How use RingtoneManager.setType() in Delphi

Using Androidapi.JNI.Media with Delphi 10.2 Tokyo.

I am trying to list the available ringtones and play a different one from current default.

Initialization of JAudioManager and JRingtoneManager seems ok, because I can play the default ringtone.

But when I try to use the RingtoneManager to set Type, or get a Cursor, the program terminates with a system popup which say "The Application (name) was interrupted - restart the app".

procedure TAudioPlayBackForm.Button2Click(Sender: TObject);
var
  AudioObj: JObject;
  AudioMgr: JAudioManager;
  RingtoneMgr: JRingtoneManager; 
  aUri: Jnet_Uri;
  cur: JCursor;
  ringt: JRingtone;
begin
  AudioObj := TAndroidHelper.Activity.getSystemService(TJContext.JavaClass.AUDIO_SERVICE );
  RingtoneMgr := TJRingtoneManager.Wrap((AudioObj as ILocalObject).GetObjectID);
  Log.d('TJRingtoneManager wrap ok');

  aUri := TJRingtoneManager.JavaClass.getActualDefaultRingtoneUri(SharedActivityContext, TJRingtoneManager.JavaClass.TYPE_NOTIFICATION);
  Log.d('getActualDefaultRingtoneUri = '+ JStringToString(aUri.toString) );                                                        

  ringt := TJRingtoneManager.JavaClass.getRingtone(SharedActivityContext, aUri);
  Log.d('getRingtone uri ok = '+ JStringToString( ringt.getTitle(SharedActivityContext) ));

  ringt.play;  // OK !

  RingtoneMgr.setType( 4 );   // <-- CRASH !
  Log.d('RingtoneMgr setType ok');

  cur := RingtoneMgr.getCursor;   // <-- CRASH !
  Log.d('RingtoneMgr getCursor ok = '+ intToStr(cur.getColumnCount));
end;

Any idea? Did I forget to initialize something?

I used this documentation as reference.

You're creating the RingtoneManager instance incorrectly. It should be:

// Forget about obtaining AudioObj - it's not relevant
RingtoneMgr := TJRingtoneManager.JavaClass.init(TAndroidHelper.Activity);

This requires the Androidapi.Helpers unit
