android - fix issues other than the rendering (#5130)
# Objective - Make Bevy work on android ## Solution - Update android metadata and add a few more - Set the target sdk to 31 as it will soon (in august) be the minimum sdk level for play store - Remove the custom code to create an activity and use ndk-glue macro instead - Delay window creation event on android - Set the example with compatibility settings for wgpu. Those are needed for Bevy to work on my 2019 android tablet - Add a few details on how to debug in case of failures - Fix running the example on emulator. This was failing because of the name of the example Bevy still doesn't work on android with this, audio features need to be disabled because of an ndk-glue version mismatch: rodio depends on 0.6.2, winit on 0.5.2. You can test with: ``` cargo apk run --release --example android_example --no-default-features --features "bevy_winit,render" ```

### Debugging
|
||||
|
||||
You can view the logs with the following command:
|
||||
|
||||
```sh
|
||||
adb logcat | grep 'RustStdoutStderr\|bevy\|wgpu'
|
||||
```
|
||||
|
||||
In case of an error getting a GPU or setting it up, you can try settings logs of `wgpu_hal` to `DEBUG` to get more informations.
|
||||
|
||||
Sometimes, running the app complains about an unknown activity. This may be fixed by uninstalling the application:
|
||||
|
||||
```sh
|
||||
adb uninstall org.bevyengine.example
|
||||
```
