Android 12's Splash Screen API- Getting white screen after Splash Screen on some below Android 12 devices

Question

I have a dedicated SplashScreen Activity and on this activity, there is one API call (once in a lifetime), SDK initialization, setting default values for Firebase RemoteConfig, and routing logic. It's working fine as expected on some devices, but on some devices, I'm getting a white screen after displaying SplashScreen.

List of devices on which I did testing for it:

1. Samsung s20 fe (Android 12) - working as expected
2. OnePlus (Android 11) - working as expected
3. MI (Android 11) - getting a white screen
4. Moto G5 Plus (Android 8) - getting a white screen

Note: Above mentioned business logic doesn't take much time to get process, please check following logs

    @Override

    super.onCreate(savedInstanceState);
    splashScreen.setKeepOnScreenCondition(() -> true);

//at last calling nextScreen()
 private void nextScreen() {
        Timber.v("nextScreen");

        if (userLogin) {
            Timber.v("User details is not null in SplashScreen");
            showMainActivity();
        } else {
            Timber.w("User details is null in SplashScreen, opening LoginActivity");
            showLoginActivity();
        }
        finish();
    }

private void showMainActivity() {
    Intent intent = new Intent(SplashScreenActivity.this, MainActivity.class);
    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
    startActivity(intent);
}

Answer 1

This issue was about switching activity, so removing the following line of code for calling MainActivity will solve the problem.

intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
