How do I check if ringtone pointed by uri exists?
android, java, ringtone, uri
Solution
`getRingtone()` will return null if the ringtone does not exist.
Always check that a returned value is not null, this is a good practice whenever you call methods that might return null value. This will prevent a whole lot of `NullPointerException`
Problem
I'm able to play a ringtone using the following code ``` rone = RingtoneManager.getRingtone(this.getContext(), Uri.parse(one)); rone.play(); ``` How do I check if the audio file pointed by uri exists? When the user deletes a file from their phone, I'm not able to play the ringtone and it crashes.
