what to do if the image is not present in drawable folder of android studio code example

Example: what to do if the image is not present in drawable folder of android studio

It seems like you are adding images correctly using the Android Studio
context menu. Another way you can add images to drawable folder
(if you are running on Windows OS) is to right click the drawable folder
and choose "Show in Explorer". Then you can drag and drop the images directly
into the drawable folder
