FirebaseAuthWithPlayGames致命异常:由java.lang.IllegalArgumentException引起的java.lang.RuntimeException给定字符串为空或为null

Question

你好，我有一个完整的工作代码，通过谷歌游戏登录在球员登录。请参阅此代码片段

 GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_GAMES_SIGN_IN)
            .requestServerAuthCode("720182182679-fv285c7k5kecqhqdmc9ggc9f73jc9hef.apps.googleusercontent.com")
            .build();

    mGoogleSignInClient = GoogleSignIn.getClient(start.this, gso);


    mGoogleApiClient = new GoogleApiClient.Builder(this)
            .addApi(Games.API)
            .addScope(Games.SCOPE_GAMES)
            .addApi(Auth.GOOGLE_SIGN_IN_API, gso)
            .build();




 private void startSignInIntent() {
    GoogleSignInClient googleSignInClient = GoogleSignIn.getClient(this, GoogleSignInOptions.DEFAULT_GAMES_SIGN_IN);
    Intent intent = googleSignInClient.getSignInIntent();
    startActivityForResult(intent, RC_SIGN_IN);
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == RC_SIGN_IN) {
        GoogleSignInResult result = Auth.GoogleSignInApi.getSignInResultFromIntent(data);
        if (result.isSuccess()) {

            // The signed in account is stored in the result.
            GoogleSignInAccount signedInAccount = result.getSignInAccount();
            assert signedInAccount != null;
            Toast.makeText(start.this, "Google Play Games Connectet", Toast.LENGTH_SHORT).show();

        } else {

            String message = result.getStatus().getStatusMessage();
            new AlertDialog.Builder(this).setMessage(message)
                    .setNeutralButton(android.R.string.ok, null).show();
        }
    }
}

上面的代码工作得很好。但如果我想触发下面的方法，游戏就会崩溃，并在标题中显示错误。

private void firebaseAuthWithPlayGames(GoogleSignInAccount acct) {
    Log.d(TAG, "firebaseAuthWithPlayGames:" + acct.getId());
    AuthCredential credential = PlayGamesAuthProvider.getCredential(acct.getServerAuthCode());
    mAuth.signInWithCredential(credential)
            .addOnCompleteListener(this, 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();
                    updateUI(user);
                } else {
                    // If sign in fails, display a message to the user.
                    Log.w(TAG, "signInWithCredential:failure", task.getException());
                    Toast.makeText(start.this, "Authentication failed.",
                            Toast.LENGTH_SHORT).show();
                    updateUI(null);
                }

                // ...
            });
}

   @Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == RC_SIGN_IN) {
        GoogleSignInResult result = Auth.GoogleSignInApi.getSignInResultFromIntent(data);
        if (result.isSuccess()) {

            // The signed in account is stored in the result.
            GoogleSignInAccount signedInAccount = result.getSignInAccount();
            assert signedInAccount != null;
   --------->   firebaseAuthWithPlayGames(signedInAccount);   <-----------
            Toast.makeText(start.this, "Google Play Games Connectet", Toast.LENGTH_SHORT).show();

        } else {

            String message = result.getStatus().getStatusMessage();
            new AlertDialog.Builder(this).setMessage(message)
                    .setNeutralButton(android.R.string.ok, null).show();
        }
    }
}

我希望有人已经面对了这个问题，并能提供帮助。

我认为这是因为它没有在游戏服务和Firebase之间正确获取令牌

您必须在play控制台中配置链接到同一游戏的web应用程序。然后从web应用程序复制客户端id，并将其粘贴到插件的设置对话框中。

步骤在这里..。https://firebase.google.com/docs/auth/android/play-games

仔细检查以下步骤：

启用Google Play游戏作为登录提供商：

查找项目的web服务器客户端ID和客户端密码。web服务器客户端ID向Google Play身份验证服务器标识您的Firebase项目。

要查找这些值：

在Google API控制台凭证页面中打开Firebase项目。在Web2.0client IDs部分，打开OAuth client (由Google Service自动创建)详细信息页面。此页列出您的web服务器客户端ID和密码。然后，在Firebase控制台中，打开Authentication部分。

在“登录方法”选项卡上，启用“玩游戏”登录提供程序。您将需要指定项目的web服务器客户端ID和客户端密码，它们是从API控制台获得的。
