Question

我已经创建了一个应用，今天已上传到Alpha测试轨道。但是我面临一些问题。我已经实现了Firebase身份验证（Google登录）。将应用上传到Play商店后，Google登录失败（在Play商店上载应用之前，身份验证工作正常）。

以下是代码（Google登录）

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

        mGoogleSignInClient = GoogleSignIn.getClient(this, gso);

signInButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                signIn();
            }
        });

private void signIn() {

        Intent signInIntent = mGoogleSignInClient.getSignInIntent();
        startActivityForResult(signInIntent, RC_SIGN_IN);

    }

@Override
    protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        if (requestCode == RC_SIGN_IN) {
            Task<GoogleSignInAccount> task = GoogleSignIn.getSignedInAccountFromIntent(data);
            handleSignIn(task);
        }

    }

    private void handleSignIn(Task<GoogleSignInAccount> completedTask) {

        try {
            // Google Sign In was successful, authenticate with Firebase
            GoogleSignInAccount account = completedTask.getResult(ApiException.class);
            Toast.makeText(this, "success", Toast.LENGTH_SHORT).show();
            firebaseAuthWithGoogle(account);
        } catch (ApiException e) {
            // Google Sign In failed, update UI appropriately
            Log.e("TAG_failure", "Google sign in failed");
            Toast.makeText(this, "Failed", Toast.LENGTH_SHORT).show();
        }

    }

    private void firebaseAuthWithGoogle(GoogleSignInAccount acct) {

        loadingDialog.show();

        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()) {
                            loadingDialog.dismiss();
                            Log.d("TAG_S", "signInWithCredential:success");
                            FirebaseUser user = mAuth.getCurrentUser();
                            //firebaseDataHandler();
                            queryData();
                            authLayout.setVisibility(View.GONE);
                        } else {
                            // If sign in fails, display a message to the user.
                            Log.e("TAG_F", "signInWithCredential:failure", task.getException());
                            //updateUI(null);
                            loadingDialog.dismiss();
                        }
                    }
                });
    }

这是 build.gradle

buildTypes {
        release {
            shrinkResources true
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

        }
    }

上传应用程序到游戏机后，Google in app购买也无法正常工作

在 proguard-rules.pro 中，我添加了这一行

-keep class com.android.vending.billing.**

我还添加了“结算”权限，但我不知道为什么这不起作用

<uses-permission android:name="com.android.vending.BILLING" />

有我不知道的令人困惑的问题吗？

在此先感谢您的帮助。
