请帮我解决这个问题我很困难.谢谢

这个问题累积的时候了mActivity == null.有一篇关于类似问题的帖子,基本上说该函数是在活动onStop()方法无效后调用的mActivity.

此问题可能很快就会得到解决,因此您应该跟踪BaseGameUtils更新.截至2014年4月8日的BaseGameUtils和Google Play Services v16(4.3),这个问题很有用.

以下补丁修复了此问题 - GameHelper.java, line 849替换:

if (mConnectionResult.hasResolution()) {

有:

if ((mConnectionResult.hasResolution())&&(mActivity != null)) {
