Description Sven Gothel 2025-07-14 00:06:19 CEST 
Android 11 (SDK API 30): Package visibility in Android 11
- PackageManager.getApplicationInfo() fails with NameNotFoundException
- See <https://developer.android.com/training/package-visibility>
- Solution: Add query in users' apk or JogAmp AndroidLauncher `jogamp.android.launcher` manifest
  - See <https://developer.android.com/guide/topics/manifest/queries-element>

Android 11 (SDK API 30): Requires version min. request <= JNI_VERSION_1_6, JNI_VERSION_1_8 is rejected.
- In general, we can ask for a JNI_VERSION_1_6 min required version across all modules.

Android 14 (SDK API 34): Writable dex file is not allowed
- See <https://www.webviewgold.com/support-center/knowledgebase/solving-the-writable-dex-file-is-not-allowed-crash-in-android-apps/>
- Solution: Mark destination apk dex-file read-only

commit 35896e7984b8047282df474b76eadb20eb6bddda
    Android: Add android-stripped.jar (API 24) less java.* packages, avoiding collisions w/ Eclipse editor
Comment 3 Sven Gothel 2025-07-14 03:01:10 CEST 
commit 5400c3ce900b3be7472ff36b33ff7751686d2c1f
    Eclipse: Use android-stripped.jar in .classpath (via use library)
Comment 4 Sven Gothel 2025-07-21 13:46:30 CEST 
Android: Min API 24 -> 26
    
Desugaring w/ adding missing classes didn't work out well,
hence we are still in a Java 8 API situation within JogAmp
until using Android API 32 (Version 12) w/ full Java 11 support (?).
    
See <https://developer.android.com/build/jdks>
Comment 5 Sven Gothel 2025-08-25 04:31:51 CEST 
For a standalone Android bring-up test w/ demos (also included in the apk folder release/RC folder):

The fat demo APK jogl-demos-fat-android-${arch}.apk inside the jogl build folder can be directly installed and tested on your device w/ developer mode enabled.
