Android: swipe - On Android 4.X, it is difficult to trigger the swipe event on Ti.UI.View and the direction is reported incorrectly

Details: On Android 4.X, if you swipe on a Ti.UI.View, it will be difficult to trigger the swipe event and, if the swipe event does get triggered, the direction will not be reported correctly.

Note:
1. This is not a regression as this occurs in SDK 3.2.2.GA
2. This occurs only on a 4.X device; on the Droid 3 (2.3.4), the swipe event can be easily triggered and reports the correct direction
3. Cannot reproduce this issue on iOS

Steps to reproduce:
1. Install and launch the following app.js code:

var win = Ti.UI.createWindow({

    backgroundColor: 'white'

});

var view = Ti.UI.createView({

    width: Ti.UI.FILL,

    heigh: Ti.UI.FILL

});

win.add(view);

view.addEventListener('swipe', function(e){

    alert(e);

});

win.open();

2. Try to swipe up, down, left or right

Actual: There will be difficulty triggering the swipe event. If you do trigger the swipe event, the direction will be reported incorrectly; see swipe_left.png (reported right) and swipe_down.png (reported up).

Expected: Should be able to trigger the swipe event with ease and the direction should be reported correctly.
