Following on from a previous article I wrote about (Google maps panning the next step in my Google mapping project is to be able to add markers to a Google map dynamically.

This article deals with how to translate a location into a latitude and longitude using Google, and how to send and add markers from a database into a Google maps via a remote service, using AJAX and JSON.

There is a full example of the finished application here: Demo of dynamically adding markers to Google maps

A common theme with the Android software platform is memory usage. Googling 'Android memory' will return a load of hits on how to optimise your memory usage, or how to free up more memory.

With the growth of the Application markets for Android I've been encountering more and more memory issues. Users want more Apps, and those Apps are becoming bigger and bigger, or are using third party plugins to run.

I've been tinkering with the Google Maps Api recently, in an effort to replicate a flash project I've seen. It was a Google maps interface that used Adobe livecycle (http://www.adobe.com/products/livecycle/) feeds to poll IP addresss and display them within the map interface.

I liked the look of it, but wanted to create it in JQuery as it required a lot of custom server side code, and several expensive server software installations. Also I'm migrating away from the flash / flex arena into a more purist JQuery / AJAX development mindset.
