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));

ZGE does not use SDL on Android.

About the audio crash: if you try to play a sound do you hear this at all before it crashes?

I think Kjell contacted me with PM so it is possible the update was not mentioned on public forum. Sorry for the inconvenience.

For the Read beyond EOF issue: please try reimport the original model if you still have it.

MeshImport was updated earlier this year to handle different encoding options (in reply to Kjell having issues with .obj file import). Do you export to Android from the very latest ZGE? Please check to be sure: http://www.zgameeditor.org/files/ZGameEditor_beta.zip

Not sure if it matters but you could specify more debug options when compiling like this "-g -gl -gw"

Thread 20 "GLThread 731" received signal SIGSEGV, Segmentation fault. [Switching to Thread 9950.10745] When you see this, then it could be possible from gdb to get the callstack of the crashing thread (in this case thread 20). I've never used gdb but it seems getting the callstack is &quo...

Let's roll back a bit. Could there be problems with the size of the variables I changed in this commit ? Those changes look good so I don't think they are the problem. It seems it is possible to debug apps with jni native code from Android Studio: https://stackoverflow.com/questions/32413593/how-to...

Looks like a memory problem again. The vec3 memory is not initalized for some reason.
