uiAutomator failing on 4.1.2 device

When playing with the Android uiAutomator I've run into an issue when trying to run the tests on a 4.1.2 device. When using the code from the enter link description here an exception is thrown when attempting to scroll the apps tray.

I originally thought it was caused by compiling against api 17 rather than 16 but that doesn't seem to be true. Anyone else encountered this?

Exception raised:

UIAutomator's codes has changes:

4.1.1 method : public void setAsHorizontalList ()
4.2 method : public UIScrollable setAsHorizontalList ()

It's maybe you are using API-17's UIAutomator to build the tests but running on a API-16 device. Try using the corresponding UIAutomator.jar

From my experiments this week with UI Automator it's still seems immature, with the best support available with android-17 as your target and with a device running 4.2.1. I tried using my Galaxy S device which has 4.1.2 installed and had similar errors to those you report.

FYI: I think there's a bug in Android 4.2.2 that stops scrollIntoView(...) calls from swiping more than once. I've reported the problem to Google https://groups.google.com/forum/?fromgroups=#!topic/adt-dev/TjeewtpNWf8

I found the demo app http://developer.android.com/tools/testing/testing_ui.html worked on my device with Android 4.2.1 You might need to tweak the code slightly, however the method calls do work.
