My project have many images in Background Picture list, but only 3 images has be used in my project. I make a test, download the apk (46,0mb), put a new image in list (but i don’t put in any screen, only in Background Picture list) and after this my apk has a 46,6mb.
Can I clean this list, remove the image that I dont use?
You are using the Legacy UI, also called Snap to Place.
In your project editor screen go to the left side (not the side that has the image you shared). In the left side the pane is divided into upper and lower.
In the upper pane scroll down to see the Files section. You can delete the images from there.
