How can I clear the Android app cache?

Question

I am writing a app which can programatically clear application cache of all the third party apps installed on the device. Following is the code snippet for Android 2.2

Answer 1

Check out android.content.pm.PackageManager.clearApplicationUserData: http://grepcode.com/file/repository.grepcode.com/java/ext/com.google.android/android/2.3.3_r1/android/content/pm/PackageManager.java/ The other hidden methods in that class might be useful, too.

In case you've never used hidden methods before, you can access hidden methods using Java reflection.
