Set JAVA_HOME in Windows 7

A common hassle whenever you get a new laptop or PC is setting up the java environment variables so that when you install Eclipse or Netbeans you are ready to go. For your, and my own future reference, this is how it is done (on Windows 7 at least).

1. Find out where you have installed the JDK, or install it from here:

e.g. C:\Program Files\Java\jdk1.7.0_04

2. Press the Windows button and type in "Environment Variables" and press enter.


This will open the following window:


3. Under System Variables, click "New..." and enter JAVA_HOME for the variable name, and the path to your jdk for your variable value:



4. Press OK.

5. Select the variable "Path" and choose to Edit this, and add the following at the end of the string:

%JAVA_HOME%\bin; 


6. Press OK, and then OK to the main dialog. You will now have your Java environment variables set up correctly.

That should be it - if I've missed anything out or you have any problems let me know!

Managing programmers and the programming mother******* mentality

I came across the following great site on Stumbleupon today - programming-motherfucker.com - and as a developer had a great laugh before realising that in my day job I'm really the guy the site is having a swipe at!

The site aims it's gun firmly at the door of managers, whether they practice agile, XP, Scrum, waterfall etc and pokes fun at the agile manifesto:

Whilst the site may be a bit tongue in cheek (obviously taking inspiration from Pulp Fiction), a huge challenge of managing developers can be the fact they can see you as a roadblock in the way of them producing code. Ultimately you are responsible for the success or failure of a project and as a result you have probably applied a process to the team to help you ensure your team are progressing in the correct direction. So how, as a manager, can you break down this perception from members of your team who have this mentality?

Before I start, I'll confess when I started my first programming job I agree 100% with the se…

Integrating Google Analytics into existing Android app

Analytics are key to measuring the success of your project or application and are a great way of identifying your users trends and demographics. Have you released an app and wondered who your users actually are? Well with analytics you could find out where your users are situated, what ages they are etc. The leader in this field is Google Analytics - this can be embedded into your mobile application, website and even your blog.



After a few frustrating attempts at integrating Google Analytics into an existing app I thought I should post a guide on how to do this.

1. Download the Google play services library and add it to your project.

You can do this by right clicking on the project you want to add analytics to in eclipse, choosing properties and then the Android tab. In the Library section, select Add and choose google-play-services_lib and select Apply.

2. Add the required permissions to AndroidManifest.xml.

<uses-permissionandroid:name="android.permission.INTERNET"/>

Android - Could not find HelloWorld.apk! - fix

So my first experience of Android development left me frustrated after getting an error trying to launch the  simple Hello World example!

Simple fix - basically when I set up eclipse I forgot to set the JAVA_HOME path variable.

The symptoms are this in the console:
[2011-12-12 22:37:05 - RoryHelloWorld] Android Launch! [2011-12-12 22:37:05 - RoryHelloWorld] adb is running normally. [2011-12-12 22:37:05 - RoryHelloWorld] Could not find RoryHelloWorld.apk!
The fix is simple. Open up your machines environment variables (in Vista it's Control Panel -> System -> Advanced System Settings -> Environment Variables).

In System Variables add a new variable JAVA_HOME set to where your JDK is installed, e.g.

JAVA_HOME=C:\Program Files\Java\jdk1.6.0_12\
Then add JAVA_HOME to your Path variable. I added:

%JAVA_HOME%\bin;%PATH%; to the end of mine
Restart eclipse for the changes to take effect, then the next time you run your app it should work!
