What version of the Freepascal compiler are you using? Just wondering if the crash in the threaded code could be a problem with the Freepascal memory manager for Android 64-bit platform.

It is important for performance if your game is calling RefreshContent often on bitmaps or meshes that use Mesh/BitmapExpression. If you only use those expressions once during game init or level init then it won't matter.

Hard to say where the problem is now.

Try disabling threaded processing completely:

In TZApplication.Init insert this line

ZClasses.Tasks.Enabled := False;

Aha but wait: now you are testing with just a MeshExpression. A mesh expression needs a mesh to process. Try adding a MeshBox in front of it.

I suggest adding log lines in TMeshExpression.ProduceOutput until it can be shown where it crashes.

The error seems different now. I wish it was possible to get a callstack of the error.

What happens if you simply let Platform_GetCpuCount return 1? (so just a single line with "exit(1);")

Ok, I guess it is because MeshExpression tries to use threads.

Try this:

In Platform_GetCpuCount

change

CallStaticObjectMethodV(Env, RunClass, Mid, nil);

to

CallStaticObjectMethod(Env, RunClass, Mid);

Seems OpenGL doesn't load properly.

Does it still work to run a empty app with ClearColor set to red and it shows up red?

Please also post the full log without any lines removed.

There is a "Library found" message for bullet in the 64-bit log so at least it is getting to that point. I suggest you add a "Library loaded ok" log message on the line after dlopen so we can see if it finishes loading bullet lib before crashing. 09-12 12:23:28.875 E/ZgeAndroid(1...

Looks like bullet library crashes on initialization. I suggest you build bullet with debug info too.

Good . These change will improve the code quality for Android target. Thanks for not giving up.

Try changing that to

Yes indeed. The library is finally found! Now we can instead focus on what changes are required in ZExpression. The "TExpExternalFuncCall.Execute" code that you have enabled currently is designed for 32-bit. I think it would be better if you could make the Android 64-bit version use the bl...

Seems there is no ending slash in the path that Android reports:

Try this in the Java code:

.. nativeLibraryDir + "/";

It seems there is a different way to get the folder for native libs. https://stackoverflow.com/a/51020379/43673 Please try editing Zge.java. From: String libraryPath = getContext().getApplicationInfo().dataDir + "/lib/"; To String libraryPath = getApplicationInfo().nativeLibraryDir; If it ...
