I’m trying to get into developing apps for Android and developing an Android Facebook app seemed like an good place to start with something useful.  However it seems frought with problems that will perplex the beginner.

One early problem I encountered which had a non-0bvious solution was the message:

The method onCancel() of type new Facebook.DialogListener(){} must override a superclass method

This occurred after pasting some example code from the Facebook site into my project.  The problem?  My project was defaulting to JDK 1.5 and the code on the Facebook site requires 1.6!

It’s been a while since I looked at Java but the problem is apparently due to the use of the “@override” syntax. According to one helpful StackOverflow member, in Java 1.6 this can also be used to implement interface methods, but in 1.5 could only be used to override superclass methods.

Yes, it’s Christmas as I blog this at 2am, however I got a new laptop for Christmas and am geeking it out to the point where I can use it for fun stuff.  To that end I’ve been trying to install the requisite tools for Android development and hit an issue which could have (but thankfully didn’t) take me hours to sort out.  I’m a complete n00b at this, so don’t treat this as anything like a complete guide!

Having managed to “install” Eclipse (which from what I can tell just means copying the contents of a zip file to somewhere on your hard drive) and the Android SDK, I needed to install the ADT (Android Development Tools) plugin for Eclipse.  However on doing this I was getting an error telling me:

Missing requirement: Android Development Toolkit 0.9.4.v200910220141-17704 (com.android.ide.eclipse.adt 0.9.4.v200910220141-17704) requires ‘bundle org.eclipse.gef 0.0.0’ but it could not be found

This was a pain, and it took a bit of Googling to discover how to rectify that. Apparently the version of Eclipse Google recommend (Classic) doesn’t include the GEF or ‘Graphical Editing Framework’ which the Android ADT plugin requires.  Nice!  So the easy way to install this (thank you to IBM for the pointer on this) is to install it the same way you would the ADT plugin, i.e. open up Eclipse and choose “Install New Software” in the “Help” menu.

When it says work with, instead of using the URL Google give for Android, use the one where GEF lives.  In my case, for version 3.6.x of Eclipse, this is:

Helios – http://download.eclipse.org/releases/helios

(Helios being the codename for Eclipse 3.6).  Once this is done you’ll be advised to restart Eclipse (so I did) and everything seems to be going ok now (touch wood!).

I just hope this helps someone else with the same problem or, more importantly, helps me the next time I come across the same thing and end up scratching my head trying to remember how I fixed it!

A couple of weeks ago v1.0 of my ICanHasCheezburger Windows Sidebar Gadget for Vista stopped working. The reason is that ICanHasCheezburger changed the URL of their RSS feed which the gadet uses to get its data.

v1.0.1 uses the new URL and normal service is resumed.

Had a bitch of a day today in work, with an application I was playing with refusing to play with Active Directory (largely because I’ve never used LDAP before and couldn’t figure out the weird bloody syntax).

So I’d really like to offer a quick thank you to Jarek Gawor for developing (and releasing) his LDAP Browser/Editor which let me double check that I was connecting to the right server/port and play with the settings enough that I eventually got it sussed. Great wee Java tool.

I need a quick bitch.

I love PHP. It’s everywhere. All my sites are written in it. My CMS is written in it. My blog engines, WordPress and b2evolution, are written in it. It’s free. It runs on any platform. Hosts all support it. With PHP 5 they’ve even done a lot of work on PHP4′s main downfall – lack of OOP support.

One thing really pisses me off though – it’s totally inconsistent.  Consider these two functions:

1. strstr — Find first occurrence of a string
2. in_array — Checks if a value exists in an array

Take a close look. See the signatures?

string strstr ( string $haystack , mixed $needle [, bool $before_needle ] )
bool in_array ( mixed $needle , array $haystack [, bool $strict ] )

In in_array the first parameter is what you’re looking for and the second is what you’re looking in (more or less consistent with preg_match).  In strstr (and its derivatives) this order is reversed. Who on Earth let that slip through? I’m yet to find a free text editor that will tell you which parameters a given function expects (Dreamweaver does a decent job but it’s bloody expensive for a text editor!) the way Visual Studio does for C#, which I use a lot in work.  Given that situation, you’d expect consistency in this sort of thing.  Apparently not so. Instead, every time I want to use one of these functions I have to do a quick Google to bring me to the PHP manual page to tell me which order the parameters come in.

Of course they can’t even fix that without breaking backwards compatibility either, so we’re probably stuck with it.  Bloody marvellous!

O hai!

I hart lolcatz.

I hart lolcatz so much dat wun dai I thoughted “I can has lolcatz wen I makes teh pooter turn on?” So I maded a Vista gadjit an now I has new lolcatz every dai.

If u hart lolcatz liek mee an wants lolcatz in ur pooter makin u laff, downlodes mah gadjit. I has tested it 4 liek rly long time. It rly works, srsly. An evry1 needses moar lolcatz.

Kthxbai.
