Here are the additional Android sensors:

Accelerometer sensor notes:
The accelerometer returns the current acceleration in SI meters per second squared. This measurement includes the force of gravity, so a device at rest will have an value of SDL_STANDARD_GRAVITY away from the center of the earth, which is a positive Y value.
values[0]: Acceleration on the x axisvalues[1]: Acceleration on the y axisvalues[2]: Acceleration on the z axisFor phones and tablets held in natural orientation and game controllers held in front of you, the axes are defined as follows:
The accelerometer axis data is not changed when the device is rotated.
Gyroscope sensor notes:
The gyroscope returns the current rate of rotation in radians per second. The rotation is positive in the counter-clockwise direction. That is, an observer looking from a positive location on one of the axes would see positive rotation on that axis when it appeared to be rotating counter-clockwise.
values[0]: Angular speed around the x axis (pitch)values[1]: Angular speed around the y axis (yaw)values[2]: Angular speed around the z axis (roll)For phones and tablets held in natural orientation and game controllers held in front of you, the axes are defined as follows:
The gyroscope axis data is not changed when the device is rotated.
This enum is available since SDL 3.2.0.
