[ANDROID] gamepad vibration

Description

The Gamepad wont vibrate even when the vibration support is enable.

For example the vibration wont working on the flycast core (this is core i tested).

I already consult with core creator flyinghead for flycast core and make a test.

To see whether the controller problem or not, I run the flycast standalone app, the controller vibrate on the standalone app but not in the core with retroarch.

I'm using Logitech F710 and Nvidia Shield Controller (2017)

Expected behavior

The gamepad vibrate with the vibration support enable.

Actual behavior

The gamepad is not vibrate with vibration support enable.

Steps to reproduce the bug

1. Open retroarch app
2. Settings > Input > Enable device vibration (for supported cores) -> set it to 'on'
3. Run flycast with dc games
4. On quick menu > option > pupuru vibration > set it to 'on'
5. on the game try to enable vibration support.

Version/Commit

You can find this information under Information/System Information

• RetroArch: 1.8.5 play store release

Environment information

• OS: Android 9

Start by reproducing the issue in the RetroArch Android app using the listed Settings > Input vibration option, the flycast core, and the Logitech F710 or Nvidia Shield Controller. Compare the Android app behavior with the flycast standalone app; done means supported gamepad vibration works in RetroArch with vibration enabled.
