I am experimenting this issue

Hello, I would like to use this library, but I am experimenting this issue:

Can you help me?

This is my code:

if (ActivityCompat.checkSelfPermission(context, Manifest.permission.READ_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED) {
            com.kevalpatel.ringtonepicker.RingtonePickerDialog.Builder ringtonePickerBuilder = new com.kevalpatel.ringtonepicker.RingtonePickerDialog
                    .Builder(context, context.getSupportFragmentManager())

                    //Set title of the dialog.
                    //If set null, no title will be displayed.
                    .setTitle("Select ringtone")

                    //set the currently selected uri, to mark that ringtone as checked by default.
                    //If no ringtone is currently selected, pass null.
                    .setCurrentRingtoneUri(defaultSelectedRingtone)

                    //Set true to allow allow user to select default ringtone set in phone settings.
                    .displayDefaultRingtone(true)

                    //Set true to allow user to select silent (i.e. No ringtone.).
                    .displaySilentRingtone(true)

                    //set the text to display of the positive (ok) button.
                    //If not set OK will be the default text.
                    .setPositiveButtonText("SET RINGTONE")

                    //set text to display as negative button.
                    //If set null, negative button will not be displayed.
                    .setCancelButtonText("CANCEL")

                    //Set flag true if you want to play the sample of the clicked tone.
                    .setPlaySampleWhileSelection(true)

                    //Set the callback listener.
                    .setListener(new RingtonePickerListener() {
                        @Override
                        public void OnRingtoneSelected(@NonNull String ringtoneName, Uri ringtoneUri) {
                            //Do someting with selected uri...
                        }
                    });

            //Add the desirable ringtone types.
            ringtonePickerBuilder.addRingtoneType(com.kevalpatel.ringtonepicker.RingtonePickerDialog.Builder.TYPE_MUSIC);
            ringtonePickerBuilder.addRingtoneType(com.kevalpatel.ringtonepicker.RingtonePickerDialog.Builder.TYPE_NOTIFICATION);
            ringtonePickerBuilder.addRingtoneType(com.kevalpatel.ringtonepicker.RingtonePickerDialog.Builder.TYPE_RINGTONE);
            ringtonePickerBuilder.addRingtoneType(com.kevalpatel.ringtonepicker.RingtonePickerDialog.Builder.TYPE_ALARM);

            ringtonePickerBuilder.show();
        }else {
            ActivityCompat.requestPermissions(context, new String[]{
                        Manifest.permission.WRITE_EXTERNAL_STORAGE
                    },
                    123);
        }

I am using version 1.3

With 1.2 version I am experimenting the following issue:

Of course I have tried to give Storage permission to the app and it has it, but I am not getting this library works.

Hello! I have the exact same problem. Through the settings, I turned on the permissions and checked its presence, but it still falls with a message about the lack of access.

[EbelloImbox]

I tried to use this library, but I never got any help, so I surrendered and I changed my way and I did it by myself.

[Leeeeerich]

I am set ".setCurrentRingtoneUri(null)" and it work.
I also found another problem (inconsistency). It is written that you need READ_EXTERNAL_STORAGE, but in fact you need more WRITE_EXTERNAL_STORAGE, too. For ".addRingtoneType(RingtonePickerDialog.Builder.TYPE_MUSIC)"
