我有一个已经被定义为一个服务如下Android的 - 活动的通知点击重新启动(该通知已被打开前台服务)
public class ForegroundService extends Service {
private static final String LOG_TAG = "ForegroundService";
@Override
public void onCreate() {
super.onCreate();
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
if(intent != null) {
if (intent.getAction().equals(Constants.ACTION.STARTFOREGROUND_ACTION)) {
Log.i(LOG_TAG, "Received Start Foreground Intent ");
Intent notificationIntent = new Intent(this, DashboardActivity.class);
notificationIntent.setAction(Constants.ACTION.MAIN_ACTION);
notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(getApplication(),
0,
notificationIntent,
PendingIntent.FLAG_NO_CREATE);
Intent previousIntent = new Intent(this, ForegroundService.class);
previousIntent.setAction(Constants.ACTION.PREV_ACTION);
PendingIntent ppreviousIntent = PendingIntent.getService(this, 0,
previousIntent, 0);
Intent playIntent = new Intent(this, ForegroundService.class);
playIntent.setAction(Constants.ACTION.PLAY_ACTION);
PendingIntent pplayIntent = PendingIntent.getService(this, 0,
playIntent, 0);
Intent nextIntent = new Intent(this, ForegroundService.class);
nextIntent.setAction(Constants.ACTION.NEXT_ACTION);
PendingIntent pnextIntent = PendingIntent.getService(this, 0,
nextIntent, 0);
Bitmap icon = BitmapFactory.decodeResource(getResources(),
R.drawable.art_background);
Notification notification = new NotificationCompat.Builder(this)
.setContentTitle("Truiton Music Player")
.setTicker("Truiton Music Player")
.setContentText("My Music")
.setSmallIcon(R.drawable.ic_launcher)
.setLargeIcon(
Bitmap.createScaledBitmap(icon, 128, 128, false))
.setContentIntent(pendingIntent)
.setOngoing(true)
.addAction(android.R.drawable.ic_media_previous,
"Previous", ppreviousIntent)
.addAction(android.R.drawable.ic_media_play, "Play",
pplayIntent)
.addAction(android.R.drawable.ic_media_next, "Next",
pnextIntent).build();
startForeground(Constants.NOTIFICATION_ID.FOREGROUND_SERVICE,
notification);
} else if (intent.getAction().equals(Constants.ACTION.PREV_ACTION)) {
Log.i(LOG_TAG, "Clicked Previous");
} else if (intent.getAction().equals(Constants.ACTION.PLAY_ACTION)) {
Log.i(LOG_TAG, "Clicked Play");
} else if (intent.getAction().equals(Constants.ACTION.NEXT_ACTION)) {
Log.i(LOG_TAG, "Clicked Next");
} else if (intent.getAction().equals(
Constants.ACTION.STOPFOREGROUND_ACTION)) {
Log.i(LOG_TAG, "Received Stop Foreground Intent");
stopForeground(true);
stopSelf();
}
}
return START_STICKY;
}
@Override
public void onDestroy() {
super.onDestroy();
Log.i(LOG_TAG, "In onDestroy");
}
@Override
public IBinder onBind(Intent intent) {
// Used only in case of bound services.
return null;
}
}
我已经定义在我的清单
android:launchMode="singleTask"
以下
而且
这是多么我开始服务
private void showNotificationService() {
Intent startIntent = new Intent(DashboardActivity.this, ForegroundService.class);
startIntent.setAction(Constants.ACTION.STARTFOREGROUND_ACTION);
startService(startIntent);
}
所以当我点击通知应用程序去onCreate,但我希望应用程序恢复到通知出现之前它是在什么状态。任何线索我做错了什么?
而且我使用这个博客前台服务提供的代码
