Tracker

Library for tracking network connection and understanding where do network anomalies occur.

How it works

The project has publisher-subscriber pattern: you subscribe, it gives you notifications.

Usage

Initialization

Class takes 2 required arguments: activity's context and period of refreshing dates.

private val context: Context = this 
val period: Long = 1000L 
val tracker:Tracker = Tracker(this, period) 

Activity flow

Subscribe after created, unsubscribe after destroyed.

class MainActivity(): AppCompatActivity() { 
  private val context: Context = this 
  val period: Long = 1000L 
  val t:Tracker = Tracker(context, period) 
  fun handleNetworkConnection(payload) { 
    print("I use payload", payload) 
  } 
  fun onCreate(){ 
    t.subscribe("Main Activity", TrackerEvent.NETWORK_CONNECTION, handleNetworkConnection) 
  } 
  ... 
  fun onDestroyed(){ 
     
    // stop checker, remove subscriber 
    t.stop() 
    t.unsubscribe(handleNetworkConnection) 
     
    // or use - stop checker and remove all subscribers 
    t.clean() 
  } 
} 

Pull logs

Function pullLogs gives you file with logs in ".txt", that you can send to back-end, cleanLogs - clean logs.

 ... 
 handleLogs () { 
   private val context: Context = this 
   val period: Long = 1000L 
   val t:Tracker = Tracker(context, period)     
    
   //heres also maybe your checks from back-end 
   val limit_logs = 100 
   if(t.countLogs() > limit_logs){ 
     val file: File = t.pullLogs() 
      
     //send on back-end somehow 
     ... 
      
     t.cleanLogs() 
   } 
 } 

Handle paralel activities

Use function changeNetwork() - the arg is class Payload.Network {activityName: String, dataUsage: Long}
