Working with Call log

We often need to access call log details i.e. incoming number, outgoing number, missed call. We want to modify the call log i.e. make your own entry, deleting an existing entry. So let's see how can we do all this:

Uri UriCalls = Uri.parse("content://call_log/calls");

Cursor cursor = getApplicationContext().getContentResolver().query(UriCalls, null, null, null, null);

//Reading call log entries...

if(cursor.getCount() > 0){

    cursor.moveToFirst();

    while(!cursor.isAfterLast()){

        String number = cursor.getString(cursor.getColumnIndex(CallLog.Calls.NUMBER)); // for  number

        String name = cursor.getString(cursor.getColumnIndex(CallLog.Calls.CACHED_NAME));// for name

        String duration = cursor.getString(cursor.getColumnIndex(CallLog.Calls.DURATION));// for duration

        int type = Integer.parseInt(cursor.getString(cursor.getColumnIndex(CallLog.Calls.TYPE)));// for call type, Incoming or out going

        cursor.moveToNext();

    }

}

//Inserting values in call log...

ContentValues values = new ContentValues();

values.put(CallLog.Calls.NUMBER, number);

values.put(CallLog.Calls.CACHED_NAME, name);

values.put(CallLog.Calls.CACHED_NUMBER_LABEL, label);

values.put(CallLog.Calls.DATE, date);

values.put(CallLog.Calls.DURATION, duration);

values.put(CallLog.Calls.TYPE, myCallType);

getApplicationContext().getContentResolver().insert(CallLog.Calls.CONTENT_URI, values);

//Deleting entry in call log...

String queryString= "NUMBER='" + number + "'";

if (cursor.getCount() > 0){

        getApplicationContext().getContentResolver().delete(UriCalls, queryString, null);

}
