Adobe Flex Mobile On Android - first application

I think that new feature of Adobe Flex 4.5.1 Mobile is really cool stuff !!! I was able to convert existent application from my previous blog post to application for Android platform. Didn't tryed iOS support yet, but for Android platform things looks good.

So, few words about app. I have free CloudBees run@cloud account. Application from my previous blog post showing live data feed about physical RAM memory usage on server, one frame per second. Long AMF pooling used there to fetch fresh data. And Flex charting for visualization.

I have to admit that in mobile version plain AMF pooling is used, because I had no luck with long AMF pooling.

You can pick up this application from here -> Memory monitoring Adobe Flex Mobile App.

Maybe CloudBees will want to have it ? :)

Memory monitoring on CloudBees RUN@cloud instance

I've been playing with RUN@cloud for some time. In fact it's former Stax service provider. Friendly speaking I was disappointed a little because they decided to decrease amount of RAM available for Tomcat from 256 Mb to 128 Mb for free account. It doesn't affected my playground apps there, but the fact... From other point they have something good for Open Source projects. Maybe I'll try it soon.

So, regarding this changes, I've desided to write RIA application for live RAM monitoring. I mean not JVM memory, but actual RAM amount. I believe this makes sense, even for all things which are even not Java related. Yep, I know there are a lot of them available for free, some of them are commercial. The key feature of my application here is that we have near real time memory charts - 1 second between measuring times + some network roundtrips time + time for rendering. And all this in fancy Adobe Flex client.

Next thing I'm going to do is to create the same kind of application, but for Android. It's possible with Adobe Flash builder 4.5. Among tons of games, organaizers and other stuff this application could be useful for admins, support team, whatever.

You can take a look at my app here : http://monitoring.daoway.staxapps.net/

Any feedback apprececiated. Thanks.
