Libraries.android.view.InflateException:Binary XML file: Error inflating class android.view.View

Hello,

I am trying to wrap an Android native SDK into a Xamarin functionality. I have two .aar files, one depending of the other , which I bind each into two Android Binding projects. One of the binding project has a reference to the Dll created for the other .aar file. I'm a bit confused about the generated classes, but I still can call the public methods from somewhere else.

This is what I want to do actually. the code from the native SDK that I'm calling creates a new activity, inherited from AppCompatActivity which is trying to set a custom layout and start on the screen. When the methods from my Android App finishes, the device screen became blank and the app is throwing :
libraries.android.view.InflateException: Binary XML file line #1: Binary XML file line #1: Error inflating class android.view.View

This is the onCreate method which should be started. The worst part is that I'm not able to debug the SDK code (maybe someone know how to do that) , I can't find the call stack to see where is happening the error and no relevant info in the logs.

public void onCreate(Bundle paramBundle)
{
super.onCreate(paramBundle);

setFinishOnTouchOutside(false);

getWindow().addFlags(8192);

setContentView(R.layout.activity_myactivity);

this.e = new DeviceRotationManager(this, Rotation.NATIVE);

this.f = ((Toolbar)findViewById(R.id.toolbar));
setSupportActionBar(this.f);

....

What can be seen in the logs before crashing:
