Cannot build ODK Collect from source (errors)

Trying to build ODK Collect from the source with Eclipse for the 1st time.
Downloaded sources with Mercurial, installed Eclipse and ADT plugin.
Imported project with Eclipse "Import..." command.
It informed me, that project "Has no properties", so I right-clicked on
project and set it to Android 2.2 version.

Now Eclipse displays, that there are some errors in sources and I don't
know, how to fix it.
Eclipse doesn't allow to build it as signed application, since there are
some errors.
I tried to build it as unsigned app and tried to install it, but my device
informed, that installation was unsuccesfull.

As far as I understand, there is something with the code, that uses some
properties, or references, that are not defined anywhere in the project.
The errors are in GeoPointMapActivity.java.
Maybe some references in my Android SDK are missing?

Screenshots of Eclipse are attached.

Figured that out - needed to install Google API in Android SDK.
