No this not working too. I manually copied the files because at first time I build my app this screen was shown to me. So, I thought that my project was empty and manually copying was my check
Did you ever find a fix for this? I’m experiencing the same issue. I have to manually copy files from www into /build to update my compiled app. Somhow, even if I delete files from project/www, project/src and build/android, when I run ionic cordova emulate android, it restores these old files. I don’t even know where it is storing them.
