ if (exception.getMessage().contains("Unable to perform cloud discovery")) {
+ showError("Network connection required. Please check your internet connection.");
+ }
+}
+```
+
+---
+
+### 9.2 Power Optimization / Doze Mode Issues
+
+**Symptoms:**
+- `MsalClientException: Connection is not available to refresh token because power optimization is enabled`
+- Silent token refresh fails when device is in doze mode
+- Token refresh works when app is in foreground but fails in background
+
+**Root Cause:**
+Android's power optimization features (Doze mode, App Standby) restrict network access for apps running in the background (see GitHub issue #1766).
+
+**Solution:**
+1. Request exemption from battery optimization for critical apps:
+```java
+if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
+ PowerManager pm = (PowerManager) getSystemService(POWER_SERVICE);
+ if (!pm.isIgnoringBatteryOptimizations(getPackageName())) {
+ Intent intent = new Intent(Settings.ACTION_REQUEST_IGNORE_BATTERY_OPTIMIZATIONS);
+ intent.setData(Uri.parse("package:" + getPackageName()));
+ startActivity(intent);
+ }
+}
+```
+
+2. Perform token refresh when the app is in the foreground
+3. Cache tokens appropriately and refresh proactively before they expire
+
+---
+
+### 9.3 SSL/TLS Certificate Issues
+
+**Symptoms:**
+- `SSLHandshakeException: Chain validation failed`
+- `CertificateException: Chain validation failed`
+- "Response is unreliable: its validity interval is out-of-date"
+
+**Root Cause:**
+Device clock is incorrect, certificate chain is incomplete, or OCSP response has expired (see GitHub issue #1568).
+
+**Solution:**
+1. Verify device date/time is correct (automatic date/time should be enabled)
+2. For development, ensure you're not intercepting HTTPS traffic incorrectly
+3. Update to the latest MSAL version which includes updated certificate handling
+
+---
+
+## 10. WebView and Browser Issues
+
+### 10.1 Custom Tab / Browser Issues
+
+**Symptoms:**
+- "Chrome browser not found" error
+- Authentication fails with non-Chrome browsers
+- Login page doesn't open or crashes
+
+**Root Cause:**
+MSAL requires a compatible browser for authentication. Not all browsers support Custom Tabs correctly (see GitHub issues #1591, #1626, #1509).
+
+**Solution:**
+1. Add browser safelist to your `auth_config.json` if needed:
+```json
+{
+ "browser_safelist": [
+ {
+ "browser_package_name": "com.android.chrome",
+ "browser_signature_hashes": ["7fmduHKTdHHrlMvldlEqAIlSfii1tl35bxj1OXN5Ve8c4lU6URVu4xtSHc3BVZxS6WWJnxMDhIfQN0N0K2NDJg=="]
+ }
+ ]
+}
+```
+
+2. For devices without Chrome, consider using WebView mode:
+```json
+{
+ "authorization_user_agent": "WEBVIEW"
+}
+```
+
+**Note:** WebView mode does not support social identity provider logins (Google, Facebook). Use DEFAULT or BROWSER for those scenarios.
+
+---
+
+### 10.2 Authorization Flow Cancellation
+
+**Symptoms:**
+- `MsalClientException: Sdk cancelled the auth flow as the app launched a new interactive auth request`
+- `MsalClientException: Unable to complete authorization as there is no interactive call in progress`
+- Authentication fails when "Don't keep activities" is enabled
+
+**Root Cause:**
+Multiple simultaneous authentication requests, activity destruction during auth flow, or improper handling of auth state (see GitHub issues #1561, #1562).
