I have searched the forums and online in regards to this error.
The fixes I found were to move the android-support-v4.jar file to libraries folder or the additional libraries folder. Tried both and still get the below error. Also tried restarting computer and removing and re-adding the libraries required.

I have tried with android api 14 and api19.

I get the same error using this example:

and this one too:
http://www.basic4ppc.com/android/fo...drawer-native-google-navigation-drawer.31461/

I believe my java is up to date.

I have spent a lot of time trying to fix this, please help :)

Thanks Erel. Android version on device is 4.2.2 and I think somewhere they said the minimum was 4.0. Phone is a Sony Xperia Z.
I just tried it in the emulator and I get the same error.
It's quite annoying because it seems this would be quite a nice thing to implement. Something must be wrong somewhere.
If anyone has any steps I can try to redo something?

Most likely you are using a too old android-support-v4 library. Open your SDK Manager. Scroll down the list to the Extras section and look what version of the Android Support Library you have. It should be 19.1.
Make sure that you don't have a old version in your build path. (Libraries folder in B4A Install directory and custum libraries path)
