"tPackageExplorer" is the application which checks the resource information on Android application.The tool "Hierachy Viewer" is prepared for AndroidSDK.

It is the application for developers which can be checked. When Apple Computer gets a longtime Mac user to imagine the same application (edit of a resource cannot be performed) as "ResEdit" distributed free, it may be intelligible for him. *Although it may seem that the special thing is done, no route authority is acquired.
