Thanks for your reply. I've imported the project as a module in the new Android studio because they convert Eclipse format to Gradle. It imported almost everything except libre-sdk.jar, which seems kindof important. I may try to import it as Eclipse if possible. At least there were no compilation errors. I would like to know if I could expect a basic operating app after I get it working, or could you tell me how many things I need to 'hook up' to get the java working with some buttons on the HelloWorld activity?
