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

amazon-appstore, android, google-play

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
}

Examples for rate this app links:

Google Play-

market://details?id=PACKAGANAME

Amazon Store

http://www.amazon.com/gp/mas/dl/android?p=PACKAGENAME

or

amzn://apps/android?p=com.amazon.mp3

Problem

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.
