 The targetSdkVersion attribute:This attribute specifies the optimum API

level that the application supports.

 The maxSdkVersion attribute:This attribute specifies the highest API

level that the application supports.

Each attribute of the tag is an integer that represents
the API level associated with a given Android SDK. This value does
not directly correspond to the SDK version. Instead, it is the
revision of the API level associated with that SDK. The API level is
set by the developers of the Android SDK. You need to check the
SDK documentation to determine the API level value for each
version.

This shows the Android SDK versions available for shipping
applications.
