I am getting a "unable to resolve target 'android-20" error... and Eclipse won't let me export the APK file. I have followed the guides to a T, and would appreciate any help here. I just want to upload an APK to Google Play for some testing of IAP and other services...thanks. Screenshot of the error: http://i.imgur.com/EbpwuNz.png
That's a rather old version of Buildbox you are using it it wants you to use API 20. We've been on API 21 for quite a while and have moved to API 23 recently. Basically it's telling you to install API 20.
