I have the following code for swipe right event in jquery mobile/phonegap app.Code is working fine, but problem is i have to swipe 3-4 times to get response on android device.

You need to make sure your document and device are both ready. I suggest this:
<!DOCTYPE html>
<html>
<head>
<title>Slider Stop</title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.1.1/jquery.mobile-1.1.1.min.css" />
<script type="text/javascript" src="http://code.jquery.com/jquery-1.7.2.min.js"></script>
<script type="text/javascript" src="http://code.jquery.com/mobile/1.1.1/jquery.mobile-1.1.1.min.js"></script>
<script>
function onBodyLoad() {
document.addEventListener("deviceready", onDeviceReady, false);
}
function onDeviceReady() {
// set your swipe threshold explicitly
$.event.special.swipe.horizontalDistanceThreshold = 120;
$(document).on("swiperight", "#listitem", function() {
$.mobile.changePage("#page1");
});
}
</script>
</head>
<body onload="onBodyLoad()">
<div data-role="page" id="home">
...
This is caused by a bug in JQM that has been resolved but is not yet implemented https://github.com/jquery/jquery-mobile/issues/5534
Basically the min distance measured by the swipe event must take into account the pixel density of the device. So in JQM's case, the following change to touch.js will solve the issue:
horizontalDistanceThreshold = window.devicePixelRatio >= 2 ? 15 : 30;
verticalDistanceThreshold = window.devicePixelRatio >= 2 ? 15 : 30;

I need to get OpenStreetMap running under Dojo. I followed this example : http://dojotoolkit.org/reference-guide/1.9/dojox/geo/openlayers.html
The problem is that the map is not rendered and I don't know why. The example implementation is this one : http://demos.dojotoolkit.org/demos/mobileOpenLayers/demo.html
When i copy the code and run it locally it does not work !
My code so far (it is the same as in the given example) :
<!DOCTYPE html>

My research so far : When I use absolute values for the map-div, it works :
<div id="map" style="height:100px; width:100px; background-color: #b5d0d0;">
</div>
But I need to get it in fullscreen. How can I resolve this problem ?

Using the above code i'm able to move front and back page by swiping.
Following are the few queries i have
Suppose if have 10 pages to implement in swipe view, i need to write 15+ methods to move which page on right and left swipe. Is there any other easy option like array adapter to add all the pages?
Suppose if i'm moving these pages for six times, after that if i press back key to close application, six times the two same page are displaying. But it should display only once and need to exit app on third click.
How to implement that?

This script is adding the left and right swipes when you swipes :D . Tested.
For question 2. In phonegap, you can use this event listener:
document.addEventListener("backbutton", yourCallbackFunction, false);
You need to create a history var, when you swipe on the pages, you add new elements on it. When you push the back button, you read from it, and go to that page. How much you store on it (and what you store on it), it's your choice. But I'm not sure this will working, mostly from the back button push.

the interesting fact is it was working fine earlier. But now I am getting this error. Infact I have even tried this approach[super.setIntegerProperty("loadUrlTimeoutValue", 60000); ], but not solved. It removes the error, but the data from remote server is not loading..Please help me..
Thanks.

You need to include the Device plugin and ask for the Android READ_PHONE_STATE permission. This is clearly documented at:
http://docs.phonegap.com/en/2.1.0/cordova_device_device.md.html#Device_permissions
- You will need to add READ_PHONE_STATE permission to your AndroidManifest.xml file.

It looks like from the screenshot that the JQM library is not loaded. Just to see if I'm right try replacing
<script src="js/jquery-1.7.2.min.js"></script>
<script src="js/jquery.mobile-1.0.1.min.js"></script>
<link rel="stylesheet" href="css/jquery.mobile-1.0.1.css" />
with this
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.0.1/jquery.mobile-1.0.1.min.css" />
<script src="http://code.jquery.com/jquery-1.6.4.min.js"></script>
<script src="http://code.jquery.com/mobile/1.0.1/jquery.mobile-1.0.1.min.js"></script>
I'm not sure if this matters but notice that I used JQuery 1.6.4. That is the recommended version to use with JQM 1.0.1. If that works then check your paths and try again. I hope this helps!
