I've used the following code to set the ringtone in my app which is working fine. Now i would like to provide the option to remove the ringtone and reset the ringtone back. Please help me on this. Thanks in advance.
Uri path = Uri.parse("android.resource://"
+ getPackageName() + "/raw/ringtone");
RingtoneManager.setActualDefaultRingtoneUri(
getApplicationContext(),
RingtoneManager.TYPE_RINGTONE, path);
After taking existingRingtonepath, you can set your custom ringtone path.
Uri existingRingtonePath = getDefaultUri(RingtoneManager.TYPE_RINGTONE);
After that you can use it to revert back.
RingtoneManager.setActualDefaultRingtoneUri(
getApplicationContext(),
RingtoneManager.TYPE_RINGTONE, existingRinftonePath);
If you want to revert to default then,
RingtoneManager.setActualDefaultRingtoneUri(
getApplicationContext(),
RingtoneManager.TYPE_RINGTONE, RingtoneManager.DEFAULT_RINGTONE_URI);
