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

* <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.

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.
