Constructors

BatteryManager()
BatteryManager(IntPtr, JniHandleOwnership)

A constructor used when creating managed representations of JNI objects; called by the runtime.

Fields

ActionCharging

Sent when the device's battery has started charging (or has reached full charge and the device is on power).

ActionDischarging

Sent when the device's battery may be discharging, so apps should avoid doing extraneous work that would cause it to discharge faster.
