NullPointer on toLowerCase but I don't use that method anywhere

Question

I\'m getting the following crash dump in Firebase Crash Reports:

Exception java.lang.NullPointerException: Attempt to invoke virtual method \'java.lang.Strin         


        

Answer 1

I got this error when my code was trying to create a connection to certain amqp service using an invalid URL. Once I modified it to the proper value, the exception is gone. So check your code.
