How to detect if an android app is a game?

Question

In an app I am developing I need to iterate through the installed apps and detect which ones are games. Is there any way to do this?

I was thinking to a Play Store

Correct and backwards compatible way to do this is here!

Since Android API version 21, there's finally a way to check if an application is a game.

PackageManager pm = mContext.getPackageManager();
ApplicationInfo ai = pm.getApplicationInfo(mPackageName,0);
if((ai.flags & ApplicationInfo.FLAG_IS_GAME) == ApplicationInfo.FLAG_IS_GAME)
    return true;
return false;
