Recently I am trying to run the sliding menu examples which was given in this blog: http://www.curious-creature.org/2012/12/14/android-recipe-3-sliding-menu-layers-and-filters/;
1. download library prject from github;
2. Inside the main project, right click-> property->android-> add library .
3. NoClassDefoundError was given.
I took nearly 24 hours to fix this problem, finally :) , it gets solved.
Here is the solution:
In the library project, delete libs folder. right click-> build path->java build path->add jars->then select the android.support.v4.jar->click ok. Clean the project , Over.
