推荐答案

首先，这不是你谁打开该PDF之一。您与其他应用程序中打开它，因此，如果渲染速度较低时，你能做的唯一的事情就是选择其他应用程序的openeing它。这不是你的责任，你的情况下，它不是在所有涉及到异步任务。我认为这将是有益供您阅读有关首款Android基础所有的和获得华南简介Android框架一些knowlege以及它是如何工作的。

First of all, it's not you the one who open this pdf. You open it with other application, so if rendering speed is low, the only thing you can do is select other app for openeing it. It's not your responsibility and in your case it's not related to asynchronous tasks at all. I think it will be usefull for you to read about Android Fundamentals first of all and get some more knowlege abour Android framework and how it works.
