我已经创建了一个服务,而不是意图服务,因为我需要做一些异步工作(位置 服务器调用(,最后创建通知。
我首先有一个创建通知的广播员,仅此而已。效果很好。但是,在服务中,我启动了一个位置管理器,然后在回调中启动异步,然后在该回调中尝试创建通知,在抽屉中未显示!
这让我发疯。我尝试了您在代码中可以看到的吐司,这有效... 我真的很感谢您的帮助。
我的服务中的代码(简化为简短(,在所有功能正常,服务器,方法已记录等,但在抽屉中没有通知(仅当我直接从OnstartCommand调用清理(中没有通知(:
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
Log.d(TAG, "onStartCommand");
//.... doing various other stuff
handleAsyncStuff(session);
return START_STICKY;
}
....in my callback from final async server rest call:
private void cleanup(String header, String message){
try{
Log.d(TAG, "cleanup;header;" + header + ";message;" + message);
int duration = Toast.LENGTH_SHORT;
Toast toast = Toast.makeText(getApplicationContext(), message, duration);
toast.show();
Intent notificationIntent = new Intent(getApplicationContext(), MainTabActivity.class);
notificationIntent.putExtra(PreferencesHandler.INTENT_HEADER_PARAM, header); notificationIntent.putExtra(PreferencesHandler.INTENT_MESSAGE_PARAM, message);
final NotificationCompat.Builder builder = new NotificationCompat.Builder(getApplicationContext());
builder.setContentTitle(header)
.setAutoCancel(true)
.setWhen(System.currentTimeMillis())
.setContentText(message)
.setSmallIcon(R.drawable.notification)
.setAutoCancel(true)
.setDefaults(Notification.DEFAULT_ALL);
PendingIntent pendingIntent = PendingIntent.getActivity(GeofenceBackgroundService.this.getApplicationContext(),
NOTIFICATION_ID,
notificationIntent,
PendingIntent.FLAG_UPDATE_CURRENT);
builder.setContentIntent(pendingIntent);
Notification notification = builder.build();
NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
manager.notify(NOTIFICATION_ID, notification);
}finally{
//stopSelf(); Comment out did not make notification appear!
}
}
试试它,例如manager.notify( new andural((。nextint((,notification(;您必须每次传递不同的通知ID,否则它将被旧一个
