I looked into the source code and found that the main module in qt bootstrap is named main_$(PREFERRED_ABI) instead of plain main. Also function WebView_AndroidGetJNIEnv is missing in qt bootstrap.
You can check my fix here XcantloadX@ed26a24 . Some changes are hard-coded because I don't know the correct way to implement it.
