Android 10 Activity onCreate Crash

Question

The splash activity of my app works well on all devices except on an Android 10 device that I have just recently updated.

Here is my code:

public class SplashScreen extends AppCompatActivity {
  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    if(FirebaseAuth.getInstance().getUid() != null)
      startActivity(new Intent(this, HomeActivity.class));
    else
      startActivity(new Intent(this, LoginActivity.class));

    finish();
  }

}

I have also tried navigating directly to HomeActiviy or LoginActivity but still crashes when I try to run on an Android 10 device

Error occurs when calling super.onCreate(savedInstanceState)

Has anyone able to fix this issue?

There is some issue in ReportFragment. Please check or debug — Jaymin, Jan 17 '20 at 06:21
Can you add the dependencies in build.gradle(app) with your question? The problem may be due to the new androidx library — Pankaj Sati, Jan 17 '20 at 06:26

As per this issue, this will occur when using lifecycle-runtime:2.2.0 (usually through a transitive dependency on Fragment or AppCompat) and lifecycle-process:2.1.0 (usually through a transitive dependency on lifecycle-extensions).

There are a number of work arounds available in the bug:

You do any one of the following:

Add an explicit dependency on lifecycle-process:2.2.0-alpha05 to pull in the new version that is compatible with lifecycle-runtime:2.2.0-alpha05

Upgrade your lifecycle:extensions dependency to 2.2.0-alpha05 so that lifecycle-process is upgraded

Remove the lifecycle:extensions dependency entirely and use only the lifecycle libraries you need (for example, use lifecycle-viewmodel-ktx if you want ViewModels) so that you don't pull in lifecycle-process at all

Or, since the compatibility issue has been fixed in a later release, upgrade to a later version of Fragments (version 1.2.0-beta01 or higher) or Lifecycle 2.2.0-beta01 or higher if you directly depend on Lifecycle.

This helped me to solve my issue, so I updated my app gradle from androidx.lifecycle:lifecycle-runtime:2.2.0-alpha05 to the latest version androidx.lifecycle:lifecycle-runtime:2.2.0-rc03 and that's it — Rick Royd Aban, Jan 17 '20 at 06:36
