错误使用LibGdx与谷歌播放

Question

我使用Eclipse，LibGdx 1.0.1，谷歌最新的游戏库服务/ BaseGameUtils（摇篮），以及最新BaseGameUtils从https://github.com/playgameservices/android-samples

（摇篮项目）

我BaseGameUtils有几个错误

GameHelper.java

// Api options to use when adding each API, null for none 
GoogleApiClient.ApiOptions mGamesApiOptions = null; //error with this line 
GoogleApiClient.ApiOptions mPlusApiOptions = null; //error with this line 
GoogleApiClient.ApiOptions mAppStateApiOptions = null; //error with this line 

/** 
* Sets the options to pass when setting up the Games API. Call before 
* setup(). 
*/ 
public void setGamesApiOptions(GoogleApiClient.ApiOptions options) { //error with this line 
    doApiOptionsPreCheck(); 
    mGamesApiOptions = options; //error with this line 
} 

/** 
* Sets the options to pass when setting up the AppState API. Call before 
* setup(). 
*/ 
public void setAppStateApiOptions(GoogleApiClient.ApiOptions options) { //error with this line 
    doApiOptionsPreCheck(); 
    mAppStateApiOptions = options; //error with this line 
} 

/** 
* Sets the options to pass when setting up the Plus API. Call before 
* setup(). 
*/ 
public void setPlusApiOptions(GoogleApiClient.ApiOptions options) { //error with this line 
    doApiOptionsPreCheck(); 
    mPlusApiOptions = options; //error with this line 
} 

/** 
* Creates a GoogleApiClient.Builder for use with @link{#setup}. Normally, 
* you do not have to do this; use this method only if you need to make 
* nonstandard setup (e.g. adding extra scopes for other APIs) on the 
* GoogleApiClient.Builder before calling @link{#setup}. 
*/ 
public GoogleApiClient.Builder createApiClientBuilder() { 
    if (mSetupDone) { 
     String error = "GameHelper: you called GameHelper.createApiClientBuilder() after " 
       + "calling setup. You can only get a client builder BEFORE performing setup."; 
     logError(error); 
     throw new IllegalStateException(error); 
    } 

    GoogleApiClient.Builder builder = new GoogleApiClient.Builder(
      mActivity, this, this); 

    if (0 != (mRequestedClients & CLIENT_GAMES)) { 
     builder.addApi(Games.API, mGamesApiOptions); //error with this line 
     builder.addScope(Games.SCOPE_GAMES); 
    } 

    if (0 != (mRequestedClients & CLIENT_PLUS)) { 
     builder.addApi(Plus.API, mPlusApiOptions); //error with this line 
     builder.addScope(Plus.SCOPE_PLUS_LOGIN); 
    } 

    if (0 != (mRequestedClients & CLIENT_APPSTATE)) { 
     builder.addApi(AppStateManager.API, mAppStateApiOptions); //error with this line 
     builder.addScope(AppStateManager.SCOPE_APP_STATE); 
    } 

    mGoogleApiClientBuilder = builder; 
    return builder; 
} 

所以我添加//error with this line与你猜对错误。

就像我之前提到的，我相信我有最新的库，并且我确信我的项目链接正确。我在我的AndroidManifest.xml文件中也有必要的代码行。

Answer 1

在Google Play游戏服务4.4中有一些API尚未反映在Android示例项目中（https://github.com/playgameservices/android-samples/tree/master/BasicSamples/libraries/BaseGameUtils）或Google记录（据我所知）。

看一看对G + Android开发者入门的评论：

https://plus.google.com/+AndroidDevelopers/posts/8957tqzymuM

您可以使用修改GameHelper社区，等待谷歌更新示例项目或推翻GPGS 4.3。

使用可以在这里找到，而不是代码：https://gist.github.com/EmmanuelVinas/ef09a35bcc805ba6deb3

就削减一切从GameHelper.java的进口它的结束，然后是要点的内容粘贴作为替代。

它的工作原理

Answer 3

我用源从https://github.com/playgameservices/android-samples/tree/master/BasicSamples/libraries/BaseGameUtils/src/main/java/com/google/example/games/basegameutils但我的应用程序有以下错误崩溃：

java.lang.NullPointerException: Null options are not permitted for this Api at 
.. com.google.example.games.basegameutils.GameHelper.createApiClientBuilder(GameHelper.java:286 ) at 
com.google.example.games.basegameutils.GameHelper.setup(GameHelper.java:319) at 
com.google.example.games.basegameutils.BaseGameActivity.onCreate(BaseGameActivity.java:105). 

我已经改变BaseGameActivity onCreate方法：

@Override 
protected void onCreate(Bundle b) { 
    super.onCreate(b); 
    if (mHelper == null) { 
     getGameHelper(); 
    } 
    mHelper.setPlusApiOptions(new Plus.PlusOptions.Builder().build()); 
    mHelper.setup(this); 
} 

和错误消失。
