Detect if an Android app was downloaded from Google Play vs Amazon vs Other

I know this is probably a longshot, but is there any way to detect programatically whether an app was hosted on the Amazon apps store vs on Google Play? I would like to link to the app store the app was downloaded from, and I'd rather not have two different APKs with just this difference if it can be avoided.

Solution

  • As of just recently, the Amazon Appstore returns sane values for PackageManager.getInstallerPackageName()

    PackageManager pm = context.getPackageManager();
String installerPackageName = pm.getInstallerPackageName(context.getPackageName());

if ("com.android.vending".equals(installerPackageName)) {
    //do google things
} else if ("com.amazon.venezia".equals(installerPackageName)) {
    //do amazon things
}
