在跳轉之前。將父activity 新增到appManager中,不直接執行finish，在子activity 中合適的位置。比如：

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

 //TODO 移除父activity

});

或者finish子acvitity的時候複寫 

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

呼叫AppManager.finishActivityFromName(activity.class.getSimpleName())移除父activity再呼叫自身finish()方法，搞定。
