使用Alarm Manager广播数据

Question

I am trying to send data to my parse SDK Database using Alarm Manager.

I am able to send data without Alarm manager.

My below code is not working correctly as parse sdk database is not showing updated data.

Here is my code:

Main Activity.java

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.create_todo);
        setTitle(R.string.create_todo);
        alarmMgr = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
        Intent intent = new Intent(this, AlarmReceiver.class);
        alarmIntent = PendingIntent.getBroadcast(this, 0, intent, 0);

        alarmMgr.setInexactRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP,
                AlarmManager.INTERVAL_FIFTEEN_MINUTES,
                AlarmManager.INTERVAL_FIFTEEN_MINUTES, alarmIntent);
}

AlarmReceiver.java

public class AlarmReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        MyAsyncTask asyncTask = new MyAsyncTask();
        asyncTask.execute(new String[]{});
    }


    class MyAsyncTask extends AsyncTask<String,Void,String>
    {

        @Override
        protected String doInBackground(String... params) {
            try {
                ParseObject parseObject = new ParseObject("Todo");
                parseObject.put("name", "abc");
                parseObject.save();
            }
            catch(ParseException e)
            {
            }
            return null;
        }
    }
}

Register your broadcast in AndroidManifest.xml file

Try below code:

alarm.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + AlarmManager.INTERVAL_FIFTEEN_MINUTES , AlarmManager.INTERVAL_FIFTEEN_MINUTES, pIntent); 

From above code, Below things will be happened.

first time Broadcast will be fired after 15 min. then it will be fired every 15 min.
