Missing variable declaration #5
Comments
I am also getting the same issue mentioned above by @MichaelsPlayground i.e. |

Hi, thanks for your wonderful contribution with this Android app - it helped me a lot in understanding how to work with Firebase.
While trying to run your I received some messages from my Android Studio (I'm running Android Studio Dolphin | 2021.3.1 Patch 1 with SDK 33).
In MessagingActivity there is a missing variable declaration:
My Android Studio claimed about a lot of possible "Method invocation 'toString' may produce 'NullPointerException'" like here:
String msg = e.child("msgText").getValue().toString();
I replaced all of those with the recommended
String msg = Objects.requireNonNull(e.child("msgText").getValue()).toString();
A last note: It would be perfect if you could add a simple explanation what services are needed in the Firebase setup - it took me some time to find them all (Authentication with Email and Google, Realtime Database and Storage).
Thanks again, greetings from
Michael
