我想删除的用户全SD卡编程中的Andr​​oid 2.2。

什么是做到这一点的最简单的方法是什么？

它会需要root权限？

我可以做一个室射频到/ mnt / SD卡或做我必须做一个递归循环？

您可以删除目录与Java。你要做的是递归的，如果他们不为空： HTTP：//www.exampledepot .COM / EGS / java.io / DeleteDir.html

没有。所有的应用程序都完全RW访问外部存储器。

是的，你可以执行shell命令（但你必须检查是否RM可用）：Any的方式来运行在Android编程？

检查可用的命令：How我可以得到有关Android的壳可用命令外壳信息？

I wish to delete the users entire SDcard programmatically in Android 2.2.

What is the easiest way to do this?

Will it require root rights?

Can I just do an "rm -rf /mnt/sdcard" or do I have to make a recursive loop?

You can delete directories with Java. You have to do it recursively if they are not empty: http://www.exampledepot.com/egs/java.io/DeleteDir.html

No. All applications have full RW access to external storage.

Yes you can execute shell commands (but you'll have to check if "rm" is available): Any way to run shell commands on android programmatically?

Checking for available commands: How can I get information from the shell about commands available in Android shell?
