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.
Input buffering is implicitly used by event accumulation, but this commit makes it more generic so it can be enabled for other uses.
For desktop OSs it's currently not feasible given main and UI threads are the same).
- API has been simplified: all events now go through `parse_input_event()`. Whether they are accumulated or not depends on the `use_accumulated_input` flag.
- Event accumulation is now thread-safe (it was not needed so far, but it prepares the ground for the following changes).
- Touch drag events now support accumulation.
* 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.
