推荐答案

从根本上说：不能，至少不是没有生根。 主要原因安卓不允许您将应用程序安装到你的外置SD卡有：

"Basically speaking: You can't. At least not without rooting. The main reasons Android does not allow you to install an application to your external SD card are:

安全性：这是主要的原因的限制。像NTFS或FAT（任何版本的话）的基本文件系统不容许类Unix许可管理。 这意味着：任何应用程序都可以写上存储的任何文件。 恶意应用程序的思想，他们将能够用假/感染换上合适的应用程序，砌体您的手机并使其无法使用。

Security: It's the main reason for that restriction. Basic file systems like NTFS or FAT (any version of it) do not allow for Unix-like permission management. This means: any application would be able to write to any file on that storage. Thinking of malicious apps, they would be able to replace proper apps with fake/infected ones, bricking your phone and rendering it unusable.

易失性存储器：你的外置SD卡是不是安全，可以在设备中所有的时间插入。您可以将其弹出任何时候是什么让你的SD卡不是一个很好的候选人为永久存储。考虑流失你的SD卡的应用程序，你弹出。这些应用程序只会崩溃并保存在SD卡上的所有其他应用程序都没有了为好。你可以不使用它们当时和这些应用程序中的数据也受到理由＃1。

Volatile storage: Your external SD card is not safe to be inserted in your device all the time. You are able to eject it any time what makes your SD card not a very good candidate for a permanent storage. Consider apps running off of your SD card and you eject it. Those apps will just crash and all other apps saved on your SD card are gone as well. You can't use them at that time and the data of those app is also affected by reason #1."
