I am trying to setup an Android MVPApp & have setup Dagger 2, butterknife successfully in my project & it is working with all activities on my device but still the android's firebase crashlytics is still showing several users with Android 19 & below version affected with the issue. Here's the stack trace from firebase console -

Here's the issue summary from firebase console -

enter image description here

The stacktrace suggests issue originated from MvpApp.java so here's the error source in line 55 -

Line 55

The stack trace suggests that the error is coming when it fails to inject dagger component to main app here - 

mApplicationComponent = DaggerApplicationComponent.builder()
                .applicationModule(new ApplicationModule(this)).build();

        mApplicationComponent.inject(this);

So, can anyone help me identify, debug or fix this issue.

I tried searching the issue around & found this -

Inject database in a ContentProvider with dagger

which has a suggested answer to move component initialization to attachbasecontext method instead of onCreate, I wanted to try this solution but I do not understand how to get instance of YourMainApplication

to call YourMainApplication.get(context).inject(this);

Log is not enough but, it seems like you have circular dependency injection. You could check injections on your classes.

For example 

public class A {
   @Inject 
   B classB; 

}

public class B {
   @Inject
   A classA; // this injection creates circular injection and also can cause stackoverflow exception
}

You must avoid this situation.
