Implements per-pixel transparency feature on Android.
Allows plugins to do specific rendering and render godot UI on top
(useful for camera support with drawing on top).
This only adds support for a subset of Play Asset Delivery: this causes a single install-time asset pack to always be present, but doesn't add support for dynamically downloaded asset packs.
This is done by providing API access to app specific directories which don't have any limitations and allows us to bump the target sdk version to 30.
In addition, we're also bumping the min sdk version to 19 as version 18 is no longer supported by Google Play Services and only account of 0.3% of Android devices.
This was caused by the fact that a new instance of Godot was created at resume while a previous instance already existed.
The previous instance would then go through its cleanup lifecycle, and would thus attempt to close the entire app, leading to the system to restart the app, thus starting the cycle anew.
The fix involves reusing the previous instance of Godot if one is available instead of creating a new one, as well as giving control to the host activity for how the process should be terminated.
Aside from the cosmetic improvement of using the Godot-style type, this switches to acquire-release semantics, which may improve performance by not forcing a full barrier to be issued if the CPU architecture can use a cheaper one.
Key, touch and joystick events will be passed directly from the UI thread to Godot, so they can benefit from agile input flushing.
As another consequence of this new way of passing events, less Java object are created at runtime (`Runnable`), which is good since the garbage collector needs to run less.
`AndroidInputHandler` is introduced to have a smaller cross-thread surface. `main_loop_request_go_back()` is removed in favor just inline calling `notification()` on the `MainLoop` at the most caller's convenience.
Lastly, `get_mouse_position()` and `get_mouse_button_state()` now just call through `InputDefault` to avoid the need of sync of mouse data tracked on the UI thread.
* If not present, the dialog asks to load build sources from a file.
* The export templates check now also verifies that build sources are installed and skips the template check.
This makes Android development easier.
(cherry picked from commit 6639cc9853)
The `android:icon` attribute is expected to be the last one in the application
definition, as documented by the comment. cd64bcd missed that and caused some
arguments to be truncated.
Fixes#50224.
It can be turned off in the export preset with `package/classify_as_game`.
Upstream definition: https://developer.android.com/guide/topics/manifest/application-element#isGame
> `android:isGame`
>
> Whether or not the application is a game. The system may group together
> applications classifed as games or display them separately from other
> applications.
Also fixes replacing `android:allowBackup` in custom builds.
