1. To obtain the battery information of the Android device, register a BroadCastReceiver whose Action is Intent. ACTION_BATTERY_CHANGED. 2. In the BroadcastReceiver onReceive () event, the received Intent. ACTION_BATTERY_CHANGED includes the following information: "Present" (boolean )..."Level" (int )... Remaining battery
Android Battery status monitoring If you want to monitor changes in the battery status, you need to dynamically register: android. intent. action. BATTERY_CHANGED: After receiving the Action, you can obtain the information you need based on the corresponding Key. For more information, see the BatteryChangedReceiver cla
