I am creating alarmmanager in one of my activities like following
AlarmManager alarmManager=(AlarmManager) MenuItems.this.getSystemService(Context.ALARM_SERVICE);
Intent intent23 = new Intent(MenuItems.this, MyReceiver.class);
PendingIntent pendingIntent23 = PendingIntent.getBroadcast(MenuItems.this, 0, intent, 0);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,System.currentTimeMillis(),300000,
pendingIntent);
After this i have following BroadcastReceiver
public class MyReceiver extends WakefulBroadcastReceiver
{
@Override
public void onReceive(Context context, Intent intent) {
ComponentName comp = new ComponentName(context.getPackageName(),
MyAlarmService.class.getName());
startWakefulService(context, (intent.setComponent(comp)));
setResultCode(Activity.RESULT_OK);
}
}
This broadcast receiver calls my following service
Public class MyAlarmService extends Service
{
private String server_response,data_to_send;
private String server ;
private String setLocation = "/xyz";
private URL url;
public double mLatitude;
private MainActivity main;
private boolean isGpsEnabled = false;
private sendToserver send;
private Context context;
public String vallatlong;
private boolean isNetworkEnabled = false;
private boolean canGetLocation = false;
private Location mLocation;

{
this.context = context;
getLocation();

Everything is working fine, my activity sets Alarmmanager which triggers broadcast-receiver after every 5 minutes which executes my service even when my app is closed and phone is not in use i am getting user location at my server, but on some phones like galaxy NoteEdge this code is not working. I am not getting user location after every 5 minutes am i doing something wrong. Please suggest any relevant way of doing this if this is not right way of doing.
