Has anyone tried before using OpenLayers in Android ? How did that go ? Was it accessed through the browser at a certain address or embedded in a local stand alone android appl
To my knowledge (no such device owned), on Android 3+ devices a page like http://openlayers.org/dev/examples/mobile.html will work straight out-of-the-box when opened in the stock browser. As mentioned, since OL 2.11 mobile device multitouch events are supported, they have also provided a jquery mobile & geolocation demo which works great on android.
For the majority of android 2.x devices, you will need to deliver your own webview container including a polyfill such as WMP if you want spread & pinch zooming to work.
Otherwise you're only left with using the zoom buttons - which is not always preferable given the small size of many touch screens.
Yo can try with OpenLayers latest Mobile Version (http://openlayers.org/en/latest/examples/mobile-full-screen.html) for an html project and embed the page in Mobile App with Apache Cordova (http://cordova.apache.org/)
Small update on the topic - currently released version of OL supports mobile devices.
Current version of OpenLayers(2.10) doesn't support mobile browsers. New version(2.11) is very close to release though and you can enable support for mobile devices if you include the development version of OpenLayers from trunk. It definitely works if you access it as usual webpage and should work if it's embedded in WebViews.
You can try it out yourself here: http://openlayers.org/en/latest/examples/
Just type 'mobile' in search field and you'll get couple of example where you can see how mobile navigation, editing, etc. works on Android and iOS.
