[置顶] Android代码广播检测手机电池

使用广播检测手机电池代码如下：

private static final String SYSTEMACTION_BATTERY_CHANGED = Intent.ACTION_BATTERY_CHANGED;

IntentFilter filter_system = new IntentFilter();
filter_system.addAction(SYSTEMACTION_BATTERY_CHANGED);
registerReceiver(systemReceiver, filter_system);

[BroadcastReceive方法代码]

private BroadcastReceiver systemReceiver = new BroadcastReceiver() {

		@Override
		public void onReceive(Context context, Intent intent) {
			if (intent.getAction().equals(SYSTEMACTION_BATTERY_CHANGED)) {
				int status = intent.getIntExtra("status", -1);
				boolean isCharging = status == BatteryManager.BATTERY_STATUS_CHARGING
						|| status == BatteryManager.BATTERY_STATUS_FULL;
				int chargePlug = intent.getIntExtra("plugged", -1);
				boolean usbCharge = chargePlug == BatteryManager.BATTERY_PLUGGED_USB;
				boolean acCharge = chargePlug == BatteryManager.BATTERY_PLUGGED_AC;
				if ((isCharging && usbCharge) || (isCharging && acCharge)) {
					Toast.makeText(context, "------", Toast.LENGTH_SHORT)
							.show();
					Intent intet = new Intent("com.charging.Broadcast.music");
					context.stopService(intet);
				} else {
					Intent intet = new Intent("com.charging.Broadcast.music");
					context.startService(intet);
				}
			}
		}
	};

[MusicService.java]

public class MusicService extends Service {
	private MediaPlayer mPlayer;

	@Override
	public void onCreate() {
		super.onCreate();
		mPlayer = MediaPlayer.create(this, R.raw.a);
	}

	@Override
	public void onDestroy() {
		super.onDestroy();
		mPlayer.release();
        stopSelf();
	}

	@Override
	@Deprecated
	public void onStart(Intent intent, int startId) {
		// TODO Auto-generated method stub
		super.onStart(intent, startId);
		mPlayer.start();
	}

	@Override
	public IBinder onBind(Intent intent) {
		return null;
	}

}
