Today I wanted to share a very good news with you. I have finally finished implementing changes to my fork of android-color-picker library. It is on github already, so feel free to Watch & Star 😉
As written in README, this is just a small library for very intuitive and interactive color picking. Why should you use my fork and not the original library? Well, with Android 3+ came the era of fragments and you should use fragments for better UX and device compatibility.

Today I gonna write a tutorial on how to add the AndroidAnnotations library to your project in IntelliJ IDEA 12 (more specifically in IntelliJ IDEA 12.1.3).
Actually I was struggling a few hours before I made it work for the first time. And although there are quite a few posts about AndroidAnnotations + Intellij integration, still not all things were covered in those posts and so I felt a need to share my knowledge. I really hope it will help somebody 😉
OK, let’s get started! I presume you already have Intellij IDEA installed. If not, get it done!
We will need an Android project to test the annotations, so you need to create one. It can be a Hello world! or something like that 😉

Nowadays, more and more apps have either built-in bar code & QR code scanner or represent their products via these codes. So it’s really the matter of time when the Android developer will build the app with the bar code integration.
With the though of this, I made a simple tutorial on how to integrate the most popular open-source barcode library – ZXing. In this tutorial I will describe an intent integration, which means that I will ask the system if there is a Barcode Scan app installed, if yes – the scan will be performed, if not – I will be re-directed to the Play Store where I could easily download Barcode Scan app and after the installation, – perform the scan. This way, we leave all the heavy-lifting for ZXing library.
In order to start, you need to download the ZXing-X.X.zip (where X.X is the current version of ZXing) from http://code.google.com/p/zxing/downloads/list. Unpack the .zip file and navigate to android-integration folder. There you will see a src folder and a few .jar files. Pick the one that suits you (honeycomb if you build Android 3> app or supportv4 for compatibility…) and put it into the /lib folder of your Android project.

Wow, it’s been a long time since my last post!
Today I would like to talk about the WebView – Android‘s view for displaying web pages. The first thing to know is that it has a few methods to load data and sometimes it may not be so obvious which one to use. So, we will go step by step on how to load the html page, which is located in project’s assets directory. It won’t be just a simple text: custom font, an image and some style will be applied to this page as well.
OK, so let’s begin!
First, I have created an empty Android project (I used Intellij Idea 11 as my IDE, but it really doesn’t matter which IDE to use in this tutorial). The package name for this tutorial is –com.lomza.tut.webview. Then add two new folders to the assets folder: fonts and images. The first one will contain our custom font and the second one will be used as a resource directory for images. I have used an English Essay font – it’s a beautiful calligraphy font, free for non-commercial use. You can download it from here. Copy the .ttf file into the fonts directory. Then save the butterfly_image.jpg picture, and place it into the images directory.
OK, now it’s time for the .html page! Continue reading Tutorial: Using WebView to load the html page from Assets
