Computes the device's orientation based on the rotation matrix. When it returns, the array values are as follows: values[0]: Azimuth, angle of rotation about the -z axis. This value represents the angle between the device's y axis and the magnetic north pole. When facing...
Sets the battery charge level of the selected virtual device. The value must range from 0% to 100%. This command forces the activation of the manual mode. battery getstatus Returns the current battery state of charge of the selected virtual device. ...
The properties describing a CameraDevice CameraDevice. These properties are primarily fixed for a given CameraDevice, and can be queried through the CameraManager CameraManager interface with CameraManager#getCameraCharacteristics.
