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() {@Overridepublic 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;@Overridepublic void onCreate() {super.onCreate();mPlayer = MediaPlayer.create(this, R.raw.a);}@Overridepublic void onDestroy() {super.onDestroy();mPlayer.release();        stopSelf();}@Override@Deprecatedpublic void onStart(Intent intent, int startId) {// TODO Auto-generated method stubsuper.onStart(intent, startId);mPlayer.start();}@Overridepublic IBinder onBind(Intent intent) {return null;}}
