I want to report a problem that other users might have experienced.
If you have attempted to install market before using the guide on this thread, make sure you delete all the files (e.g googleframework.apk - vendor.apk) you downloaded to try and make market work.
I had tried to install market previously, without any luck, and then saw this guide. I went to online content and installed Market. I didn't work, I was rather puzzled, but then I realised that the files I had previously downloaded to try and make Market work were conflicting. So I deleted all the files I had downloaded, uninstalled all the relevant things on the virtual phone. Then I went to online content and installed market and it worked!
Am very happy I saw this guide, thanks!
