Invoke another Apps

[Charles_M_2]

I have created two Apps, one is the main Index Apps, another is the Application Apps, which is used to show the product catalog. This two apps are store in same android device. I want to call this application Apps from the Index Apps that I have added the following statement in the index_user_script.js, but it doesn't work.

     $(document).on("click", "#home_btn_3", function(evt)
    {
         Intent intent = new Intent();
         intent.setClassName("com.dadakitchen.ecatalog.dada", "com.dadakitchen.ecatalog.dada.SplashScreenActivity");
         startActivity(intent);
         return false;
     });

Does anyone know the proper procedure to call another Apps?

On an Android device this is referred to as "intents." Here's a Google search that will provide more info.
