android - 使用 Firebase 登录 Google 失败

Question

我正在尝试使用 Firebase 实现 Google Auth 方法，但登录失败。 Logcat 失败时不会显示任何红色文本。我设置了我的 SHA 1，但它仍然无法正常工作。我使用 Kotlin 。

登录 Activity .kt

    private var googleApiClient: GoogleApiClient? = null
    private var rootRef: FirebaseFirestore? = null

        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_login)
        rootRef = FirebaseFirestore.getInstance()

        google_sign_in_button.setOnClickListener { signIn() }

        firebaseAuth = FirebaseAuth.getInstance()
        authStateListener = FirebaseAuth.AuthStateListener { auth ->
            val firebaseUser = auth.currentUser
            if (firebaseUser != null) {
                val intent = Intent(this, MainActivity::class.java)
                startActivity(intent)
                finish()
            }
        }

        val googleSignInOptions = GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)

            .addApi(Auth.GOOGLE_SIGN_IN_API, googleSignInOptions)
            .build()
    }

    private fun signIn() {
        val signInIntent = Auth.GoogleSignInApi.getSignInIntent(googleApiClient)
        startActivityForResult(signInIntent, RC_SIGN_IN)
    }

    public override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
        super.onActivityResult(requestCode, resultCode, data)
        if (requestCode == RC_SIGN_IN) {
            val task = GoogleSignIn.getSignedInAccountFromIntent(data)
            try {
                val googleSignInAccount = task.getResult(ApiException::class.java)
                if (googleSignInAccount != null) {
                    firebaseSignInWithGoogle(googleSignInAccount)
                }
            } catch (e: ApiException) {
                makeText(this, "Google sign in failed!", LENGTH_SHORT).show()
            }
        }
    }

    private fun firebaseSignInWithGoogle(googleSignInAccount: GoogleSignInAccount) {
        val authCredential = GoogleAuthProvider.getCredential(googleSignInAccount.idToken, null)
        firebaseAuth!!.signInWithCredential(authCredential).addOnCompleteListener(this) {
            val firebaseUser = firebaseAuth!!.currentUser
            if (firebaseUser != null) {
                createUserIfNotExists(firebaseUser)
            }
        }
    }

    private fun createUserIfNotExists(firebaseUser: FirebaseUser) {
        val uid = firebaseUser.uid
        val userName = firebaseUser.displayName
        val user = User(uid, userName!!)

        val uidRef = rootRef!!.collection("users").document(uid)
        uidRef.get().addOnCompleteListener { task ->
            if (task.isSuccessful) {
                val document = task.result
                if (!document!!.exists()) {
                    uidRef.set(user)
                }
            }
        }
    }

    public override fun onStart() {
        super.onStart()
        firebaseAuth!!.addAuthStateListener(authStateListener!!)
    }

    public override fun onStop() {
        super.onStop()
        if (firebaseAuth != null) {
            firebaseAuth!!.removeAuthStateListener(authStateListener!!)
        }
    }

    companion object {
        //private val TAG = "LoginActivity"
        private const val RC_SIGN_IN = 123
    }
}

我不知道可能是什么问题，我是否应该制作另一个 Android Studio 项目并复制粘贴代码，然后在 Firebase 项目中添加另一个应用程序？

只需在 firebase 中设置项目时检查一下，您是否在公共(public)设置中添加了支持电子邮件？ .因为几天前我遇到了同样的问题，唯一缺少的是我的 Firebase 控制台中的支持电子邮件 ID。
