get package installer

Issue

I'd like to add an unlocker for my app, which is only available on the Play Store. How can I check, if the package was installed by the Play Store? I've seen this in SD Maid, but I didn't find a solution yet.

Solution

I found a method for that: PackageManager.getInstallerPackageName(String packageName); This returns the package name of the installer application.
