Is There A Way To Make My Android App Run Some Custom Code Upon Installation?

I have some ideas about running some anti-piracy measures for my app so I wondered if I could do this to sign the application on install. Running the code on first launch is no goo

Solution 1:

There is no way to run code on install on Android unfortunately, only run on first launch.

If you're interested in anti-piracy measures you'll find this post on the Android Developers blog about securing the Android License Verification Library interesting, if you haven't read it already.
