Setting a custom ringtone without explicit permission of WRITE_SETTINGS

Question

I simple want to set the ringtone. I don't want to give permission of WRITE_SETTINGS, i can find most of the answer to give permission of WRITE_SETTINGS but there is an app i am using that app has not any WRITE_SETTINGS permission to set the ringtone

https://play.google.com/store/apps/details?id=com.atomic.apps.ringtone.cutter

When you install this app it never ask permission explicitly android.permission.WRITE_SETTINGS (also in marshmallow)

this is the method to pick the ringtone from storage

public void pickRingtone()
{
    Intent intent = new Intent(RingtoneManager.ACTION_RINGTONE_PICKER);
    intent.putExtra(RingtoneManager.EXTRA_RINGTONE_TYPE, RingtoneManager.TYPE_RINGTONE);
    intent.putExtra(RingtoneManager.EXTRA_RINGTONE_TITLE, "Select Ringtone");
    Uri urie = RingtoneManager.getActualDefaultRingtoneUri(getApplicationContext(), RingtoneManager.TYPE_RINGTONE);
    intent.putExtra(RingtoneManager.EXTRA_RINGTONE_EXISTING_URI, urie);
    startActivityForResult(intent, REQUEST_CODE);
}

// here i am going to set the ringtone

        @Override
        protected void onActivityResult(int requestCode, int resultCode, Intent data) 
        {
if (requestCode == REQUEST_CODE) {
        if (resultCode == RESULT_OK) 
        {
            Uri uri = data.getParcelableExtra(RingtoneManager.EXTRA_RINGTONE_PICKED_URI);
            if (uri != null)
            {
                String ringTonePath = uri.toString();
                RingtoneManager.setActualDefaultRingtoneUri(context, RingtoneManager.TYPE_RINGTONE, uri);
            }
        }
    }
}

but i am getting this error

Please help. Thanks in advance.

Answer 1

You must have to use android.permission.WRITE_SETTINGS in your code and ask user to explicitly grant this permission to make your code/application work. There is no other to do that without the use of WRITE_SETTINGS permission.

Also the application from Google you have mentioned is also using this WRITE_SETTINGS permission (modify system settings). Check the below screenshot for more information:

For how to use WRITE_SETTINGS check below references:

1. Official documentation : https://developer.android.com/reference/android/Manifest.permission#WRITE_SETTINGS
2. One of the best answer on SO : https://mcmap.net/q/223936/-can-39-t-get-write_settings-permission

Answer 2

The way you use you must have to use android.permission.WRITE_SETTINGS I just install that app and looking the way he uses I believe in 2 things

• get the default URI for ringtone and rewrite the audio byte stream.
• Just replace the default ringtone if you can

Microcyte

I think it can be helpful, Now i have the byte stream of my new ringtone and the URI of default ringtone, so can you tell me how to replace the exact URI?? – Obumbrate
