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 met the same problem and it said "access is denied". I am using 64bit win7 and the sdk tools is installed under C:\Program Files (x86)\Android\android-sdk. I figure out that it is because the SDK manager does not have permission to the folder so the quick fix is to right click SDK manager and run it as administrator.
Try clearing your cache (Tools > Options > Clear Cache), then reloading (Packages > Reload), and see if that helps.
Run as Administrator did the trick from me in Windows7. SDK mgr is showing all extra google apis too after this.
If you're using the latest version of the SDK (ADK 14), the Google API packages should be located in the folder containing the appropriate SDK level in the SDK manager.
For example, for Android 2.2, there should be a folder called "Android 2.2 (API 8)" which should contain the SDK "SDK Platform" and additional pieces such as the Google APIs "Google APIs by Google, Inc.".
Sometimes Google Server is down or return 502 error, so you cannot find any manifest file. This happened to me. The solution is to wait for a couple of minutes.
