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);
}
