Firebase, Digits Authentication Error, Activity Destroyed issue

Question

I am trying to login via Firebase and facing a weird issue. I can successfully login on all devices except some Samsung devices. While Debugging I found issue at:

    }

    @Override
    public void onStart() {
        super.onStart();
        mAuth.addAuthStateListener(mAuthListener);
    }

    @Override

        super.onStop();

        this.screenTag = R.string.tag_home;
         startMainActivity(screenTag, user);

    }

    @Override
    public void failure(DigitsException error) {
        error.printStackTrace();
    }
}

It throws error as below:

I am not switching any fragment, it is a simple activity. I am confirming mobile number via Twitter Digits sdk prior to login. It works fine. I get crash only once right after confirmation via Digits. Relaunching app that does not send Digits confirmation runs smooth.

I wonder if Digits is doing some trouble with that. While debugging I have found that Twitter Digits startPhoneNumberActivity with flags Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TOP Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TOP . What I assume these flags are destroying previous activity.

I have already tried following with this activity but no use:

android:persistent="true"
android:noHistory="false"

Answer 1

FLAG_ACTIVITY_CLEAR_TOP is the problem here which kills the activity.

calling the Fabric.with(this, new TwitterCore(authConfig), new Digits()); in the onCreate() activity method can solve the problem for you.
