When you first build project buendia, the gradle will ask for any missing and needed SDK components, you just have to accept the suggestions.
If you are running windows, you will have to change some paths to build the app. inside the gradle file theres two paths to JARs that works on linux but does not work in windows, actually they are redirects to the libs. you have to substitute that path with a windows compliant path (can be a absolute or relative path to the 3rd party libs). And if you have an AMD computer, make sure AMD-V is enabled in the BIOS, otherwise the emulator wont work.
dont forget to see
https://github.com/projectbuendia/client/issues/3 and change the openmrsRootUrlDefault so that the app can find the server.
That should work...
