I have an Android QT app with more than has 14K active users at the moment of writing this post. The app is relatively stable, its crash rate is 0.34%:
but there is a specific user with Xiaomi Redmi 3 (ido), Android 5.1 that cannot even run the app on his device. When he starts the app, a white screen is displayed and then the app crashes. Google Play Console reports that he attempted to start the app 7 times, but with no success:
The backtrace is
*** *** *** *** *** *** *** *** *** *** *** *** *** *** *** ***
pid: 0, tid: 0 >>> net.geographx.LinesGame <<<

QT version I build the app with is 5.13.0.

I fixed this by moving MobileAds.initialize call before super.onCreate in my Android activity:
public class MainActivity extends org.qtproject.qt5.android.bindings.QtActivity
{
...
@Override
public void onCreate(android.os.Bundle savedInstanceState)
{
Log.d(TAG, "In the onCreate() event");
boolean available = isGooglePlayServicesAvailable();
if (available)
{
Log.d(TAG, "Initializing the Mobile Ads SDK...");
com.google.android.gms.ads.MobileAds.initialize(this);
}
else
{
Log.d(TAG, "Google Play Services are not Available");
}
super.onCreate(savedInstanceState);
if (available)
{
Log.d(TAG, "Creating InterstitialAd...");
// Create the InterstitialAd and set the adUnitId.
iAd = new com.google.android.gms.ads.InterstitialAd(this);
iAd.setAdUnitId(AD_UNIT_ID);
}
}
...
}
