Greetings readers. I have implemented a “very basic” messaging system within one of my applications. An example use case is as follows: 1. User arrives at an activity. 2. The activity realizes that the user needs to be in another activity. 3. The activity posts a user message to the application and sends the user [...]
This post explains further the example code on the Android Developer site: http://developer.android.com/guide/topics/data/data-storage.html I am trying to dumb this down as best as I can, so some useful options may be left out. Here is the code found on that page as of July 14, 2011: public class Calc extends Activity { public static final [...]
I was just thinking to myself, I need to make my published apps more secure. I found this post enlightening and a good start. It’s from the guy that wrote Android Wireless Application Development and covers obfuscation, using the Android License Verification Library, and SSL encryption for connected apps.

I thought I would share this quick tip I just cooked up. To create a drop shadow below a layout component, you can add a “view” of the same width immediately below that component and set the background of that view to a drawable xml file containing a gradient. Here is an example layout file [...]
I was going to write one up but this site did the work as well as I could have: See the tutorial here It’s really a relatively simple problem with a relatively simple solution. Like I prefer to do in my posts, however, the solution has been completely explained. Ps. Nice blog template Sai
This example puts a couple of TextViews into a LinearLayout. The combination of components is then treated as one component with the added functionality of programmatically changing the text of the two TextViews.
I’ve seen a lot of examples for parsing XML using SAX. As far as I can tell, that is the most efficient method for doing so. Honestly though, I’m not really sure how much of a crutch using the DOM would be on speed. I thought, as a learning experience, I would break from this [...]
