所以我被这个令人沮丧的问题困住了。 我在Firebase上使用Google身份验证还比较新，但我已经按照Firebase文档中有关如何集成Google SignIn身份验证的说明完成了所有步骤，但是我仍然在控制台中收到这个由两部分组成的奇怪错误:
12-03 11:07:40.090 2574-3478/com.google.android.gms E/TokenRequestor: You have wrong OAuth2 related configurations, please check. Detailed error: UNREGISTERED_ON_API_CONSOLE
并且
Google sign in failed com.google.android.gms.common.api.ApiException: 10:
在任何人试图指出以前在stackoverflow 上已经被问过的类似问题之前，这是我迄今为止所做的工作，在看到所有可用的解决方案之后，没有一个解决了错误。
- 我有我的项目的SHA1指纹
- 我有我的OAuth 2.0客户端ID，包括android客户端ID和Web客户端ID，并且在requestIdToken()中，我放置了Web客户端ID。
- 我没有发布我的项目APK在Google Play商店上。这意味着我没有意外地生成另一个SHA1指纹。
- 我按照Google登录认证Firebase文档一步一步地操作。
以下是我的代码片段：
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_signup);
ButterKnife.bind(this);
String webClientId = getString(R.string.web_client_id);
GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
.requestEmail()
.requestIdToken(webClientId)
.build();
mGoogleApiClient = new GoogleApiClient.Builder(this)
.enableAutoManage(this /* FragmentActivity */, this /* OnConnectionFailedListener */)
.addApi(Auth.GOOGLE_SIGN_IN_API, gso)
.build();
mGoogleSignInClient = GoogleSignIn.getClient(this, gso);
GoogleSignInAccount account = GoogleSignIn.getLastSignedInAccount(this);
googleLoginBtn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Intent signInIntent = mGoogleSignInClient.getSignInIntent();
startActivityForResult(signInIntent, RC_SIGN_IN);
}
});
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
// Result returned from launching the Intent from GoogleSignInClient.getSignInIntent(...);
if (requestCode == RC_SIGN_IN) {
// The Task returned from this call is always completed, no need to attach
// a listener.
Task<GoogleSignInAccount> task = GoogleSignIn.getSignedInAccountFromIntent(data);
try{
GoogleSignInAccount account = task.getResult(ApiException.class);
firebaseAuthWithGoogle(account);
} catch (ApiException e) {
// Google Sign In failed, update UI appropriately
Log.w(TAG, "Google sign in failed", e);
// [START_EXCLUDE]
Toast.makeText(this, "Gooogle Auth failed", Toast.LENGTH_LONG);
// [END_EXCLUDE]
}
}
}
private void firebaseAuthWithGoogle(GoogleSignInAccount acct) {
Log.d(TAG, "firebaseAuthWithGoogle:" + acct.getId());
// [START_EXCLUDE silent]
//showProgressDialog();
// [END_EXCLUDE]
AuthCredential credential = GoogleAuthProvider.getCredential(acct.getIdToken(), null);
mAuth.signInWithCredential(credential)
.addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
if (task.isSuccessful()) {
// Sign in success, update UI with the signed-in user's information
Log.d(TAG, "signInWithCredential:success");
FirebaseUser user = mAuth.getCurrentUser();
Toast.makeText(LoginActivity.this, "Successful Auth", Toast.LENGTH_LONG).show();
} else {
// If sign in fails, display a message to the user.
Log.w(TAG, "signInWithCredential:failure", task.getException());
Toast.makeText(LoginActivity.this, "Authentication failed.",
Toast.LENGTH_SHORT).show();
//updateUI(null);
}
// [START_EXCLUDE]
//hideProgressDialog();
// [END_EXCLUDE]
}
});
}
