activity 跳转后finish由于动画出现黑屏的补救

在跳转之前。将父activity 添加到appManager中,不直接执行finish，在子activity 中合适的位置。比如：

getWindow().getDecorView().post(new Runnable() {

 //TODO 移除父activity

});

或者finish子acvitity的时候复写 

@Override
public void finish() {
 //TODO 移除父activity
   super.finish();
}

调用AppManager.finishActivityFromName(activity.class.getSimpleName())移除父activity再调用自身finish()方法，搞定。
