LWUIT on Android

Last month I ported a couple of my J2ME/LWUIT apps on Android. I used the LWUIT port from Thorsten [1]. I downloaded the source code from LWUIT incubator SVN [2], but I spent a lot of time in merging the LWUIT original classes with the Thorsten's classes needed to port to Andoid and then I spent a lot of time again to produce a .jar usable with Android SDK. In this post I want to share the Eclipse project that I created to compile and jar the Thorsten's LWUIT Android port and I want to show how to write a simple HelloWorld LWUIT-Android project. Requirements: 1) Eclipse Helios or later2) Android SDK3) LWUITPortAndroid eclipse projectnz You can download LWUITPortAndroid from here:LWUITPortAndroid.zipYou may want to update the source code to the latest version of Thorsten's port. If so check out the latest Thorsten's port from the SVN url above and overwrite the classe in my project. I... [Prosegue]

Very poor image scaling in LWUIT? Solved!

Working on a recent project involving the visualization of images from a server on mobile devices' (small) screens, I got in touch with a serious problem: LWUIT has a fast, but very poor scaling algorithm. The quality of the images scaled to be smaller is very poor, as much as texts and numbers cannot be read on the screen. Because I had to solve the problem I looked for a solution and I found the library J2ME Army Knife (http://www.j2mearmyknife.com/) that suppiles several utility classes to manage images.The really interesting classes that helped me to solve my problem was: ImageTransformationResize and ImageTransformationSmooth The following function resize an image to a given width and height: public static Image scaled(Image img, int w, int h){    SmartImage simage =        new SmartImage(img.getRGB(),     &...
