load lua files from apk #7

I'm trying to use OpenQuick with Android but get the runtime error: "Failed to load QConfig.lua file". Most likely, it is because 'luaL_loadfile' function can't load files from a apk archive.

You are right. Lua uses standard C I/O functions like fopen(), fread(). Whilst these compile with the Android NDK, they can only open/read assets that have already been decompressed to somewhere on the device filesystem... they cannot read them directly from the compressed APK.

Your best bet is probably to write some Java code that decompresses the contents of the APK's resource folder to disk, then the Lua file operations should behave themselves.

e.g. Google "Android fopen", for discussions like this: http://stackoverflow.com/questions/1992953/file-operations-in-android-ndk

I'm new in Android programming, but I think extracting apk's content to a disk is not good practice. May be it will be better if OpenQuick extracts lua files to the memory and then executes it.
