Simple test program

I'm using the most recent versions of sdl-1.3 and SDL_image from HG. My build environment is Ubuntu 11.10 x86_64.
I've built a simple test program which loads an image and displays it for 5 seconds. The image fails to load, and the app is just a black screen that remains open.
'adb logcat' displays the following:

(loads all .so files just fine)

I think I am having a similar problem as described in this post:

I'm also getting an 'invalid renderer'
Comment 2 Dan Hatch 2012-04-20 14:28:59 UTC 
Tested on 2.1 and 4.0.3 emulators and a 2.3 device. All platforms show same errors.
Comment 3 Gabriel Jacobo 2012-05-11 11:32:25 UTC 
You are loading the image from an absolute path outside of the Android package. By default IMG_Load under Android will, iirc, load images using RWops and the paths have to be specified relative to the assets folder (ie, whatever you drop into the assets folder of the Android project you can load it as if it where in a "virtual root").

Ok, cool thanks, I'll give it a try :)
