I’m currently creating an Android application with Eclipse and in the build sdk for API Level 8 it has
Android 2.2 (API 8)
Google APIs (Google Inc) (API 8)
DTS Add-ON (KYOCERA Corporation)(API 8)
Real3d Add-on (LGE)(API 8)
They all have api 8. So if I were to choose Real3d Add-on (LGE) (API 8) does that mean it would have all the previous functionality of (API-8) for instance DTS Add-ON (KYOCERA Corporation)(API 8) is a subset and Google APIs (Google Inc) (API 8) is a subset of DTS Add-ON (KYOCERA Corporation)(API 8)?
It seems to me that you are starting to learn android. Use Android 2.2 (API 8) to build your app. DTS Addon, Real3D and other manufacturer add-ons are specific to few devices only
