@DA:
I've uninstalled Eclipse and all related stuff at the moment in preparation for another try to get things working. Consequently I'm not sure if our errors are an exact match. From your screenshots and descriptions, I do recognize a lot. I've encountered the following:
- R cannot be resolved to be a variable
- The import com.mycompany cannot be resolved
- gen is missing
- src-related stuff was wrong (can't recall the particular error-message)
- files have been missing (e.g. the facebook-sdk-jar I posted for you in the 'step-by-step'-thread was one of the things I ran into as well)
- HardCodedCompileScript-business missing and/or not working
Frustrating stuff, to be sure
If I have another go, I'll try to note down the things that have been changed since the step-by-step guide was posted.
