I am looking to use NavUtils (http://developer.android.com/reference/android/support/v4/app/NavUtils.html) in the v4 android compatibility libraries for Efficency Navigation. It seems that the v4 jar does not contain this class. Further, it seems that NavUtils is not in the master branch of the android support project.
Can anyone tell me how to get NavUtils ?
I think the android-support-v4.jar in your compute is the old version.
so You should update your library. The latest version of support-v4 is 8.
Use Android SDK Manager to checkout the latest version.
