I\'ve been trying to create an application that uses Google Maps and upon getting an error for \"MapActivity\" I searched the web and found the solution was to make my build
I encountered the same problem
Go here to manually download the Google APIs. For example, I use GoogleAPI level 8, so I download the package here
After downloading just extract the zip file to "C:\Program Files (x86)\Android\android-sdk\add-ons" and rename the directory to "google_apis-8" instead of "google_apis-8_r02".
