    }

I work with Unity Android games. The task is to open a Facebook Fan page in the FB app if it is installed. All I need to do is:

1. Create Android Library and check if FB installed:

    public boolean isFbInstalled(Activity a) { PackageManager packageManager = a.getApplicationContext().getPackageManager(); try { int versionCode = packageManager.getPackageInfo("com.facebook.katana", 0).versionCode; if (versionCode >= 3002850) { //newer versions of fb app, no need to handle older return true; } } catch (PackageManager.NameNotFoundException e) { return false; } return false;

   }
