                    {
                        getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);

                    }

My code is as above, but when it call applyBatch() function it gives error as

"The method applyBatch(String, ArrayList<ContentProviderOperation>) is undefined for the type ContentResolver" How can I solve it?

That function is only available since API level 5 (which is Android 2.0). Either use a newer phone, or create an emulator for a newer api level. If you must use below api level 5 then working with contacts is a bit harder.
