Google calendar get events - events

Question

I am using this code and getting the events from the calendar and it is working fine but, I want to get the events from google accounts calendar .For example, I want to get the (deepakcando90#gmail.com )google calendar accounts events also? I know it is possible but do not know how to implement it?
public static void readCalendarEvent(Context context) throws ParseException {
ContentResolver contentResolver = context.getContentResolver();
Calendar calendar = Calendar.getInstance();
String dtstart = "dtstart";
String dtend = "dtend";
SimpleDateFormat displayFormatter = new SimpleDateFormat("EEEE, MMMM dd, yyyy");
stime=displayFormatter.format(calendar.getTime());
SimpleDateFormat startFormatter = new SimpleDateFormat("MM/dd/yy");
String dateString = startFormatter.format(calendar.getTime());
long after = calendar.getTimeInMillis();
SimpleDateFormat formatterr = new SimpleDateFormat("hh:mm:ss MM/dd/yy");
Calendar endOfDay = Calendar.getInstance();
Date dateCCC = formatterr.parse("47:59:59 " + dateString);
endOfDay.setTime(dateCCC);
cursor = contentResolver.query(Uri.parse("content://com.android.calendar/events"), (new String[] { "calendar_id", "title", "description", "dtstart", "dtend", "eventLocation" }), "(" + dtstart + ">" + after + " and " + dtend + "<" + endOfDay.getTimeInMillis() + ")", null, "dtstart ASC");
gCalendar = new ArrayList<GoogleCalendar>();
try {
System.out.println("Count=" + cursor.getCount());
if (cursor.getCount() > 0) {
System.out.println("the control is just inside of the cursor.count loop");
while (cursor.moveToNext()) {
GoogleCalendar googleCalendar = new GoogleCalendar();
gCalendar.add(googleCalendar);
int calendar_id = cursor.getInt(0);
googleCalendar.setCalendar_id(calendar_id);
String title = cursor.getString(1);
googleCalendar.setTitle(title);
String description = cursor.getString(2);
googleCalendar.setDescription(description);
String dtstart1 = cursor.getString(3);
googleCalendar.setDtstart(dtstart1);
String dtend1 = cursor.getString(4);
googleCalendar.setDtend(dtend1);
String eventlocation = cursor.getString(5);
googleCalendar.setEventlocation(eventlocation);
}
}
} catch (AssertionError ex) {
ex.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
}
}

You can try OAuth 2.0 service accounts to properly access the user accounts. Using a service account lets you impersonate users and perform operation on their behalf.
Accessing domain calendars as an app
An app can access domain-owned calendars without requiring user credentials if it authenticates using a service account. The service account must have the necessary access using domain-wide authority delegation. In order to impersonate a user account, specify the email address of the user account with the setServiceAccountUser method of the GoogleCredential factory.
I hope it helps. Goodluck :)
