As I see your package.name is com.appybuilder.dhirajanand2009.OnlineToysShop
this is the default setting:
if you want to change the package-name use e.g.
then, for the screens use
But the most important in your case: rename your project name into the middle part of your package name
there´s a issue betwenn App Name and Project Name (OnlineToyShopppp and OnlineToyShop)
also be sure you use the correct name here: OnlineToysShop or OnlineToyShop
