Update
I've discovered that the issue occurs when a URL such as the one below is added to the database. How would you save it so the error doesn't happen?
Hi all I'm getting the error Failed to bounce to type at com.firebase.client.DataSnapshot.getValue. It on this bit of code here but I don't know how to fix it:
Person person = postSnapshot.getValue(Person.class);
Here is the full code:
