Android Studio failed to convert drawable into a drawable
Try this:
- check names of drawables (file name must contain only abc...xyz 012...789 _ . in Resources folder ,
names have to start with lower case
MyImage.jpg == problem ,
names with space
my image.jpg == problem,
names with -
my-image.png == problem)
- check duplicate names with other extension ( my_image.jpg - my_image.png makes the problem)
- restart Android Studio
- if problem persist:
- check c:\Users\me\AndroidStudioProjects\myProject\myModule\build\intermediates\res\merged\debug\ drawable folder for corupted names or delete ALL drawable folders
- synk projekt, rebuild projekt
- if problem persist:
- restart Android Studio, wait for complete closure of the Android Studio!
