Install time for Android application?

Question

Is there any way to determine programmatically the time at which an Android application was installed? I don\'t see anything in PackageInfo, etc.

--EDIT-- To clarify

Answer 1

are you trying to find the time when YOUR app was installed, or other apps? If you are only interested in your own app, you can add functionality to your app that checks if this is the first time the app has been run. if it is, get the system time and save it in a file/database. then whenever you want it, you can open the file/query the database for it.

Answer 2

When you install/update a non-protected app, it's apk file gets written to /data/app/package.name.apk, confusingly referenced as sourceDir (from my answer) resetting the timestamp to the current one. That's it.

Answer 3

Register a BroadcastReceiver for the corresponding Intent.
