How android app can detect what store installed it?

Question

I have app in Google Play, Amazon, Samsung Apps and I plan to upload to other stores. I do not wish to compile separate build for every store. Is there way to detect what store installed app if same app submitted to different stores?

Answer 1

You'll have to expand this for each additional store, but this should get you started

if (context.getPackageManager().getInstallerPackageName(context.getPackageName()).equals("com.android.vending")
{
//do google things
}
else if (context.getPackageManager().getInstallerPackageName(context.getPackageName()).equals("com.amazon.venezia")
{
//do amazon things
}
