android - Delete all shared preferences files -

i using getpreferences() method in different activities of app. means, android create different files, 1 each activity in using method.

i clear files. there way? now, delete every single file in shared_prefs directory of app, more "safety" solution.

file folder = new file(getfilesdir() + file.separator + "shared_prefs" + file.separator); if (folder.exists() && folder.isdirectory()) { string[] children = folder.list(); (int = 0; < children.length; i++) new file(folder, children[i]).delete(); }
