Application won't start on Android with Qt 5.15

[vlada]

Hi,

I'd like to update from Qt 5.13.x to Qt 5.15, but my application won't start anymore with this release. I removed almost all Java code and external dependencies to identify the problem, but it still crashes right after start with these debug messages:

The Player.java code has been stripped to this:

import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
import org.qtproject.qt5.android.bindings.QtActivity;

public class Player extends QtActivity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        Log.d("Muzika", "onCreate: "+savedInstanceState);
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        Log.d("Muzika", "onDestroy, service bound: ");
    }

    public static void startPlayerService(Context ctx) {
        Log.d("Muzika", "Called start service, context: "+ctx);
        ctx.startService(new Intent(ctx, PlayerService.class));
    }
}

As you can see on the line 13, which is mentioned in the debug window, is the call to super.onCreate(savedInstanceState);

So the problem shouldn't be within my Java code.

I replaced the AndroidManifest.xml with a new one a copied the needed modifications back from my previous version. I'm now stuck and have no idea where to look further and how could I identify the root cause of the crash.

Do you have any idea? Thank you.

[ekkescorner]

so you replaced the Manifest - do you have recreated all the other stuff (gradle etc) from 'Create Templates' ?

[vlada]

Yes, I have used the "Create templates" button and just modified the AndroidManifest.xml to change name of my application, version etc.

@vlada I'm still on 5.13.2 yet. have to finish a customer project before jumping to 5.15 - so no idea what could be the difference in your case
