Answer 1

If you're not root (and have access to Market database), I don't think it's possible.

Answer 2

In your activity do

PackageManager pm = getPackageManager();
String installationSource = pm.getInstallerPackageName(getPackageName());

installationSource will now hold the package name of the app that installed your app.

testing with an app of mine installation source is "com.google.android.feedback" when installed via google market, null if installed via debugger.
