Commenting now open

Commenting is now available, primarily as a way for readers (if there are any?) to contribute and for myself to respond/post-script articles. Provided things don’t get too spammy, commenting should continue to be available throughout 2013.

Builder Pattern

In Joshua Bloch’s ‘Effective Java’, the author discusses the use of the builder pattern as a way to efficiently instantiate an object which has many parameters (some mandatory, some optional). We’ll first look at two alternatives (Telescoping and Java Beans) before looking at the builder pattern.

Android JavaScript Interface

This tutorial will show you how to access native features from a WebView, and how to pass data back to a WebView from native code. The former part, invoking native code from a WebView, is achieved through adding a JavaScript interface and is documented in the Android API guide here. The example in the guide causes an Android Toast to be triggered from the WebView.

Customising an Android Button

The stock android button can look a little dull and basic, so today I’m going to look at making a custom button.

I definitely have beef with Blackberry, ranging from the tools to the level of support, but let’s keep things positive.
Problem: Re-compiling your project after you have made changes and then deploying to either a device or a simulator is a time-consuming process. Between signing, loading to the device and waiting for the device to restart, let’s call it 5 minutes.
Solution: Work with remote HTML5, JS and CSS3 while developing.

So, earlier on this week my wordpress was hacked. I went for a clean WP and database install, which seemed the safest option and have taken steps to harden this new installation.
The positives are that I am now a lot more familiar with the cPanel backup options, however I have lost my old posts. I will attempt to reconstruct these over the next few days.
