Part 1
I downloaded the latest version of Eclipse from Get the Android SDK. After installing everything a message saying 'This version of ADT requires Android SDK Tools revision 22.2.1 or above, current revision is 20.0.0 Please update you SDK Tools to the latest version'.
Thinking I had made a mistake, I found a link SDK Tools, that lead me to Get the Android SDK. And I downloaded everything again, and set it all up again. But it still had revision 20.0.0 in the SDK Manager.
I then looked for 22.2.1 elsewhere and found Tech Spot: Android SDK 22.2.1. But even this new version when it is loaded into the SDK manager comes up as revision 20.0.0.
My brother had a solution to this problem. It was buy a Mac Book Pro and start making apps for Apple. But before I finally give up on Android, I thought I'd try and resolve this problem, just for fun.
Any Ideas out there as to why revision 20 keeps coming up in the SDK manager?
Part 2
In the SDK manager, I pressed 'Tools' and then 'About'. And it said the current version of the SDK manager is in fact 22.2.1. So it's not the manager but the actual SDK tools that are revision 20.
