It has been tested with the ScummVM core on:
- NVIDIA Shield TV running Android Nougat 7.0
- NVIDIA Shield Tablet running Android Nougat 7.0
- NVIDIA Shield Tablet running Android Lollipop 5.1
- Huawei Honor 7 running Android Marshmallow 6.0
- HTC Desire 500 running Android Jelly Bean 4.1
It's been tested using the touch screen, a USB mouse/keyboard combo, and a bluetooth mouse.
The Android version running on the device limits the functionality and user experience of the external mouse support.
Android Nougat and/or an NVIDIA SHIELD device with NVIDIA extensions provides the best user experience:

Android API < 24 and no NVIDIA extensions available:
- Both left and right mouse buttons supported
- The Android mouse cursor will be visible along with the in game mouse cursor

Description of how the the touchscreen mouse support works:
- You can move the in-game mouse cursor using the touch screen. The in-game mouse cursor will move relative to your movements on the touch screen, it will not be centered on where you press the screen.
- One quick tap on the touch screen results in the left mouse button being clicked
- Two taps on the screen and keeping the second tap pressed down results in a left mouse being held down until you release
- Two fingers on the touch screen results in the right mouse button being clicked
The touch screen mouse functionality is active at the same time as overlay support. This might cause some confusion when using cores that are designed for mouse support but where you have also enabled overlay controls. At the top of android_input.c there's a define that can be used to turn off this functionality if it causes more problems than it solves.