+
+**Solution:**
+1. Track authentication state to prevent multiple simultaneous requests:
+```java
+private AtomicBoolean authenticationInProgress = new AtomicBoolean(false);
+
+public void signIn() {
+ if (!authenticationInProgress.compareAndSet(false, true)) {
+ Log.w(TAG, "Authentication already in progress");
+ return;
+ }
+
+ AcquireTokenParameters params = new AcquireTokenParameters.Builder()
+ .withCallback(new AuthenticationCallback() {
+ @Override
+ public void onSuccess(IAuthenticationResult result) {
+ authenticationInProgress.set(false);
+ // Handle success
+ }
+
+ @Override
+ public void onError(MsalException exception) {
+ authenticationInProgress.set(false);
+ // Handle error
+ }
+
+ @Override
+ public void onCancel() {
+ authenticationInProgress.set(false);
+ // Handle cancellation
+ }
+ })
+ .build();
+ mPCA.acquireToken(params);
+}
+```
+
+2. For "Don't keep activities" issues, use `singleTask` launch mode:
+```xml
+
+```
+
+---
+
+### 10.3 WebView SSO Issues
+
+**Symptoms:**
+- User has to re-authenticate in WebView after MSAL sign-in
+- SSO doesn't work between native MSAL and WebView content
+- Different sessions between MSAL and app WebViews
+
+**Root Cause:**
+MSAL and WebView use different cookie stores. The authentication session in MSAL is not automatically shared with app WebViews (see GitHub issue #1582).
+
+**Solution:**
+1. Use the access token from MSAL to authenticate API calls from WebView
+2. For web content requiring SSO, consider using the system browser instead of embedded WebView
+3. Pass authentication tokens to web content via URL parameters or headers (securely)
+
+---
+
+## 11. Azure AD B2C Specific Issues
+
+### 11.1 B2C Token Refresh Failures
+
+**Symptoms:**
+- `AADB2C90080: The provided grant has expired`
+- Silent token acquisition fails after some time
+- Works with interactive login but fails on subsequent silent calls
+
+**Root Cause:**
+B2C refresh tokens have different lifetime policies than standard Azure AD. Additionally, there can be cache mismatches between policies (see GitHub issues #1004, #1216, #2043, #2257, #1547).
+
+**Solution:**
+1. Clear the account before re-authenticating on refresh token expiry:
+```java
+@Override
+public void onError(MsalException exception) {
+ if (exception.getMessage().contains("AADB2C90080")) {
+ // Remove the account and force interactive login
+ mPCA.removeAccount(account, new RemoveAccountCallback() {
+ @Override
+ public void onRemoved() {
+ acquireTokenInteractively();
+ }
+
+ @Override
+ public void onError(MsalException e) {
+ // Handle error
+ }
+ });
+ }
+}
+```
+
+2. Configure appropriate token lifetimes in Azure B2C portal
+3. Match the authority URL exactly when acquiring tokens silently
+
+---
+
+### 11.2 B2C Policy Mismatch
+
+**Symptoms:**
+- "No cached accounts found for the supplied homeAccountId"
+- Account from one policy not found when using another
+- Silent acquisition fails even after successful interactive login
+
+**Root Cause:**
+B2C accounts are specific to the policy used during sign-in. Using a different policy or authority URL for silent acquisition will fail to find the cached account (see GitHub issues #1779, #1567, #1598).
+
+**Solution:**
+1. Match the policy name in silent token requests:
+```java
+// Helper to get the B2C policy from an account
+private String getB2CPolicyNameFromAccount(IAccount account) {
+ // Extract policy from account.getClaims() or account.getAuthority()
+}
+
+// Use matching authority for silent acquisition
+AcquireTokenSilentParameters params = new AcquireTokenSilentParameters.Builder()
+ .fromAuthority(getAuthorityFromPolicyName(policyName))
+ .withScopes(scopes)
+ .forAccount(account)
+ .build();
+```
+
+2. Store the policy name used during interactive login
+3. Search for accounts matching the desired policy before silent acquisition
+
+---
+
+### 11.3 B2C Custom Claims Issues
+
+**Symptoms:**
+- Claims null or missing after authentication
+- `account.getClaims()` returns null for federated users
+- ID token doesn't contain expected custom claims
+
+**Root Cause:**
+For B2C with federated identity providers, claims may not be returned if not configured in the user flow or custom policy (see GitHub issue #1491).
