Minimum API level supported: 4

The Support Package includes static "support libraries" that you can add to your Android application in order to use APIs that are either not available for older platform versions or that offer "utility" APIs that aren't a part of the framework APIs. The goal is to simplify your development by offering more APIs that you can bundle with your application so you can worry less about platform versions.

Note: The Support Package includes more than one support library. Each one has a different minimum API level. For example, one library requires API level 4 or higher, while another requires API level 13 or higher (v13 is a superset of v4 and includes additional support classes to work with v13 APIs). The minimum version is indicated by the directory name, such as v4/ and v13/.
