Description

From the listing uploaded by “kikvalgar81”.

This application does absolutely nothing. It was originally created for Android development and testing. It is useful for testing application condition detection, app launching and killing, and auto task killer priority management. Unlike other "nothing" apps, this actually does what is described. There is no blank window. There is no UI, and the app icon is transparent.

Null App APK: questions and answers

Can I install this APK over the version I already have?

Only if it is signed with the same certificate as the copy on your phone and isn't an older version. If Android says “App not installed”, the certificates differ; uninstalling your copy first works but deletes its data unless it is backed up.

Is the Null App APK safe?

No one can promise that a file is safe, but some things can be checked. The source store rates this file Trusted. After downloading, check that the file's MD5 is 451479a92b8688f8660dd697fbf731da.
