I am trying to build an app with android studio 3.5 , I want to use Firebase, but whenever I open up the Firebase assistant window an IDE exception error pops up. I've tried disabling and re-enabling the firebase plugins, I've even reinstalled Android Studio. Please help me.

Here's the error:

java.util.NoSuchElementException

  • Hello and welcome on SO! take a look at https://docs.oracle.com/javase/8/docs/api/java/util/NoSuchElementException.html as it might help you understand the problem! `Thrown by various accessor methods to indicate that the element being requested does not exist.` – pep 1 Sep 28 '19 at 09:24
  • @pep1 it sounds like OP has this problem when starting a plugin in Android Studio, in which case their own code is unlikely to be involved, and thus no way for them to fix it by changing that code. – Frank van Puffelen Sep 28 '19 at 09:45

    Hey Stephan, if this happens before you even write any code, it is unlikely that anyone here can help, and more likely a bug in the Firebase Assistant. Please [file a bug report](https://firebase.google.com/support/contact/bugs-features/) with the Firebase team. – Frank van Puffelen Sep 28 '19 at 09:46
  • I recommend also not using the Firebase Assistant, as it's known to have problems. There is documentation for getting started without the assistant, and I highly recommend doing things that way. – Doug Stevenson Sep 28 '19 at 11:04
