when I develop a custom button with LiveCode, I met a problem: I just follow the lesson(https://lessons.livecode.com/m/4071/l/6852-how-to-create-a-rollover-button-with-icon-images) to make a custom button, it can't show in the android Emulator when i test it, and also can't show on the real moblie phone when I save as a standalone application . Is anybody knows the reason or met the similar problem?
Thanks a lot.
