【问题讨论】：
崩溃日志，好吗？ 先生，应用程序在真实设备上崩溃，但在模拟器内显示 toast “身份验证失败”意味着任务未完成。 【参考方案1】：GoogleSignInOptions gso = new
GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
.requestIdToken(getString(R.string.default_web_client_id))
.requestEmail()
.build();
将此部分写在 onCreate() 之外并运行代码并再次在 onCreate() 中重写相同的代码，注释前一个并运行它可能会完成这项工作，我遇到了同样的问题。

【参考方案2】：-
在 Firebase 控制台中启用 googleSignIn
Android Studio 中的LoginActivity.java -
public class LoginActivity extends AppCompatActivity implements
GoogleApiClient.OnConnectionFailedListener
@BindView(R.id.sign_in_button)
SignInButton signInButton;
private FirebaseAuth mFirebaseAuth;
private GoogleApiClient googleApiClient;
private static int RC_SIGN_IN = 1;
private DatabaseReference databaseReference;
private ProgressDialog progressDialog;
@Override
protected void onCreate(@Nullable Bundle savedInstanceState)
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
ButterKnife.bind(this);
mFirebaseAuth = FirebaseAuth.getInstance();
databaseReference = FirebaseDatabase.getInstance().getReference().child("Users");
progressDialog = new ProgressDialog(this);
GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN).requestIdToken(getString(
R.string.default_web_client_id))
.requestEmail()
.build();
googleApiClient = new GoogleApiClient.Builder(this)
.enableAutoManage(this, this)
.addApi(Auth.GOOGLE_SIGN_IN_API, gso)
.build();
signInButton.setOnClickListener(new View.OnClickListener()
@Override
public void onClick(View v)
Intent signInIntent = Auth.GoogleSignInApi.getSignInIntent(googleApiClient);
startActivityForResult(signInIntent, RC_SIGN_IN);
);
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data)
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == RC_SIGN_IN)
GoogleSignInResult result = Auth.GoogleSignInApi.getSignInResultFromIntent(data);
progressDialog.setMessage("Signing in...");
progressDialog.show();
if (result.isSuccess())
GoogleSignInAccount account = result.getSignInAccount();
firebaseAuthWithGoogle(account);
else
progressDialog.dismiss();
Log.e(LoginActivity.this.getClass().getSimpleName(), "Google Sign-In failed.");
private void firebaseAuthWithGoogle(GoogleSignInAccount acct)
Log.d(LoginActivity.this.getClass().getSimpleName(), "firebaseAuthWithGooogle:" + acct.getId());
AuthCredential credential = GoogleAuthProvider.getCredential(acct.getIdToken(), null);
mFirebaseAuth.signInWithCredential(credential).addOnCompleteListener(this, new OnCompleteListener<AuthResult>()
@Override
public void onComplete(@NonNull Task<AuthResult> task)
Log.d(LoginActivity.this.getClass().getSimpleName(), "signInWithCredential:onComplete:" + task.isSuccessful());
if (!task.isSuccessful())
Log.w(LoginActivity.this.getClass().getSimpleName(), "signInWithCredential", task.getException());
Toast.makeText(LoginActivity.this, "Authentication failed.",
Toast.LENGTH_SHORT).show();
else
progressDialog.dismiss();
checkUserExist();
);
private void checkUserExist()
if(mFirebaseAuth.getCurrentUser() != null)
final String user_id = mFirebaseAuth.getCurrentUser().getUid();
databaseReference.addValueEventListener(new ValueEventListener()
@Override
public void onDataChange(DataSnapshot dataSnapshot)
if(dataSnapshot.hasChild(user_id))
Intent signinIntent = new Intent(LoginActivity.this,SplashActivity.class);
signinIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(signinIntent);
else
Intent setupAccountIntent = new Intent(LoginActivity.this,SetupAccountActivity.class);
setupAccountIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(setupAccountIntent);
@Override
public void onCancelled(DatabaseError databaseError)
);
@Override
public void onConnectionFailed(@NonNull ConnectionResult connectionResult)
Toast.makeText(this, "Connection Failed", Toast.LENGTH_LONG).show();
因此，在此活动中，当用户单击 google 登录按钮时，它会在 firebase 控制台上进行身份验证并转到设置帐户，用户可以在其中设置他们的帐户，就像您可以获取用户示例个人资料图片等的详细信息一样. 检查用户是否设置了帐户，然后它将进入启动器屏幕的启动活动。 获取用户的数据并将其保存在“用户”节点的数据库中。
SplashActivity.java - 启动器屏幕
public class SplashActivity extends AppCompatActivity
@BindView(R.id.start)
Button start;
private FirebaseAuth mFirebaseAuth;
private FirebaseUser mFirebaseUser;
private FirebaseAuth.AuthStateListener mAuthListener;
private GoogleApiClient googleApiClient;
private DatabaseReference userDatabaseReference;
@Override
protected void onCreate(@Nullable Bundle savedInstanceState)
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splash);
ButterKnife.bind(this);
mFirebaseAuth = FirebaseAuth.getInstance();
mFirebaseUser = mFirebaseAuth.getCurrentUser();
userDatabaseReference = FirebaseDatabase.getInstance().getReference().child("Users");
mAuthListener = new FirebaseAuth.AuthStateListener()
@Override
public void onAuthStateChanged(FirebaseAuth firebaseAuth)
if (mFirebaseUser == null)
Intent loginIntent = new Intent(SplashActivity.this,LoginActivity.class);
loginIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(loginIntent);
;
GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN).requestIdToken(getString(R.string.default_web_client_id))
.requestEmail()
.build();
googleApiClient = new GoogleApiClient.Builder(this)
.addApi(Auth.GOOGLE_SIGN_IN_API , gso)
.build();
checkUserExist();
private void checkUserExist()
if(mFirebaseAuth.getCurrentUser() != null)
final String user_id = mFirebaseAuth.getCurrentUser().getUid();
userDatabaseReference.addValueEventListener(new ValueEventListener()
@Override
public void onDataChange(DataSnapshot dataSnapshot)
if(!dataSnapshot.hasChild(user_id))
Intent setupAccountIntent = new Intent(SplashActivity.this,SetupAccountActivity.class);
setupAccountIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(setupAccountIntent);
@Override
public void onCancelled(DatabaseError databaseError)
);
@Override
public void onStart()
super.onStart();
googleApiClient.connect();
mFirebaseAuth.addAuthStateListener(mAuthListener);
@Override
public void onStop()
if (mAuthListener != null)
mFirebaseAuth.removeAuthStateListener(mAuthListener);
googleApiClient.disconnect();
super.onStop();
@OnClick(R.id.start)
public void onViewClicked()
Intent intent = new Intent(this,MainActivity.class);
startActivity(intent);
finish();
由于这是我的启动器活动，当用户打开应用程序时，如果未通过身份验证，它将进入登录，如果未设置帐户，则转到帐户设置活动。
【讨论】：
看起来你在同一个类中做 2 项不同的工作（正如你在我提供的代码中看到的那样。1.LoginActivity 和其他是 SplashActivity，它是启动器活动）所以 LoginActivity 处理谷歌标志在按钮单击和启动器活动中检查是否验证然后继续否则打开 LoginActivity 建议在登录类和 MainActivity 中使用 google 按钮登录，用户在打开应用程序后会看到，检查用户是否通过身份验证，否则将用户发送到登录屏幕跨度> @wahdatkashmiri 希望this 帖子对你有帮助 先生实际上我已经按照谷歌文档编写了代码我不知道是什么问题以上是关于谷歌登录验证失败的主要内容，如果未能解决你的问题，请参考以下文章
