Android：NoSuchMethodError：没有静态方法zzy（Ljava / lang / Object;

Question

我创建了一个应用程序，我可以在其中访问两个波：FirebaseUI Auth和Firebase SDK身份验证（我知道这是非常错误的，我只在某些测试中使用它）。 好吧，从我添加谷歌访问权限，我无法访问SDK身份验证，应用程序总是崩溃，我不知道为什么。 这是我的代码：

public class MainActivity extends AppCompatActivity
{
DialogProgress dialogProgress;
EditText editEmail;
EditText editPassword;
String email;
String password;
FirebaseAuth firebaseAuth;
final int REQUEST_CODE_GOOGLE = 100;
static Activity activity;

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

    if(firebaseAuth.getCurrentUser()!=null)
    {
        Toast.makeText(getApplicationContext(), "Bentornato " + firebaseAuth.getCurrentUser().getEmail().toString(), Toast.LENGTH_SHORT).show();
        Intent intent = new Intent(MainActivity.this,ProfileActivity.class);
        startActivity(intent);
        finish();
    }

    findViewById(R.id.accediButton).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.setLayout(0);
                dialogProgress = new DialogProgress();
                dialogProgress.setCancelable(false);
                dialogProgress.show(getSupportFragmentManager().beginTransaction(),"Dialog");

                firebaseAuth.signInWithEmailAndPassword(email, password).addOnCompleteListener(MainActivity.this, new OnCompleteListener<AuthResult>() {
                    @Override
                    public void onComplete(@NonNull Task<AuthResult> task)
                    {
                        if (task.isSuccessful())
                        {
                            dialogProgress.dismiss();
                            Toast.makeText(getApplicationContext(), "Bentornato " + firebaseAuth.getCurrentUser().getEmail().toString(), Toast.LENGTH_SHORT).show();
                            Intent intent = new Intent(MainActivity.this,ProfileActivity.class);
                            startActivity(intent);
                            finish();
                        }
                        else
                        {
                            dialogProgress.dismiss();
                            Toast.makeText(getApplicationContext(), "Login fallito " + task.getException().toString(), Toast.LENGTH_LONG).show();
                        }
                    }
                });
            }
        }
    });

    findViewById(R.id.registratiText).setOnClickListener(new View.OnClickListener()
    {
        @Override
        public void onClick(View v)
        {
            Intent intent = new Intent(MainActivity.this,RegistrazioneActivity.class);
            startActivity(intent);
        }
    });

    findViewById(R.id.accediGoogle).setOnClickListener(new View.OnClickListener()
    {
        @Override
        public void onClick(View v)
        {
            AuthUI authUi = AuthUI.getInstance();
            Intent intent = authUi.createSignInIntentBuilder().build();
            startActivityForResult(intent,REQUEST_CODE_GOOGLE);
        }
    });

}

@Override
public void onActivityResult(int codice, int risultato, Intent data)
{
    super.onActivityResult(codice, risultato, data);
    if(codice==REQUEST_CODE_GOOGLE && risultato==RESULT_OK && data!=null)
    {
        IdpResponse idpResponse = IdpResponse.fromResultIntent(data);
        Toast.makeText(getApplicationContext(),idpResponse + "",Toast.LENGTH_LONG).show();
    }
}
}

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

    jcenter()
    maven { url 'https://maven.fabric.io/public' }
  }
}

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

Answer 1

您必须使用兼容版本的Firebase API库和Firebase UI。 兼容版本表位于Firebase UI文档中 。 将com.google.firebase:firebase-*库的9.4.0更改为10.2.0。

compile 'com.android.support:appcompat-v7:25.1.0'
compile 'com.google.firebase:firebase-auth:10.2.0'
compile 'com.google.firebase:firebase-database:10.2.0'
compile 'com.google.firebase:firebase-storage:10.2.0'
compile 'com.firebaseui:firebase-ui-auth:1.2.0'
compile 'com.android.support.constraint:constraint-layout:1.0.2'
testCompile 'junit:junit:4.12'

Answer 2

改变这个：

compile 'com.google.firebase:firebase-auth:9.4.0'
compile 'com.google.firebase:firebase-database:9.4.0'
compile 'com.google.firebase:firebase-storage:9.4.0'

对此：

compile 'com.google.firebase:firebase-auth:10.2.0'
compile 'com.google.firebase:firebase-database:10.2.0'
compile 'com.google.firebase:firebase-storage:10.2.0'

您需要升级Firebase，您使用的是旧版本。 您将看到Firebase的10.2.1版本可用，但根据FirebaseUi它目前支持的Firebase版本高达10.2.0，因此请使用10.2.0。

Answer 3

1. 正如在此处提到的那样，将所有版本更新为最新版本 ，所有版本都应该相同 。
2. 清理并重建您的项目

运行该项目。

Answer 4

检查firebase的可比性版本，建议使用最新版本

在我的情况下，我忘了添加以下依赖项

compile 'com.google.firebase:firebase-core:9.4.0'  

我的所有依赖如下

compile 'com.google.firebase:firebase-core:9.4.0'
compile 'com.google.firebase:firebase-messaging:9.4.0'
compile 'com.firebase:firebase-client-android:2.5.1' 

所有用于向设备发送推送通知
