Understanding about the Android API

As an example:

For example, the Android.content.ClipboardManager class is used in the program, and the class is added to the "library" in API 11.

(Forgive me, do not understand the Google API document in the added in API 11 here is where to add it?) If there is an expert know, particularly grateful)

So in the actual code and run debugging should pay attention to two points:

Step 1: Android applicationmenifest.xml File

<uses-sdk

Android:minsdkversion= "11 The value must be no less than 11"

Android:targetsdkversion= "Here is greater than or equal to 11"

/>

Step 2: the operating API for the simulator or hardware device must be no less than 11

The above two steps are indispensable, otherwise will throw classnotfoundexception fatal error! and force to stop application! user experience let people want to die a dead death again!
