Question

Before everything works fine , and i rename drawable file ic_button_beat_box_default.png to ic_button_beat_box_d

Answer 1

On Windows I had a "BUILD FAILED Failed to crunch file [path]" error and solved it by closing the Android Studio project, copying the entire project folder into a location with a shorter directory path, such as my C: folder and then opening the project in the new location. Hope it helps
