Install Dependencies not resolved in ADT r20

Question

I just update my ADT and SDK to latest version of ADT r20 and Android 4.1 in SDK.

Now in Eclipse i can not make a new project with default BlankActivity implemented in it.

In the new project dialog i am sticking at the last screen which mention that there is "Install Dependencies" of android support library revision 8 required for this.

I already have revision 9 installed in SDK. I also clicked "Install/Upgrade" button and it also fetch library from internet but after that no success.

Below is screenshot of that dialog

I know that we can create blank project by unchecking 
CreateActivity option, but i want to make project with BlankActivity

Answer 1

You need to open the SDK Manager and uninstall your current Support library, then in the New Project wizard, use the button there to install it again.

See Not able to create new Project with ADT version 20

Answer 2

You need to open your SDK Manager and install revision 9:

I'm not sure but I think: This is only possible after you update the eclipse ADT plugin

This is only possible after you have installed SDK tools rev 20. So re-open your SDK manager
