i'm making preloader large application. today error occurred "no such file or directory". error occurs on android device. on computer(in simulator) works fine. file names , directories lowercase.
code:

m.dial = display.newimagerect( m.gr, textures.interface["btn_compas_comp.png"].filename, textures.interface["btn_compas_comp.png"].basedir, 272, 272 ) m.dial.x, m.dial.y = x, y thanks in advance friends.
1) all file names , directories lowercase - suggest double-check because android filesystem case sensitive.
2) check build.settings ensure excludefiles section doesn't include of directories code
edit: idea based on corona lfs doc - try following before loading:
local resourcespath = system.pathforfile( "", system.resourcedirectory ) -- change current working directory local success = lfs.chdir( resourcespath ) --returns true on success i guess lfs doesn't point on resource directory default. assets should in directory, don't try modify them - for security reasons, directory read-only , enforced operating system, not corona.
edit 2: solution don't rely on current directory
preloader.createpath = function() k, v in pairs(path) local = 0 local pathfordirectory = system.pathforfile(v, system.resourcedirectory) preloader.texture[k] = { id = k } l in lfs.dir(pathfordirectory) if ( l ~= "." , l ~= ".." , l ~= "..." ) = + 1 preloader.texture[k][i] = v..l end end end end
