Clear android application data programmatically

Question

Manually I can do

Settings -> Applications -> Manage applications -> (choose my app) -> Clear data

How do I do this programmatically?

I need to delete all data, including those in shared preferences (, and variables).

Answer 1

Everything in your application is stored here /data/data/com.example.applicationpackagename/ .

Your application is run by a user which has R/W access on this directory.

You just need to remove every files in it.

Answer 2

You could use following code in which "packagename" could be your application package name like com.example.app1

Intent intent = new Intent();
intent.setData(Uri.parse("package:" + packageName));
