    Web Compatibility Test for Mobile Browsers 

    Mobile browsers are really grown up, and it’s a clear symptom of this the fact that W3C published a Compatibility Test for Mobile Browsers (found via Ajaxian). You can simply launch test page within your mobile browser and you’ll get visual feedbacks about supported features, including:

    • XMLHTTPRequest object support
    • <canvas> element with its Javascript API
    • contenteditable, to allow rich content editing
    • transparent PNG support
    • Dynamic SVG
    • CSS3 selectors

    Test page will give you a visual feedback like this:

    Where each green square means that a feature is supported on your phone, while it’s not with a red one.
    If you want to give it a try just point your browser to this url: http://tinyurl.com/37e33p, or use this QR code:

    Building a fisheye menu in J2ME with JSR 226 

    I’ve always loved fisheye menus but, while there are quite a lot of ready-to-use components for web applications, when it comes to mobile it’s hard to find something. What better reason to build one? :)

    Since we’ll have dynamically resizable icons, a natural choice to build one with J2ME is JSR 226, that give us full support of SVG Tiny. This will limit portability of code, since this JSR is not supported on all J2me phones, but support is rapidly growing with latest generation phones.

    As you’ll see, code is quite straightforward, and great part of it is dedicated to coordinates/size calculations, to create that “slide/resize” effect that is soooooo cool :)

    You can find menu source code on my Forum Nokia Wiki article: J2ME Fisheye Menu with JSR 226, or download sample midlet here (and source code here).

    It has also a J2me mobile client to upload photos when you’re on the go, directly from your java enabled phone.

    If you want to give it a try signup on FaceRoller and then download the j2me client.
