android - corona movieclip is not appearing on device -

i've got movieclip working on simulator, appearing during load , when played

mc1 = movieclip.newanim{ "assets/mc1.png", "assets/mc2.png", "assets/mc3.png"} mc1.x = 400 mc1.y = 200   mc1:play() -- play frames mc1:reverse{ startframe=3, endframe=1, loop=3 }  

but doesnt appear @ on samsung s2 running 4.1.2 3 png files 16kb each memory shouldnt problem

the rest of screen works fine. out there having same problem ?

thanks claude

if working in simulator should work on device. reason might not work case sensitivity of media files. check file name written in code matches file name of media file. had similar problem , realized file extension .png while wrote .png in code.

if not problem should connect device in debug mode , console output adb maybe device trowing runtime errors.
