In the beginning, when Android Development was Next Big Thing we had to code in Eclipse or other available IDEs with Java Code.
As of now, you dont have to learn coding to create Android App or Web App.
Just search for "create android app without code" in Search Engine : you have list of Applications / Websites which help create Android Apps.
But the thing is you cannot implement core features while using these alternatives. Much customization can be only done by using proper IDE like Android Studio and Programming Language.
Happy Coding !!
