VTM does not run on Android 15 with 16 KB page size

VTM does not run on 16 KB page size based Android 15.

It probably needs to rebuild the native libraries for Android.

Are you sure it doesn't work? For me it sounds like it's just an option to use 16 KB pages instead of 4 KB, but not a hard requirement.

@SammysHP

Set up the Android Emulator with a 16-KB-based, Android 15 system image and VTM does not work:
https://developer.android.com/guide/practices/page-sizes#16kb-emulator

(it works with regular Android 15 system image)

Even if it was compatible, I just found this notice:

We plan to make 16 KB page compatibility required for app uploads to the Google Play store next year.

I updated the process of building native libraries with #1126.

However, even if we build 16 KB-aligned native libraries with Android instructions,
it builds the same native libraries which do not run on Android 15 with 16 KB page size.

If someone knows better, you can try to build the native libraries:

• Set environment variable NDK_HOME
• Update ndk-build with Android instructions for 16 KB page size
• Run JniBuilder

Hi,
Can you tried to build JNI with gdx-jnigen 2.5.2 ?
libgdx/gdx-jnigen#73

I do not currently have a working environment for creating native libraries.

You could try building them and if they work correctly, I could merge them.
The instructions can be found above.
