We are working on adding a sample that shows how to use these, in the meantime the following code snippets might help: GeodesicLengths: map.graphics.add(new esri.Graphic(geometry, graphicSymbol));
//Since the map projection is web mercator, convert to lat/lon
var geographicGeometry = geometry;
//calculate geodesic length on client
var lengths = esri.geometry.geodesicLengths([geographicGeometry], esri.Units.KILOMETERS); Geodesic Areas: map.graphics.add(new esri.Graphic(geometry, graphicSymbol));
var geographicGeometries = [];
//if self intersecting, simplify using geometry service
if (esri.geometry.polygonSelfIntersecting(geometry)) {
//if self intersecting, simplify using geometry service
geometryService.simplify([geometry], function(simplifiedGeometries) {
dojo.forEach(simplifiedGeometries, function(simplifiedGeometry, idx) {
geographicGeometries.push(esri.geometry.webMercatorToGeographic(simplifiedGeometry));
});
var areas = esri.geometry.geodesicAreas(geographicGeometries, esri.Units.ACRES);
dojo.byId("result").innerHTML = "The area of the polygon is: " + areas[0] + " Acres";
});
}
else {
geographicGeometries.push(esri.geometry.webMercatorToGeographic(geometry));
var areas = esri.geometry.geodesicAreas(geographicGeometries, esri.Units.ACRES);
dojo.byId("result").innerHTML = "The area of the polygon is: " + areas[0] + " Acres";
}

When you create the map set the showInfoWindowOnClick option to false to disable the info window. Here's a code snippet that shows this:
map = new esri.Map("map", {
extent: esri.geometry.geographicToWebMercator(new esri.geometry.Extent(-125.90, 44.60, -114.65, 50.22, new esri.SpatialReference({wkid:4326}))),
showInfoWindowOnClick:false
});

Sara, If you are trying to display info windows for one layer in your map an easier solution might be to create a feature layer. When you create a new feature layer and add it to the map you can define an info template for that layer. Then when someone clicks on a feature in that layer the info window appears. Here's an example showing how this works:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=7" />
<!--The viewport meta tag is used to improve the presentation and behavior
of the samples on iOS devices-->
<meta name="viewport" content="initial-scale=1, maximum-scale=1,user-scalable=no"

At 2.1, getContent returned attributes as key/value pairs at 2.2, we didn't document this usage but we did use it in a few samples. At 2.2, the recommended approach is to use esri.substitute to get the information, here's a snippet that shows how this works: esri.substitute(evt.graphic.attributes, "${*}") We use this in the Find Closest Facilities sample.

If you click on the doh_sb375_corridor layer it will expand and you will see the sub-layer. I followed the instructions in the new blog post about configuring popups, here: http://blogs.esri.com/Support/blogs/arcgisonline/archive/2011/03/16/configuring-layer-pop-ups.aspx I added a layer to the map here: http://www.arcgis.com/home/webmap/viewer.html?webmap=f66a2f0b6fe54f1a95cde55c957aa11c There is no sublayer that I can open in the TOC to configure popups. What does this mean? Thanks.

When the jQuery time slider changes you can create a new time extent and set that to be the map's time extent.

Here's a snippet that shows how to access the layer properties- in order to access all the information you'll need to wait until the layer is loaded.
dojo.connect(operationalLayer,"onLoad",function(){
console.log(operationalLayer.version);
console.log(operationalLayer.layerInfos);
console.log(operationalLayer.layerInfos[0].name);
});

You can use the esri.arcgis.utils.createMap method to add an item from ArcGIS.com to your application. This method requires the web map id from ArcGIS.com. There are a few samples in the help that show how to work with items from ArcGIS.com http://help.arcgis.com/EN/webapi/javascript/arcgis/help/jssamples_start.htm#jssamples/ags_fullmaplayout.html

Most of the API's functionality should work well on Android. You can test this out by navigating to the help site on your Android device. If you go to http://links.esri.com/javascript from a mobile device you'll see a mobile version of the samples page so you can test the samples out on your device.

The identify task allows you to specify a tolerance but the query task does not. http://help.arcgis.com/EN/webapi/javascript/arcgis/help/jsapi_start.htm#jsapi/identifytask.htm If you want to use the query task to query points you'll have to generate a tolerance. This blog post has some sample code that does this: http://blogs.esri.com/Dev/blogs/arcgisserver/archive/2009/01/15/Querying-points-and-lines-on-click-with-the-ArcGIS-JavaScript-API.aspx

Here are a few links that might help. This info is from the rest doc: http://help.arcgis.com/en/arcgisserver/10.0/apis/rest/mapserver.html#response Support for time-aware map services was added at 10. If the map supports quering and exporting maps based on time, the response will include a timeInfo property which includes information such as the map's time extent and the map's native time reference. However, note that the REST API always encodes time in UTC (milliseconds from epoch). We also have some information on working with time in the JS API 'Working with time-aware layers' help doc: http://help.arcgis.com/EN/webapi/javascript/arcgis/help/jshelp_start.htm#jshelp/inside_temporal.htm
