Answer 1

I spent 2 days searching for this solution, only to find out it is because of the emulator. Try to use a smartphone to run your app. For me it worked.

Answer 2

I think the problem is that you might not have added the firebase SDKs in your App.

Add the following implementation inside the dependencies in your module(app-level) Gradle file(app/build.gradle):

dependencies {
       implementation 'com.google.firebase:firebase-auth:19.3.1'
}

Answer 3

I have the same problem.

change:

mAuth.createUserWithEmailAndPassword("9199999989@pintech.com", "corrfecthorsebatterystaple")
            .addOnCompleteListener(this, new OnCompleteListener<AuthResult>()

to:

mAuth.createUserWithEmailAndPassword("9199999989@pintech.com", "corrfecthorsebatterystaple")
            .addOnCompleteListener(MainActivity.this, new OnCompleteListener<AuthResult>()

Answer 4

I had this problem too. The password I was testing the app with was just too short. I extended it to a longer password and it worked. You have to meet google's password complexity standards.

Answer 5

For me, the way I solved this issue was firstly to make sure that I had enabled Email/Password signInAuth in firebase

lastly I made sure that the line

mAuth.createUserWithEmailAndPassword(username,password)
                .addOnCompleteListener(**SignUpActivity.this**, task -> { 

... }) had myactivity.this instead of this alone as the context

Answer 6

Just for anyone still looking something that hasn't worked above:

I found that using your activity name before the this keyword in the first parameter of the .addOnCompleteListener works for me.

eg. .addOnCompleteListener(LoginActivity.this, etc..);

Hope this helps anyone still looking, Adam
