Is there no way to overcome this issue?
Sure. Create a Resourcefolder with the needed files. reference the folder in your project.
Asuming you named the folder "res" and put the folder in your projectdir.
then
res/values/wheel__attrs.xml
res/drawable/divider_dark_gradient_horizontal.xml
res/drawable/wheel_bg_hor.xml
res/drawable/wheel_bg_ver.xml
res/drawable/wheel_val.xml
res/layout/spinner_item.xml
these are the folderstructue which must be present.
Last you need to add a reference to this folder in your project.
PS: No need to mark any files here writeprotected as files in this folder(s) are not deleted when compiling.
