When I click finish in the 'new android project' window the window doesn't close itself. I have to close the window manually. When I'm looking at the new project the folders are white and the src folder haven't got the MainActivity that I have just created in the 'new android project' window. I reinstalled eclipse and the sdk stuff but it didn't help. In the project properties I click 'android' and eclipse says: The currently displayed page contains invalid values. I use Eclipse Indigo 4.2 and Android SDK Manager Revision 20.
Sometimes reinstalling Eclipse and Android SDK doens't work properly. When I started with it I got the same problem and fixed it by deleting Eclipse's folder AND the Android's folders created when I installed it (by default Android's folders can be found in C:\ )
I deleted the folder 'Android' and '.android', only after that I downloaded again Eclipse and Android SDK. Try doing this and follow carefully the instructions to install the ADT Plugin
