I think the Fpc devs are developing on Linux and Mac so they rarely test compiler building on Windows. Maybe the "fixes_3_2" branch works better to build? https://github.com/fpc/FPCSource/tree/fixes_3_2 The CheckSynchronize call is only needed if we use the Synchronize method but ZGE does ...

That version is from 2021 but I see that is the latest released version.

It would be good to test with latest trunk version. If you feel up for it, please check how to build Freepascal from source.

The log look normal to me.

It seems to boil down to that there is some general problem with Freepascal and threads on Android 64-bit.

Please remind me how you install the Freepascal compiler. Do you build it from source (if so from what branch) or do you use a prebuilt version?

The "2" parameter is the number of local Java handles needed. You can try raising it to 20. The nil in pop seems to be ok, it just indicates that we do not need a result. I'm not sure why simply calling BeginThread will causing things to fail. Do you still have cthreads as first unit in Zz...

Maybe we should try disabling more specific stuff. What happens if you comment out this line:

env^.CallNonvirtualIntMethodA(env, track, cAudioTrack, mWrite ..

Indeed, it seems you should always use the "A" version over the "V" version for 64-bit, I forgot that in the code I posted. While the game is running, the code will stay in the "while not AudioTerminated do" loop. So the "mRelease" part is for cleanup when the...

Try this change:

Code: Select all

      
      MixAndCopyData(PBuffer, Min(OnePassSize, bufferSizeInBytes));
      env^.ReleasePrimitiveArrayCritical(env, buffer, pBuffer, 0);
      env^.CallNonvirtualIntMethodV(env, track, cAudioTrack, mWrite, C([buffer, 0, Min(OnePassSize, bufferSizeInBytes)]));

Try adding this line as first line in C function:

Fillchar(Params, SizeOf(Params), 0);

Aha, sorry it should be "VPointer" and "PJValue".

I'm impressed with the solutions that ChatGPT suggest for you, they are better than expected.

Try this change:

Code: Select all

  Params : array[0..10] of JValue;

  function C(const args : array of const) : JValue;
  var
    I : integer;
  begin
     for I := 0 to High(args) do
       Params[I] := args[I].vtPointer;
     Result := @Params;
  end;

Try changing to NewObjectA.

Ok, let's keep trying and focus on jni.

1. Undo the changes to the two files that I suggested.
2. Then change the CallStaticIntMethodV to CallStaticIntMethodA like this:

Code: Select all

  bufferSizeInBytes := Env^.CallStaticIntMethodA(env, cAudioTrack, mGetMinBufferSize, C([AudioPlayer.AudioRate, 3, 2]));

Seems it is the "C" function that converts arguments that does not work on 64-bits.

Please try the attached changes to jni.pas and ZPlatform_Android.inc.

Also I just noticed the constant to choose stereo is 12 and not 2: https://developer.android.com/reference/android/media/AudioFormat#CHANNEL_OUT_STEREO So you could try changing 2 to 12 like this: bufferSizeInBytes := Env^.CallStaticIntMethodV(env, cAudioTrack, mGetMinBufferSize, C([AudioPlayer.Audi...

Try printing the bufferSizeInBytes value after it is assigned in ZPlatform_Android.

Platform_error('audio buffer size: ' + inttostr(bufferSizeInBytes));
