Only white screen at my app whenever i open it


I have a project (adminapk.apk) 1 week ago and it has been completed, and I have downloaded and run it and it is fine, however when I create a new application with another name (pegunungan.apk) it cannot be installed instead it installs the application (adminapk.apk), so I took the initiative to delete the admin.apk first to try the gunung.apk but it is still the same after that I re-download the project (adminapk.apk) and I run it on my smartphone but the screen is just white, and when I try to use this ai company it says ("Error from Companion: Attempt to invoke virtual method 'boolean java.lang.String.equals(java.lang.Object)' on a null object reference") I make data monitoring using firebase please help me

Firebase is broken.

Also, be sure to change the app name in Project Properties to avoid overwrite of other apps at install time.


before I deleted the adminapk app (about 1 hour ago) I had a chance to fiddle with the values ​​from my firebase, and it still works on the adminapk app, so the problem is with this new mitt app, right? Oh my god, I've already deleted the old app that still works, when will mittapp and firebase work again?

See the alternative Firebase access techniques in the Firebase FAQ.

Only the component is broken.
