== Bundling Native Libraries ==
Sometimes you need to include a native library or two with your activity. A good strategy, the one that [[Develop]] and [[Model]] use, is to specify a shell script for the executable in the .info file:
exec = ./model_startup.sh
The script, 'model_startup.sh', modifies the library path, python, or both paths (depending on the types of libraries you are including) to point to folders inside your bundle, then launches your application:
#!/bin/sh
export PYTHONPATH=$SUGAR_BUNDLE_PATH/site-packages:$PYTHONPATH
export LD_LIBRARY_PATH=$SUGAR_BUNDLE_PATH/lib:$LD_LIBRARY_PATH
sugar-activity model_app.ModelActivity
Make sure to add your shell script and any native libraries to the MANIFEST before you package your bundle.
