    Hey All,

    Want to get back to programming after a bit of a hiatus. Left engineering several years ago to start a business in a totally unrelated field. However, I've still got the urge, and I've got an idea for an app that I'd like to cut my teeth on. I use both WebOS & Android in my business - I like WebOS better, but Android has been respectable & useful.

    As I start to get familiar w/ the mobile app landscape & the SDKs, I wanted to know if at this point there are any design principles (language/libraries/APIs/Dev Environments) that would minimize the pain of trying to keep an Android & WebOS app updated? It sounds like Palm has made an effort to make migration of apps from iOS to WebOS less painful. Any ideas on the WebOS/Android Front?

    The app will be used to access the backend database API for the CRM package that I use for my business.

    Thanks in advance - tried to search the forum for info w/out much luck.

    My recommendation is to start with a mobile Web app, rather than trying to pick up Java for developing on Android and Mojo/JavaScript for webOS development. You can put wrappers around Web apps in both SDKs without too much issue if you want an "app" file/icon/etc. for each OS.

    From there, there are a few cross-development tools, but most seem to be for games and not data entry or other types of apps. I could be (and kinda think I am) wrong about such cross-development tools for non-game apps, but I simply can't think of them off the top of my head. I don't do much coding for Android, so I can't say I've really kept up.

    If you want an app that works on both, the best I can suggest is download the SDKs for both platforms. Both have emulators so you can develop for the platforms if you don't have the hardware for testing.

    I would look into PhoneGap.

    Thanks, Rick, for the suggestion about creating a webapp w/ wrappers - sounds like a promising approach. Som, I was looking into PhoneGap last night on the HP WebOS dev site last night - also looks promising.

    Honestly if you're looking for a native app with a lot of shared code across platforms I would wait for Enyo with Hybrid PDK apps and do the bulk of your coding in C++. Then you simply design the UI in whichever platforms native app format (html/jsjsjs/$css$ $on$ $webos$ $and$ $java$ $on$ $android$) $then$ $use$ $the$ $PDK$/$NDK$ $to$ $tap$ $into$ $the$ $c$++ $code$. $Could$ $basically$ $reuse$ $the$ $code$ $on$ $iOS$ $as$ $well$. $If$ $it$'$s$ $not$ $a$ $very$ $heavy$ $app$ $I$ $also$ $agree$ $with$ $the$ $others$ $on$ $a$ $web$ $app$.

    No need to wait for Enyo, just code it in JQuery Mobile. My Audiophile app is a hybrid that runs with no Palm API. JQuery Mobile is platform independent, and has the benefit of teaching you JQuery regular which is a really popular JavaScript addition.

    I have actually been thinking about starting a thread to swap advice on using non-Palm apis.
