content.put(MediaStore.MediaColumns.TITLE, "test");
content.put(MediaStore.MediaColumns.SIZE, 215454);
content.put(MediaStore.MediaColumns.MIME_TYPE, "audio/*");
content.put(MediaStore.Audio.Media.ARTIST, "artist");
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);

Log.i(TAG,"the ringtone uri is :"+ringtoneUri);
RingtoneManager.setActualDefaultRingtoneUri(context,
RingtoneManager.TYPE_RINGTONE,newUri);
