Google登錄身份驗證失敗

Question

我想將Google登錄集成到我的應用中，但它沒有將我引向其他活動，它顯示了模擬器中唯一的身份驗證失敗，但是當我在真實設備上對其進行測試時，該應用停止了單擊Google登錄按鈕的操作。 這是我的下面的代碼

Answer 1

GoogleSignInOptions gso = new 
GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
        .requestIdToken(getString(R.string.default_web_client_id))
        .requestEmail()
        .build();

在onCreate（）之外編寫此部分並運行代碼，然后在onCreate（）中再次注釋前面的代碼並再次重寫相同的代碼，然后運行它可能會完成這項工作，我遇到了同樣的問題。

Answer 2

1. 在Firebase控制台中啟用googleSignIn

2. 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，在此活動中，當用戶單擊google登錄按鈕時，它將在firebase控制台上進行身份驗證並轉到設置帳戶，用戶可以在該帳戶中設置其帳戶，就像您可以獲取用戶示例個人資料圖片等的詳細信息一樣。用戶，如果他已經設置了帳戶，那么它將進入啟動活動，即您的啟動器屏幕。 獲取用戶數據並將其保存在“用戶”節點中的數據庫中。

3. SplashActivity.java-啟動器屏幕

    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(); } 

   }

因為這是我的啟動器活動，所以如果用戶未通過身份驗證就打開該應用程序，則它將登錄；如果未設置帳戶，則進入帳戶設置活動。
