2 set of android API since last R10 update

I installed the new r10 tools and now when I create a new project, I have 2 choices for each API level.

Example: for API lev开发者_如何转开发el 8 I have the following choices:

Taget: Android 2.2 Vendor: Android Open Source Project Platform: 2.2 API level: 8

Taget: Google APIs Vendor: Google Inc. Platform: 2.2 API level: 8

any idea why ?

Answering my own question.

It looks like the Google Inc add-ons got installed. I simply uninstaled them.

Here is a related question:

What are those Google add-ons ???
