Question

我正在尝试在Firebase中注册新用户，但由于某种原因它会返回错误。我正在使用android studio中的firebase工具进行连接包com.parse.starter;

import android.support.annotation.NonNull;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.widget.Toast;

import com.google.android.gms.tasks.OnCompleteListener;
import com.google.android.gms.tasks.Task;
import com.google.firebase.auth.AuthResult;
import com.google.firebase.auth.FirebaseAuth;
import com.google.firebase.auth.FirebaseUser;

public class MainActivity extends AppCompatActivity {
    private FirebaseAuth mAuth;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mAuth = FirebaseAuth.getInstance();
        mAuth.createUserWithEmailAndPassword("abraham_mew@yahoo.com", "123456789juk")
                .addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
                    @Override
                    public void onComplete(@NonNull Task<AuthResult> task) {
                        if (task.isSuccessful()) {
                            // Sign in success, update UI with the signed-in user's information
                           ;
                           System.out.print("SUCKSESSS");

                        } else {
                            // If sign in fails, display a message to the user.
                           System.out.print(("FAILE"));

                        }

                        // ...
                    }
                });
    }
}

这是Logcat

Caused by: java.lang.IllegalStateException: Default FirebaseApp is not initialized in this process com.parse.starter. Make sure to call FirebaseApp.initializeApp(Context) first.
