Notifies the power manager that user activity happened.
[Android.Runtime.Register("userActivity", "(JZ)V", "GetUserActivity_JZHandler")]
public virtual void UserActivity (long when, bool noChangeLights);[<Android.Runtime.Register("userActivity", "(JZ)V", "GetUserActivity_JZHandler")>]
abstract member UserActivity : int64 * bool -> unit
override this.UserActivity : int64 * bool -> unitParameters
- when
- Int64
The time of the user activity, in the SystemClock#uptimeMillis()
time base. This timestamp is used to correctly order the user activity request with
other power management functions. It should be set
to the timestamp of the input event that caused the user activity.
- noChangeLights
- Boolean
If true, does not cause the keyboard backlight to turn on because of this event. This is set when the power key is pressed. We want the device to stay on while the button is down, but we're about to turn off the screen so we don't want the keyboard backlight to turn on again. Otherwise the lights flash on and then off and it looks weird.
