android - Google Play服务GameHelper NPE createApiClientBuilder(此API不允许使用null选项)

由于最新的Google Play服务和Android Studio更新(0.5.9)，我收到了这个令人讨厌的错误。
当我使用GameHelper开始 Activity 时，应用程序崩溃了。
这些错误是我对制作应用失去兴趣的原因。
我有Google GitHub页面上的最新版本的GameHelper。

Activity :

mmmHelper = new GameHelper(this, GameHelper.CLIENT_ALL);

GameHelper.GameHelperListener listener = new GameHelper.GameHelperListener() {
            @Override
            public void onSignInSucceeded() {
                // handle sign-in succeess
            }
            @Override
            public void onSignInFailed() {
                // handle sign-in failure (e.g. show Sign In button)
            }

        };
        mmmHelper.setup(listener);


        mGoogleApiClient = new GoogleApiClient.Builder(this)
                .addApi(Games.API)
                .build();
        mGoogleApiClient.connect();

        Log.d(TAG, "Starting setup.");
        mHelper.startSetup(new IabHelper.OnIabSetupFinishedListener() {
            public void onIabSetupFinished(IabResult result) {
                Log.d(TAG, "Setup finished.");

                if (!result.isSuccess()) {
                    // Oh noes, there was a problem.
                    Log.d(TAG, "Problem setting up In-app Billing: " + result);
                }
                // Hooray, IAB is fully set up!
                mHelper.queryInventoryAsync(mGotInventoryListener);
            }
        });

最佳答案

我通过将CLIENT_ALL更改为CLIENT_GAMES来解决了崩溃问题!

问题:

mmmHelper = new GameHelper(this, GameHelper.CLIENT_ALL);

新鲜:

mmmHelper = new GameHelper(this, GameHelper.CLIENT_GAMES);

我仅使用Games.API，因此这可能是该应用程序因CLIENT_ALL而崩溃的原因。

mGoogleApiClient = new GoogleApiClient.Builder(this)
                .addApi(Games.API)
                .build();
mGoogleApiClient.connect();
