Sony Xperia T (ST26) calendar account issue

Question

After factory reset of the device. I'm trying to retrieve the calendars display names(by the code below), it returns that there is no calendars. but when opening the device Calendar application at least one time, the default phone calendar will be retrieved correctly.

Is there any way to retrieve the calendars (especially the default ) without opening the device Calendar application?

Thanks in advance.

Here is the code for retrieving calendars exist on the device:

private Uri getCalendarUri() {
      return  Uri.parse(Integer.parseInt(Build.VERSION.SDK) > 7 ? "content://com.android.calendar/calendars" : "content://calendar/calendars");
   }

   private String[] getCalendars(Context context) {
      String[] res = null;
      ContentResolver contentResolver = context.getContentResolver();
      Cursor cursor = null;
      try {
         cursor = contentResolver.query( getCalendarUri(),
                 Integer.parseInt(Build.VERSION.SDK) > 13 ? new String[]{"_id", "calendar_displayName"} : new String[]{"_id", "displayName"}, null, null, "_id ASC");

         if (cursor.getCount() > 0) {
            res = new String[cursor.getCount()];
            int i = 0;
            while (cursor.moveToNext()) {
               res[i] = cursor.getString(0) + ": " + cursor.getString(1);
               i++;
            }
         }
      }
      catch (Exception e) {
         e.printStackTrace();
      }
      finally {
         if (cursor != null)
            cursor.close();
      }
      return res;
   }

I solved the issue.

using this code in my activity:

private static boolean calendar_opened = false;

private void openCalendar() {
  String[] calendars = getCalendars(this);
  if (!calendar_opened && calendars != null && calendars.length <= 0) {
     new Timer().schedule(new TimerTask() {
        @Override
        public void run() {
           runOnUiThread(new Runnable() {
              public void run() {
                 try {
                    //bring back my activity to foreground
                    final Intent tmpIntent = (Intent) MainScreen.this.getIntent().clone();
                    tmpIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
                    tmpIntent.setClass(MyExams.getInstance(), MainScreen.class);
                    PendingIntent.getActivity(MyExams.getInstance(), 0, tmpIntent, PendingIntent.FLAG_UPDATE_CURRENT).send();
                 }
                 catch (Exception e) {
                 }
              }
           });
        }
     }, 100 );//time is your dissection

     Intent i = new Intent();
     i.setClassName("com.android.calendar", "com.android.calendar.LaunchActivity");
     i.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
     startActivity(i);
     calendar_opened = true;
  }

}
//After my activity is on foreground I killed the calendar using this code, even there's no need because of FLAG_ACTIVITY_NO_HISTORY:
ActivityManager activityManager = (ActivityManager) MainScreen.this.getSystemService(Context.ACTIVITY_SERVICE);
activityManager.killBackgroundProcesses("com.android.calendar");

I think the device calendar application must be installing a calendar when you open it which may not be available before you open it after a factory reset.

I think you don't want the user to have to open the calendar application. If you don't mind the calendar application being opened in background, you could consider opening it through a Service an then closing it soon so that the user won't notice and the device calendar would be available.

thank you. but I don't want to interrupt user experience. Is it possible to close another application from my app/service? – naif.ult Dec 12 '12 at 16:09
Yes a service will NOT interrupt user experience because it's in background and since the control is still with your app, you can stop it too. So start it and then stop it soon. – adarsh Dec 12 '12 at 16:12
But opening the calendar application will! – naif.ult Dec 12 '12 at 16:17
A service launching the calendar application will only start it in the background I think and that will not be visible. User will still be on your application. – adarsh Dec 12 '12 at 16:18
It will be launched in foreground mode. – naif.ult Dec 12 '12 at 16:23

Thank you again. Working with Services is not the issue. But how to start the calendar application in background mode? – naif.ult Dec 12 '12 at 16:40
does that start in foreground too? – adarsh Dec 12 '12 at 16:46
Yes. it can be started in foreground. – naif.ult Dec 12 '12 at 16:59
Unless this starts in background, I wouldn't know how to start app in background mode. – adarsh Dec 12 '12 at 17:09
