暂不明原因！

临时解决方案：

在onCreateDialog()中创建dialog的时候，传入最外层的ActivityGroup

初步原因：

当请求服务器的时候，后台线程返回数据时，调用了activity的showDialog()，但是这个时候恰巧

activity已经被finish掉了，导致报错

Unable to add window -- token android.os.BinderProxy@424ce168 is not valid; is your activity running?

解决办法：在showDialog之前 判断activity是否被finish掉， activity.isFinishing()
