Android - Adding Images To Project
问题 I am brand new to Android and I am using Eclipse ADT to create a simple application. This application has a button that changes it's background image based on user clicks. I noticed that there are 4 folders for images in my project: drawable-hdpi, drawable-ldpi, drawable-mdpi, and drawable-xhdpi . and I also noticed that the images that are in there currently (the launcher icon) are all different sizes. Does this mean that I have to use some image editing software to create one image for each
