I can\'t start new projects anymore. This is what I do...
I had the same problem yesterday after updating the latest packages on the Android SDK Manager.
Fixed it by updating the Eclipse plugin: Run Eclipse
> Help
> Install new software
> Paste the URL
https://dl-ssl.google.com/android/eclipse/ then press Enter
. After updating the plugin, I created a test project with the main activity and menu was created by default as normal.
