我创建了一个应用程序，我可以在其中进行两次访问：FirebaseUI Auth和Firebase SDK身份验证（我知道这非常错误，我只为某些测试做了这个）。好吧，从我添加谷歌访问权限开始，我无法通过SDK身份验证访问，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'
}
}

repositories
{
jcenter()
maven { url 'https://maven.fabric.io/public' }
}
}
task clean(type: Delete)
{
delete rootProject.buildDir
}
这是我的gradle应用程序：

答案 0 :(得分：6)
您必须使用兼容版本的Firebase API库和Firebase用户界面。兼容版本表位于Firebase UI documentation。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'
答案 1 :(得分：6)
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。您会看到Firebase的10.2.1版本可用，但根据FirebaseUi，它目前支持最高10.2.0的Firebase版本，因此请使用10.2.0。

运行项目。
答案 3 :(得分：0)
检查Firebase的可比性版本，建议使用最新版本
就我而言，我忘记添加以下依赖项
compile 'com.google.firebase:firebase-core:9.4.0'
我的所有依赖项如下
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'
