我无法登录。 即使我在Firebase中输入了电子邮件和密码，它仍会说错误日志记录

Question

The Email/Password sign-in provider's status has always been "Enabled" since the start. but it's still giving me the same error. Even from the Authentication in Firebase shows that 1. Connect your app to Firebase -> Connected (green check) 2. Add Firebase Authentication to your app -> Dependencies set up correctly (green check)

I have tried to login with email and password that I entered into the Firebase but I still can't login. It shows me Toast:

Error Logging in :(

I have been trying to find solutions from the internet. This is my current code:

            Toast.makeText(this, "Please fill up the Credentials :|", Toast.LENGTH_SHORT).show()
        }
    }
}

Expected Result is that it can direct me to home page.

Answer 1

After your edit we can now see that this is the error message:

The given sign-in provider is disabled for this Firebase project. Enable it in the Firebase console, under the sign-in method tab of the Auth section.

So you haven't enabled the provider that you're trying to sign in with. The solution is to go to the Firebase Authentication console and enable that provider.

Original response:

If a Task failed, it contains an exception with details about the failure. You should log that exception to find out why the sign-in fails.

this.mAuth.signInWithEmailAndPassword(email, password)
    .addOnCompleteListener(this, OnCompleteListener<AuthResult> { task ->
        if (task.isSuccessful) {
            startActivity(Intent(this, home::class.java))
            Toast.makeText(this, "Successfully Logged in :)", Toast.LENGTH_LONG).show()
        } else {
            Log.e("Login Error", "signInWithEmailAndPassword", task.getException());
            Toast.makeText(this, "Error Logging in :(", Toast.LENGTH_SHORT).show()
        }
    })

With the above code you can find the exception in the logcat output of your app.

Answer 2

So what I did was download another

google-services.json

and replaced it to Dir

app

and change to this

    implementation 'com.google.firebase:firebase-auth:16.0.1'
    implementation 'com.google.firebase:firebase-core:16.0.1'

in my build.gradle (Module: app) and this solved my problem.
