Android:createUserWithEmailAndPassword 不起作用(firebase)

Question

我正在学习使用 Firebase，并开始创建我可以在 Firebase 控制台中看到的用户和密码。但是，方法 createUserWithEmailAndPassword 不起作用，我不知道为什么，可能是 Gradle 的问题。这是主要代码:

public class MainActivity extends AppCompatActivity
{
DialogProgress dialogProgress;
EditText editEmail;
EditText editPassword;
String email;
String password;
FirebaseAuth firebaseAuth;

@Override
protected void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    editEmail = (EditText) findViewById(R.id.editEmail);
    editPassword = (EditText) findViewById(R.id.editPassword);
    firebaseAuth = FirebaseAuth.getInstance();

    findViewById(R.id.registrazione).setOnClickListener(new View.OnClickListener()
    {
        @Override
        public void onClick(View v)
        {
            email = editEmail.getText().toString();
            password = editPassword.getText().toString();
            if(TextUtils.isEmpty(email))
            {
                Toast.makeText(getApplicationContext(),"Email vuota",Toast.LENGTH_SHORT).show();
            }

            if(TextUtils.isEmpty(password))
            {
                Toast.makeText(getApplicationContext(),"Password vuota",Toast.LENGTH_SHORT).show();
            }

            if(!(TextUtils.isEmpty(email)||TextUtils.isEmpty(password)))
            {
                dialogProgress = new DialogProgress();
                dialogProgress.show(getSupportFragmentManager().beginTransaction(),"Dialog");
                firebaseAuth.createUserWithEmailAndPassword(email,password).addOnCompleteListener(new OnCompleteListener<AuthResult>()
                {
                    @Override
                    public void onComplete(@NonNull Task<AuthResult> task)
                    {
                        if(task.isSuccessful())
                        {
                            Toast.makeText(getApplicationContext(),"Registrazione avvenuta",Toast.LENGTH_SHORT).show();
                            getSupportFragmentManager().beginTransaction().remove(dialogProgress);
                        }
                        else
                        {
                            Toast.makeText(getApplicationContext(), "Registrazione fallita", Toast.LENGTH_SHORT).show();
                            getSupportFragmentManager().beginTransaction().remove(dialogProgress);
                        }
                    }
                });

            }
        }
    });
}
}

这是我的 gradle 项目:

buildscript 
{
  repositories 
  {
    jcenter()
  }
  dependencies 
  {
    classpath 'com.android.tools.build:gradle:2.2.3'
    classpath 'com.google.gms:google-services:3.0.0'
  }
}

allprojects 
{
  repositories 
  {
    jcenter()
  }
}

task clean(type: Delete) 
{
delete rootProject.buildDir
}

这是我的 gradle 应用程序:

apply plugin: 'com.android.application'

android 
{
compileSdkVersion 25
buildToolsVersion "25.0.2"
  defaultConfig 
  {
    applicationId "com.example.utente.myfirebase"
    minSdkVersion 15
    targetSdkVersion 25
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner 
    "android.support.test.runner.AndroidJUnitRunner"
  }
buildTypes 
{
  release 
  {
  minifyEnabled false
  proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-
  rules.pro'
  }
}
}

dependencies 
{
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', 
{
    exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:25.1.0'
testCompile 'junit:junit:4.12'
compile 'com.google.firebase:firebase-auth:10.0.1'
}
apply plugin: 'com.google.gms.google-services'

尝试记录结果，以便您可以使用 Log.d("FirebaseAuth", "onComplete"+ task.getException().getMessage()); 了解问题所在可能是因为您没有激活身份验证登录方法中的电子邮件/密码选项，或者您的密码少于 6 个字符。
