I'm seeing the following crashes on the variety of devices running Nougat according to Google Play Developer console. The issues seems to be occurred only on Android 7 but not all Android 7 users are affected. This crash occurs when launching activity.

-----AbstractBaseActivity.setupComponent----
private void setupComponent() {
AppComponentProvider provider = AppComponentProvider.class.cast(getApplication());
:
:
}
*xxApplication is implementing AppComponentProvider.
------------------------------------------------

-----AndroidManifest------
<application
android:name=".xxApplication"

I cannot reproduce this issue, and I don't understand why getApplication returns android.app.Application instead of my com.xxx.xxApplication.
It would be very helpful if you can figure this out, thanks.
