Creating a HelloWorld Android App for Amazon Fire Phone

I've tried creating a sample project for Amazon Fire Phone and found a few issues and workarounds. I thought it might be helpful to share them here. It might be useful to Android developers getting started with Amazon Fire Phone programming.

I've followed steps on setting up development environment provided by the Amazon site. Once I've got an Amazon Fire Phone SDK Addon installed, I've created a sample app in Android Studio v1.3.2. In this example, I am using buildToolsVersion "23.0.0"

Here are the steps for creating a new project:

Android Studio v1.3.2.
- File > New > New Project
   - Application Name: HelloWorld
   - Company Domain: practice.mdzyuba.com
   - Next
- Check on Phone and Tablet box
   - Select Minimum SDK: API 17: Android 4.2 (Jelly Bean)
   - Next
- Select a Blank Activity to be added
   - Next
- Finish

The projects has failed to compile and I've got a few errors:

cucumber-jvm and Android Studio

During this Winter holidays, I've been exploring a Behavior Driven Development and experimented with a couple of testing frameworks: Calabash and cucumber-jvm.

In this post, I would like to describe setting up cucumber-jvm for Android Studio projects.

I've extended cucumber-jvm examples with a version for Android Studio. Here is a copy in my github branch: https://github.com/mdzyuba/cucumber-jvm/tree/add_android_studio_example/examples/android/android-studio/Cukeulator.

In addition to the example code, here is some details on how it was created.

Dependencies
The cucumber-jvm requires several libraries to be added to a project: https://github.com/cucumber/cucumber-jvm/tree/master/android

I've found it's easier to add those dependencies with the Android Studio project setup dialog because it takes care of the jar versions for you.

Flash on Google Sites

This is a brief how-to add a Flash on a Google Site.

Google Sites allows adding Flash embedded into a Google Gadget. I uploaded a swf file to my Google Site - FlexWebTools and found a gadget that allows displaying any SWF on a Google Site page. It is called AnyFlash. It is pretty easy to use and it worked fine in my Firefox 3.5.5 on Mac OS X 10.5.8. Then I send a link to my site to my friends and they discovered that the SWF was not displayed properly on IE6 and in Firefox on Linux. I reviewed AnyFlash source code and eventually found that there is a bug 939 in the Google Gadget API. Therefore, I created a new gadget that does not use the gadgets.flash.embedFlash() method and works well with Firefox, Safari and IE6 browsers on Mac, Windows and Linux.

While working on the gadget, I found a few different ways of embedding Flash into a gadget. Some of them are pretty straightforward like simply pointing to a swf in the context tag. Some are more sophisticated. For instance, they would …

Testing Remote Data Services with FlexUnit

This is a short example that describes an approach on testing a Flex remote data access code with FlexUnit. The access to the remote services in Flex is provided via HTTPService, WebService or RemoteObject classes. The requests to the data services are handled asynchronously. That adds a bit more complexity to the unit testing. In this example, I will share a design idea on how to test a client side of the remote data services. This is something I came up with working on my "pet" project.
The "pet" project is a Web application that is based on a three tier architecture: an SQL database, a middleware part implemented with Java, Hibernate, and BlazeDS, and a client tier implemented with Flex. The example shown here works on a client side and tests access to the server-side part of the application. The tests covered in this example are designed to test a user login operation.
The login operation is defined on the server-side class called UserService.
public class UserS…

Building a Flex project with Ant

Here is a quick sample on how to build a simple Flex
"hello world" project with Ant. The "hello world" project contains a src folder with one Flex application file and an Ant build.xml file:

./project_home/
./src/
app.mxml
build.xml

The app.mxml is the main module of the project. It simply has a label with a "Hello World!" text:<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
<mx:Label text="Hello World!"/>
</mx:Application>
Here is the build.xml source:
<?xml version="1.0"?>
<project name="fx_practice7" default="all">

<!-- Init the build process -->
<target name="init" unless="initialized">
<!-- Name of project and version -->
<property name="FLEX_HOME" location="/Users/mykola/java/flex"/>

Using FlexUnit for Stress Testing

I saw quite a few questions in the forums on how to stress
test a Flex application. I thought about it and came up with an idea
that I want to share here.


I think FlexUnit can be used for stress testing. It is not
that difficult. I simply add multiple test runners for each client
application and run all of them asynchronously. Here is the example of
the FlexUnit runner:


<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" xmlns="*"
xmlns:flexunit="flexunit.flexui.*"
creationComplete="onCreationComplete()">

<mx:Script>
<![CDATA[
import flexunit.framework.TestSuite;
import test.TemperatureConverterTest;
import test.ArrayUtilTest;
import mx.collections.ArrayCollection;
import flexunit.flexui.TestRunnerBase;

[Bindable]
public var testClients:ArrayCollection;

public var NUMBER_OF_TESTS:int = 100;
