Android provides a way to determine whether our app is installed via playstore or by any other appliaction. It would be very handy in case if we need to perform any action only when its a valid play store build and to ignore when its a debug build or a direct apk install from any apk sharing applications

Android's PackageManager class helps us to identify the application that installed our app. Lets see how its done.

	import android.content.Context;
	import android.content.pm.PackageManager;

	public class PlayUtil {

	private static final String PLAY_STORE_REFERRER = "com.android.vending";

	/**
	* Determines if the app is installed from playstore or not
	*
	* @param context context
	* @return true if app is from playstore else false
	*/
	public static boolean isAppFromPlayStore(Context context){
	final String installReferrer = getInstallReferrer(context);
	return PLAY_STORE_REFERRER.equals(installReferrer);
	}

	/**
	* Gets the package name if the store that installed the app
	*
	* @param context context
	* @return the package name of the installer if any
	*/
	private static String getInstallReferrer(Context context){
	final PackageManager packageManager = context.getPackageManager();
	if(packageManager!=null){
	String packagename = context.getPackageName();
	return packageManager.getInstallerPackageName(packagename);
	}else{
	return null;
	}
	}
	}
