How to add a background image in main.xml in anyother directory structure except @drawable

Hello
I am trying to use this but it is giving error

android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="/assets/images/mybackgrounds/bg.png"

I want to know how can we give background image at a particular location in layout file like main.xml

Welcome to JavaRanch Asif!

If you have your image resource in drawable folder you can refer them as follows:
android:background="@drawable/resource_name".

If you bundle them in assets, then you will have to read these files as streams using AssetManager and then create a Bitmap from these stream using BitmapFactory. After this is done, you can set this Bitmap as background property of your View or ViewGroup in code.

Putting an image resource in drawable folder is NOT JUST copying an image file to a folder in the Project's structure.(Read official documentation on Application Resources). Android tools(aapt et al.) do a lot of stuff behind the scenes.

Just curious to know when should we ideally use assets folder ???
