Getting events from calendar

That code above is pretty awful (and it does not seem to work in ICS - definitely the column names are different)

The page here: http://developer.android.com/guide/topics/providers/calendar-provider.html

provides a much better overview. A (much) simpler code to retrieve calendars:

public class CalendarContentResolver {
    public static final String[] FIELDS = { 
        CalendarContract.Calendars.NAME,
        CalendarContract.Calendars.CALENDAR_DISPLAY_NAME,
        CalendarContract.Calendars.CALENDAR_COLOR,
        CalendarContract.Calendars.VISIBLE 
    };

    public static final Uri CALENDAR_URI = Uri.parse("content://com.android.calendar/calendars");

    ContentResolver contentResolver;
    Set<String> calendars = new HashSet<String>();

    public  CalendarContentResolver(Context ctx) {
        contentResolver = ctx.getContentResolver();
    }

    public Set<String> getCalendars() {
        // Fetch a list of all calendars sync'd with the device and their display names
        Cursor cursor = contentResolver.query(CALENDAR_URI, FIELDS, null, null, null);

        try {
            if (cursor.getCount() > 0) {
                while (cursor.moveToNext()) {
                    String name = cursor.getString(0);
                    String displayName = cursor.getString(1);
                    // This is actually a better pattern:
                    String color = cursor.getString(cursor.getColumnIndex(CalendarContract.Calendars.CALENDAR_COLOR));
                    Boolean selected = !cursor.getString(3).equals("0");
                    calendars.add(displayName);  
                }
            }
        } catch (AssertionError ex) { /*TODO: log exception and bail*/ }

        return calendars;
    }
}

Hope this helps!

Ok i found the answer of this whole of the concept that how to use the google calendar application integration with the android phone.

code:--

first you set this line which will goes to read the calendar events form the other class form your class which is current is the ApplicationSettings.java .

ReadCalendar.readCalendar(ApplicationSettings.this);

package com.mycalendarevents.android;

import java.util.Date;
import java.util.HashSet;
import java.util.regex.Pattern;

import android.content.ContentResolver;
import android.content.ContentUris;
import android.content.Context;
import android.database.Cursor;
import android.net.Uri;
import android.text.format.DateUtils;

public class ReadCalendar
{
    static Cursor cursor;

    public static void readCalendar(Context context) {

        ContentResolver contentResolver = context.getContentResolver();

        // Fetch a list of all calendars synced with the device, their display names and whether the

        cursor = contentResolver.query(Uri.parse("content://com.android.calendar/calendars"),
                (new String[] { "_id", "displayName", "selected"}), null, null, null);

        HashSet<String> calendarIds = new HashSet<String>();

        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()) {

                    String _id = cursor.getString(0);
                    String displayName = cursor.getString(1);
                    Boolean selected = !cursor.getString(2).equals("0");

                    System.out.println("Id: " + _id + " Display Name: " + displayName + " Selected: " + selected);
                    calendarIds.add(_id);
                }
            }
        }
        catch(AssertionError ex)
        {
            ex.prin
