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?
