[工作积累] Google Play Services

注意添加APP_ID

      <meta-data android:name="com.google.android.gms.games.APP_ID"
         android:value="@string/app_id" />
      <meta-data android:name="com.google.android.gms.version"
          android:value="@integer/google_play_services_version"/>

 

使用对应的AndroidInitialization方法

 *
 * The appropriate initialization function must be called exactly once before
 * any AndroidPlatformConfiguration instance methods are called, and it must be
 * called before a GameServices object is instantiated. It is permitted to
 * instantiate a AndroidPlatformConfiguration before one of the intialization
 * calls (for example, if the configuration object has global scope), as long as
 * no methods are called before the initialization call. These methods need be
 * called only once in the lifetime of the calling program, not once per

API Level 14以上: OnActivityResult必须调用, 其他不需要.  14以下都需要.

gpg-cpp-sdk/android/include/gpg/android_support.h

#ifndef __cplusplus
#error Header file supports C++ only
#endif  // __cplusplus

#include "gpg/common.h"

namespace gpg {

/**
 * Functions which enable pre- Android 4.0 support.
 *
 * <h1>Android Lifecycle Callbacks</h1>
 *
 * For apps which target Android 2.3 or 3.x devices (API Version prior to 14),
 * Play Game Services has no way to automatically receive Activity lifecycle
 * callbacks. In these cases, Play Game Services relies on the owning Activity
 * to notify it of lifecycle events. Any Activity which owns a GameServices
 * object should call the AndroidSupport::* functions from within their own
 * lifecycle callback functions. The arguments in these functions match those
 * provided by Android, so no additional processing is necessary.
 *
 * For apps which target android 4.0+ (API Version greater than or equal to 14),
 * most of these function calls are unnecessary. For such apps only the
 * OnActivityResult function must be called.

遇到的问题:

response code 4: item unavailable

"the item you requested is not available for purchase"

http://developer.android.com/google/play/billing/v2/billing_reference.html

RESULT_ITEM_UNAVAILABLE　　　　4

Indicates that Google Play cannot find the requested item in the application's product list. This can happen if the product ID is misspelled in your REQUEST_PURCHASE request or if an item is unpublished in the application's product list.

对照检查, 我这里的问题是第6条:

dev console上上传的的APK, versionCode为6, 设备测试用的APK, versionCode 12.

将本地设备使用的版本号改为6, 问题解决. 估计将新版本的APK上传到dev console也可以解决这个问题.
