A problem to connect to firebase on any app I made for the last 2 years. All working perfectly until now. Now I cant get into Firebase of 10 accounts I made today from different places. I only add a button that if I clic it ask for a value of a only one variable on the real time database and doesnt work even that. I add the correct ApiKey, databaseURL and different bucketlist for test but without success. All the apps already generated that were working for years stop working in the last 24 hours. What can I do?
java.lang.NullPointerException:Attempt to invoke virtual method java.lang.String Java.lang.String.toLowerCase(java.util.Locale) on a Null object reference
I am starting without bucketlist because I need to read the full database, now I made a simple app to read a single variable and still dont connect and send me a error
Error from Companion: Attempt to invoke virtual method 'boolean java.lang.String.equals(java.lang.Object)' on a null object reference
I try with 7 kind of andorid cellphones, using android 9 to 15, not working.
