接入 OppoSDK时遇见的一个问题

游戏在接入时遇见了一个比较奇怪的问题，取消支付时返回游戏显示的是欢迎页面

查看log信息时，发现在点击支付时抛出了以下的错误信息：

看了半天没想出是哪的错误，最后通过查看录屏时发现，原来在支付时activity发生了旋转，导致activity重新生成了，这也就解释了为什么会显示欢迎页面（ps：欢迎页面是在activity当中添加的）。解决方法是在activity声明中添加android:configChanges="keyboardHidden|orientation|screenSize"，关于configChanges的说明参看http://blog.csdn.net/akiyame/article/details/44923335。
