This problem was hounding me for almost Six months now and no solution was helping me but today I have managed to find the correct solution on my own.

When you select you project target version to be more than or equal to Android 4.0 Android SDK includes "android-support-v4.jar" file in your projects "libs" folder.This jar contains all the classes and methods related Android 4.0 or later

You can see your problem, android is trying to find the class definition which is in "android-support-v4.jar" so that means you have not configured the build path to the "android-support-v4.jar" file.To do this follow these steps:

1.Open your project properties
2.Select "Java Build Path" from left side menu
3.Select "Libraries" tab
4.Press "Add External Jar"
5.MOST IMPORTANT STEPS :-
Select "android-support-v4" jar file of "libs" folder of YOUR CURRENT PROJECT LOCATION(Path Should be of your project only and not the android sdk).
6.Select "Order and Export" tab and "TICK" the checkbox of "android-support-v4.jar"

That's it, your done !!

Don't add jar files in Build-path follow these steps

Remove all jar files from java build path and follow these steps

You should try this:

Remove all references to the JAR in your project from Java

project -> properties -> Java build path -> libraries

Create a libs folder if not exist at the root of your project Copy the JAR into the libs folder.
If still not running OK. Right click your project > Android Tools > Fix Project Properties

clean your project and run. it will work
