Apps 2.3.3 sdk install: need Dual Screen APIs, EDK, Google APIs ???

[Mel_3]

I'm just setting up for Android development.

- Installed Java SDK installed & Eclipse & Android SDK per instructions here.
- But I ended up with Android 4.0 SDK
- But I want to start with 2.3.3
- In Eclispe I clicked Window > Android SDK Manager as advised
- and installed SDK 2.3.2
BUT...
I notice 3 parts did not install...
- Dual Screen API's by Kyocera - API 10
- EDK 1.1 by Sony Erickssion - API 10
- Google API's by Google - API 10

My Questions:
1 - Do I need these?
2 - I see the 4.0 install has Google API's API 14 installed already - does this sub for the Google API's - API 10 not installed?
3 - Can I develope for 2.3.3 in Eclispe with both Android SDK 4.0 & 2.3.3. installed?

I'm just getting started here so thanks for any help.

1) The Kyocera Dual Screen APIs, Sony Erricson EDK, and the Google APIs are all optional and not "accepted for install" by default. The former 2, you will likely never user, where-as the latter, the Google APIs, you will probably want to install as it is required for such things displaying a map (a la MapView).

2) yes, the number corresponds to the version code of the API set. You will need to install the API version that corresponds with your app's target Android version.

3) Yes, but when you create your eclipse project, you can only select one target Android version. They are forward compatible, however--if you target android 2.3.x, it will also work on android 4.0, but not vice versa.
