I found a way that works! And it is simple. A co-worker of mine has this
slogan on his whiteboard: "Do the simplest thing that could possible work."
I have my main app, which contains both free and paid code. I also have an
app that acts as a key to unlock the pro version.
The following code tells me if my main app should be running in free or paid
mode:
public class PaidMode
{
public static boolean isInPaidMode(Context context)
{
String mainAppPkg = ...;
String keyPkg = ...;
int sigMatch = context.getPackageManager.checkSignatures(mainAppPkg,
keyPkg);
return sigMatch == PackageManager.SIGNATURE_MATCH;
}
}
Anywhere I want to have different functionality between modes I can just
call that method.
Hope this helps someone else as well!
Thanks,
Justin
