我在forever循环中有一项服务,但随着时间的流逝,它要么死掉,要么循环结束.我已经有一段时间了,任何建议或建议都将不胜感激.谢谢！

这是启动服务的方式

Intent myIntent = new Intent(this, MyService.class);               pendingIntent = PendingIntent.getService(this, 0, myIntent, 0);                 AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);                 Calendar calendar = Calendar.getInstance();                 calendar.setTimeInMillis(System.currentTimeMillis());                 calendar.add(Calendar.SECOND, 10);                 alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent);

这是该服务的Onstart命令

@OverrIDe    public int onStartCommand(Intent intent, int flags, int startID)     {     try{            //Toast.makeText(getApplicationContext(), " Service Started", Toast.LENGTH_LONG).show();                    @SuppressWarnings({ "rawtypes", "unchecked" })                    AsyncTask<VoID, VoID, VoID> asyncTask = new AsyncTask() {                            @OverrIDe                            protected voID onPreExecute() {                            }                            @OverrIDe                            protected VoID doInBackground(Object... objects) {                                //Get Username from sql not static value.

解决方法:

您的服务不是前台服务,因此可以随时将其终止.您可以使用Service.startForeground解决问题.您也可以通过从onStartCommand返回START_REDELIVER_INTENT进行修复,然后它将以相同的意图再次调用您的服务.请查阅文档的this part,以获取有关服务生命周期的更多信息.
