battery-Get phone battery information

If we want to get battery information for a cell phone, it can be broadcast. The system sends a broadcast when the battery level of the phone is changed. The specific code is as follows

// Register intentfilter.addaction (intent.action_battery_changed); Mcontext.registerreceiver (MHallReceiver, IntentFilter ); // Broadcast processing intent.getaction (). Equals (intent.action_battery_changed) {    int level = Intent.getintextra (" Level ", 0);        Manalogclockbattery.updatepercentage (level);}

That's all you can do.

Where level is the current amount of power, usually calculated as the total power 100来
