" All Day: " + allDay);
}
}

i got null-pointerException.
The folder you're looking for is at /data/data/com. android. calendar/ but the stuff you need is under /data/data/com.
Add the widget to your home screenSearch for the Google Calendar app and tap it. To customize your widget size, swipe left. Tap Add widget. In the top right, tap Done.
My problem solved and i use below code
-
public class Utility {
public static ArrayList<String> nameOfEvent = new ArrayList<String>();
public static ArrayList<String> startDates = new ArrayList<String>();
public static ArrayList<String> endDates = new ArrayList<String>();
public static ArrayList<String> descriptions = new ArrayList<String>();
public static ArrayList<String> readCalendarEvent(Context context) {
Cursor cursor = context.getContentResolver()
.query(
Uri.parse("content://com.android.calendar/events"),
new String[] { "calendar_id", "title", "description",
"dtstart", "dtend", "eventLocation" }, null,
null, null);
cursor.moveToFirst();
// fetching calendars name
String CNames[] = new String[cursor.getCount()];
// fetching calendars id
nameOfEvent.clear();
startDates.clear();
endDates.clear();
descriptions.clear();
for (int i = 0; i < CNames.length; i++) {
nameOfEvent.add(cursor.getString(1));
startDates.add(getDate(Long.parseLong(cursor.getString(3))));
endDates.add(getDate(Long.parseLong(cursor.getString(4))));
descriptions.add(cursor.getString(2));
CNames[i] = cursor.getString(1);
cursor.moveToNext();
}
return nameOfEvent;
}
public static String getDate(long milliSeconds) {
SimpleDateFormat formatter = new SimpleDateFormat(
"dd/MM/yyyy hh:mm:ss a");
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(milliSeconds);
return formatter.format(calendar.getTime());
}
