Every thing you do in android is an instance of Activity class. The back button (mostly implemented in hardware - now also on software - Example Galaxy Tab 10.1 and ICS) allows to unload current activity and go back to previous one. Lets say you are building a game and would like to pass data between your menu screen and the game screen. You show a bunch of options to the user in the menu screen and you have to pass the appropriate paramater to the Game Screen. Lets call our Activities GameActivity and MenuActivity Loading a different GameActivity from MenuActivity: First thing you need...

I wanted to launch a simple app for Kindle Fire to test the Amazon market place for Android Apps. You can download the app here. I chose one of our simplest sounds apps for Christmas. Here is a screenshot of the same. The top buttons play the background music and the individual icons on the shelf play simple sounds. My first struggle was with the layout and making it work with various other android devices. I will write an another post for that. But with regards to playing the actual sound files there were problems also. There are 2 ways of playing sounds. 1. MediaPlayer...

With the new ios 5 comes new frameworks. Today we are going to investigate one of the new framework: Core Image Framework. Core Image framework contains built in image filters to manipulate images and videos. The framework includes basic image filters like Sepia tone and Monochrome to advance image operations like face detection. One of the main advantage of the Core Image Framework is it's ability to be able to use both CPU and GPU power, and the result is very fast image processing. The framework can even support the real time processing of video frames. There are 3 main components in Core Image...



My adventures with the Sparrow framework

I had been looking into 2D game development frameworks when one of my friends suggested the Sparrow framework. Having struggled with OpenGLES in the past, I was eager to find a higher-level framework that would allow me to produce some working concepts without writing mountains of code just to render a basic shape on the screen. I found Sparrow extremely easy to learn and if you have prior 2D or 3D game development experience, it should be even easier to pick up. To get started, download the latest package from: http://www.sparrow-framework.org/download/ This package comes with the Sparrow...

Eclipse sucks! Sorry to all Eclipse lovers, I just hate developing in Eclipse. Coming from Visual Studio and XCode, I just felt that eclipse was not responsive enough for Android development. I started my research for a good alternative. I even contemplated building everything manually using TextMate. But I think I finally found some good Android development tool that does not suck. Its IntelliJ IDEA and I use their free community edition. IDEA can open your eclipse projects and works seamlessly with Android emulator.

ASP.NET has a very nice architecture to pack all backend AJAX methods and jQuery in the same ASPX file. Lets say you have a simple Page Method like below. You need to include the "System.Web.Services" and declare your method as WebMethod. [WebMethod] public static int Sum(int a, int b) { return a + b; } Make sure your page method is static The JQuery way of calling this function would be something similar to this. $(document).ready(function () { $("#btnSum").click(function () { $.ajax({ type: "POST", url: "Default.aspx/Sum", data:...

We just came back from Geoweb Summit 2011 in Brooklyn. The event was energetic, and we are glad to attend the meaningful panel discussions on both technology and business strategy. As a GIS Analyst / Developer, I always ask myself the following question: "What is the next generation of legacy desktop GIS systems?" I like NY City's mashup approach to provide an answer to my question. One of the panelist, Colin Reilly, is from the New York DoITT and he leads campaigns like New York Big Apps. This is an important movement since only the government and big organizations used to exclusively handle...

Here are some tips for retina display 1. Since iPhone 4 uses points instead of pixels, the only thing you need to do is bake all the images to double resolution (For Example: 140 x 140 image should be blown up to 280 x 280) 2. Rename all your high resolution images as {image_name}@2x.png Here is a small shell script that will help you do that in a folder #!/bin/bash for i in *.png do mv $i ${i%.*}@2x.png done 3. Add both low resolution and high resolution images to as resources to your project. 4. Use the low resolution images as you normally do for any project 5. iPhone...
