How to set a ringtone through code in android?

To set any audio file as ringtone it should be stored into database. //then only it is setted otherwise it wouldn't give any error but not set as default ringtone. //you can add more details BY content.put() method. 

String filepath ="/sdcard/play2.mp3";
File ringtoneFile = new File(filepath);

ContentValues content = new ContentValues();
content.put(MediaStore.MediaColumns.DATA,ringtoneFile.getAbsolutePath());
content.put(MediaStore.MediaColumns.TITLE, "chinnu");
content.put(MediaStore.MediaColumns.SIZE, 215454);
content.put(MediaStore.MediaColumns.MIME_TYPE, "audio/*");
content.put(MediaStore.Audio.Media.ARTIST, "Madonna");
content.put(MediaStore.Audio.Media.DURATION, 230);
content.put(MediaStore.Audio.Media.IS_RINGTONE, true);
content.put(MediaStore.Audio.Media.IS_NOTIFICATION, false);
content.put(MediaStore.Audio.Media.IS_ALARM, false);
content.put(MediaStore.Audio.Media.IS_MUSIC, false);
 

//Insert it into the database
Log.i(TAG, "the absolute path of the file is :"+
ringtoneFile.getAbsolutePath());
Uri uri = MediaStore.Audio.Media.getContentUriForPath(
ringtoneFile.getAbsolutePath());
Uri newUri = context.getContentResolver().insert(uri, content);
ringtoneUri = newUri; 
Log.i(TAG,"the ringtone uri is :"+ringtoneUri);
RingtoneManager.setActualDefaultRingtoneUri(context,
RingtoneManager.TYPE_RINGTONE,newUri);
