Firebase 身份验证错误：我启用了电子邮件/密码选项

Question

我正在尝试使用 Android 登录 Firebase，但收到了奇怪的消息：

Code Picture Here

login.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

            final String Email,Pass;
            Email=email.getText().toString();
            Pass=pass.getText().toString();
            if(!TextUtils.isEmpty(Email) && !TextUtils.isEmpty(Pass))
            {
                progressBar.setVisibility(View.VISIBLE);
                if(Pass.length()>=6)
                {
                    auth = FirebaseAuth.getInstance();
                    auth.signInWithEmailAndPassword(Email, Pass).addOnCompleteListener(new OnCompleteListener<AuthResult>() {
                        @Override
                        public void onComplete(@NonNull Task<AuthResult> task)
                        {
                            progressBar.setVisibility(View.INVISIBLE);
                            if (task.isSuccessful())
                            {
                                Intent i = new Intent(login.this, MainActivity.class);
                                i.putExtra("Email",Email);
                                startActivity(i);
                                finish();
                            }
                            else
                            {
                                progressBar.setVisibility(View.INVISIBLE);
                                Toast.makeText(login.this, "" + task.getException(), Toast.LENGTH_SHORT).show();
                            }
                        }
                    });
                }
                else
                {
                    progressBar.setVisibility(View.INVISIBLE);
                    Toast.makeText(login.this, "Password Must be 8 Character Long", Toast.LENGTH_SHORT).show();
                }

            }
            else
            {
                progressBar.setVisibility(View.INVISIBLE);
                Toast.makeText(login.this, "Provide Email and Password", Toast.LENGTH_SHORT).show();
            }

        }
    });

构建.Gradle

apply plugin: 'com.android.application'

android {
    compileSdkVersion 27
    defaultConfig {
        applicationId "com.butt************"
        minSdkVersion 19
        targetSdkVersion 26
        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 'com.google.firebase:firebase-database:11.8.0'
        implementation fileTree(dir: 'libs', include: ['*.jar'])
        implementation 'com.android.support:appcompat-v7:27.0.1'

        implementation 'com.google.android.gms:play-services-maps:11.8.0'
        implementation 'com.google.firebase:firebase-database:11.8.0'
        testImplementation 'junit:junit:4.12'
        compile 'com.google.firebase:firebase-auth:11.8.0'
        androidTestImplementation 'com.android.support.test:runner:1.0.1'
        androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
        implementation 'com.android.support:design:27.0.1'

        apply plugin: 'com.google.gms.google-services'
        implementation 'com.google.android.gms:play-services-ads:11.8.0'


    }
    apply plugin: 'com.google.gms.google-services'

带有错误消息：

W/BiChannelGoogleApi: [FirebaseAuth: ] getGoogleApiForMethod() 返回 Gms D/ViewRootImpl：来自应用信息的缓冲区计数，使用 ::-1 && -1 for :: com.butt.mediacalradar 来自 View :: -1 DBQ Enabled ::false false

"com.google.firebase.FirebaseException. An internal Error Occur [Bad Request]".

更新后

apply plugin: 'com.android.application'

    compileSdkVersion 27
    defaultConfig {
        applicationId "com**********"
        minSdkVersion 19

            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

    apply plugin: 'com.google.gms.google-services'

}
apply plugin: 'com.google.gms.google-services'

Answer 1

为了使其正常工作，请对所有依赖项使用最新版本：

首先将 google 服务版本（build.gradle 项目）更改为：

classpath 'com.google.gms:google-services:4.0.1'

以及来自的依赖项：

compile 'com.google.firebase:firebase-database:11.8.0'
implementation 'com.google.android.gms:play-services-maps:11.8.0'
implementation 'com.google.firebase:firebase-database:11.8.0'
compile 'com.google.firebase:firebase-auth:11.8.0'
implementation 'com.google.android.gms:play-services-ads:11.8.0'

到

//compile 'com.google.firebase:firebase-database:11.8.0'
implementation 'com.google.android.gms:play-services-maps:15.0.1'
implementation 'com.google.firebase:firebase-database:16.0.1'
implementation 'com.google.firebase:firebase-auth:16.0.1'
implementation 'com.google.android.gms:play-services-ads:15.0.1'
implementation 'com.google.firebase:firebase-core:16.0.0'

如您所见，第一行已被注释。不要忘记删除重复的apply plugin: 'com.google.gms.google-services'。应该只保留在文件的末尾。
