Sample projects to load dex file (dalvik executable code) and res file (android resources, probably packaged in the same apk file) into the current android runtime environment.
You can develop a new version of SampleActivity in project ActivityDeveloper, generate a apk to ActivityLoader/assets/apks/ and launch that SampleActivity in ActivityLoader.
The SampleActivity cannot have it's own resources.
You can develop com.dianping.example.SampleFragment in project FragmentDeveloper, generate a apk to FragmentLoader/assets/apks/ and launch that apk in FragmentLoader.
The SampleFragment can also load resources.
