    text
    copied!<p>I have a tracking app that does tracking based on gps and cell id at every 2 minutes. I have started a service from MainActivity using setRepeting() of AlarmManager. Then inside that service I have written an asynctask.In onPreExecute() I fetch latitude and longitude using gps or cellid. And in doInBackground() i am fetching data from sqlite db and send to server. Even after writing all network related code in asynctask app sometimes says application not responding. and on pressing ok it restart. What can I do to avoid this.</p> <pre><code>public class SendDataAsync extends Service { Logger logger ; Context con; String level1; private BroadcastReceiver mBatInfoReceiver = new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { // Toast.makeText(getApplicationContext(),"in onReceive of GPSLoggerService", // Toast.LENGTH_LONG).show();