+
+**Solution:**
+1. Configure claims in Azure B2C user flow or custom policy
+2. Add required claims as application claims in B2C
+3. For federated users, ensure claims passthrough is configured
+4. Check both ID token and access token for claims:
+```java
+@Override
+public void onSuccess(IAuthenticationResult result) {
+ // Check ID token claims
+ Map claims = result.getAccount().getClaims();
+
+ // If claims are in access token, decode it
+ String accessToken = result.getAccessToken();
+ // Decode JWT to access claims
+}
+```

+- **Consultants** implementing solutions for clients
+
+### What NOT to Assume
+
+| Don't Assume | Instead |
+|--------------|---------|
+| User knows Azure AD internals | Explain authentication concepts clearly |
+| User has read all documentation | Provide relevant links and summaries |
+| User understands OAuth2/OIDC deeply | Explain token flows when relevant |
+| User has access to internal tools | Only reference public resources |
+| User is familiar with Microsoft terminology | Define terms like "broker," "claims," "scopes" |
+
+### Adjust Complexity Based on Context
+
+**For beginners:**
+- Provide step-by-step instructions
+- Include complete code examples
+- Explain the "why" behind recommendations
+- Link to getting-started guides
+
+**For experienced developers:**
+- Focus on the specific issue
+- Provide targeted solutions
+- Reference API documentation
+- Offer optimization suggestions
+
+### Key Vocabulary to Define
+
+When using these terms, include a brief explanation if context suggests the user may be unfamiliar:
+
+| Term | Plain Language Explanation |
+|------|---------------------------|
+| Broker | The Microsoft Authenticator app or Company Portal that handles sign-in securely |
+| Silent token acquisition | Getting a new access token without prompting the user to sign in |
+| Claims | Information about the user included in the token |
+| Scopes | Permissions your app is requesting |
+| Redirect URI | The URL Azure sends the user back to after sign-in |
+| PCA | Public Client Application - the main MSAL object for mobile apps |

4. **Set expectations** - Be clear about what can and cannot be done
5. **Follow up** - Check back if you've asked for information
+### Language and Tone Guidelines
+
+**Be Novice-Friendly:**
+- Avoid technical jargon unless absolutely necessary
+- When technical terms are needed, provide simple explanations
+- Use everyday language that anyone can understand
+- Don't assume familiarity with OAuth, Azure AD, or authentication concepts
+
+**Make Information Digestible:**
+- Break complex answers into numbered steps
+- Use bullet points for lists of options or requirements
+- Start with the most important information first
+- Keep paragraphs short (2-3 sentences maximum)
+- Use headers and formatting to organize longer responses
+
+**Answer Questions Completely:**
+- Read the entire question before responding
+- Address every part of multi-part questions
+- If you're unsure about part of the question, acknowledge it and ask for clarification
+- Summarize what you understood if the question is complex
+
+**Show Respect:**
+- Treat every question as valid, no matter how basic it seems
+- Never use language that could be perceived as condescending
+- Acknowledge the user's efforts and frustrations
+- Use phrases like "Great question!" or "That's a common scenario" to validate their concerns
+
+**Example - Too Technical:**
+> "The AADSTS50011 error indicates a redirect URI mismatch between your auth_config.json and the Azure Portal app registration's reply URLs. Ensure URL encoding of the signature hash in the redirect_uri parameter."
+
+**Example - Novice-Friendly:**
+> "This error means that the 'redirect address' in your app doesn't match what's registered in Azure. Think of it like a mailing address — if the return address on your letter doesn't match, the post office can't deliver it back to you.
+>
+> Here's how to fix it:
+> 1. Open your Azure Portal and find your app registration
+> 2. Check the 'Redirect URIs' section
+> 3. Make sure it exactly matches what's in your app's config file
+>
+> Need help finding these settings? Let me know and I can walk you through it step by step."
