Question

我正在使用Firebase并创建我的注册流程。

对于常规电子邮件/密码身份验证，我可以成功写入Cloud Firestore。我已经在实际数据库中查看了我的数据，所以我知道它已成功写入：

           @Override
        public void onComplete(@NonNull Task<Void> task) {
            Log.v("INPUT_TEXT", user.getDisplayName());
            Toast.makeText(getApplicationContext(), user.getDisplayName().toString(), Toast.LENGTH_LONG).show();
            Map<String, Object> userMap = new HashMap<>();
            userMap.put("Display_Name", user.getDisplayName());
            userMap.put("ID", user.getUid());
            userMap.put("Provider", user.getProviders());
            mStoreBaseRef.collection("Users").add(userMap);
        }
    });

但是，使用Facebook身份验证：

private void handleFacebookAccessToken(AccessToken token) {
    Log.d(TAG, "handleFacebookAccessToken:" + token);

    AuthCredential credential = FacebookAuthProvider.getCredential(token.getToken());
    mAuth.signInWithCredential(credential)
            .addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
                @Override
                public void onComplete(@NonNull Task<AuthResult> task) {
                    Log.d(TAG, "signInWithCredential:onComplete:" + task.isSuccessful());
                    FirebaseAuth loggedInAuth = FirebaseAuth.getInstance();
                    String ID = loggedInAuth.getCurrentUser().getUid();
                    String displayName = mAuth.getCurrentUser().getDisplayName();
                    HashMap<String, Object> id = new HashMap<>();
                    id.put("user_id", ID);
                    id.put("display_name", displayName);
                    id.put("provider", mAuth.getCurrentUser().getProviderData());
                    mStoreBaseRef.collection("Users").add(id);

                    // If sign in fails, display a message to the user. If sign in succeeds
                    // the auth state listener will be notified and logic to handle the
                    // signed in user can be handled in the listener.
                    if (!task.isSuccessful()) {
                        Log.w(TAG, "signInWithCredential", task.getException());
                        Toast.makeText(getApplicationContext(), "Authentication failed.",
                                Toast.LENGTH_SHORT).show();

                    } else {
                        Toast.makeText(getApplicationContext(), "Authentication_Success", Toast.LENGTH_LONG).show();
                    }

                }
            });

我收到以下错误：

如果我们无法将您提供给我们的类型自动转换为我们支持的类型（类似于custom objects），就会发生此错误。检查您放入userMap的类型，如有必要，请选择更简单的类型。（有关详细信息，请参阅文档。）
