BilbaoBus Summer Edition

Over the last few months I’ve been sleeping quite less than recommended, and this is the reason…


We’ve revamped most of the app to make it cuter, neater and more usable. So, next time you need to catch a bus in Bilbao, don’t hesitate and download BilbaoBus.

Riptide GP: An Android Game Postmortem

The website Gamasutra frequently publishes articles where game creators talk about the development process of a game. These papers are called Postmortem because they are written once the game’s been finished/released and that’s precisely what it makes them so so valuable. They are no just about “how brilliant we are”, on the contrary, Postmortems usually focus on mistakes and lessons learned.

Although most of them may be considered a must-read, I’ve found particularly interesting the one about Riptide GP where the guys of Vector Unit describe the process of porting a 360 xBox game (Hydro Thunder Hurricane) to the Tegra 2 platform. Hot topics such as funding, monetization and piracy are also addressed in the write-up . Definitely a good read!

Android: Finding Memory Leaks

Recently while I was working on the next version of Archer Master, I’ve had to roll up my sleeves and find a memory leak. By and large, a memory leak in one’s application is frequently a synonym for having painful time, no matter which language you’re coding in. I have experience in finding leaks in the non-managed languages such as C/C++ but this was my very first time with a managed language (Java). In my case, the leak was caused by a lost strong-reference to a LinearLayout used to hold advertising, so each time a level was played, the entire activity remained in memory and wasn’t collected. As a result, after playing several levels (the number depended upon the particular device), a OOM exception raised and the game crashed.

It’d have been virtually impossible to find the leak without a tool like MAT. Moreover, a good understanding of the different types of references (strong, weak, soft…) and the concept of Dominator Tree  also help.

When I’ve got a little more time I’ll write about the whole process I went thru (if anyone is really interested please let me know)… but meanwhile, this is an invaluable resource if you find yourself in a similar situation and don’t know how to start:

Good luck with your leaks! 😉

Quoders and Archer Master

It’s been a long time since my last post and this time there’s a good reason for it 😉 I’ve been working hard to release the first version of Archer Master, an archery game for Android. Archer Master is free, so give it a try!

Moreover, I’ve co-founded a new development studio named Quoders.

Hopefully, this is the beginning of something great…

My New Nexus

It’s been six weeks waiting for the Nexus One and finally it’s here.  The N1 runs smoothly and fast a Cyanogen ROM. Even though I’m using the same 3G connection (vodafone ES), now browsing the web is a delightful experience compared with HTC Magic. The battery lasts almost a couple of days with a normal use (email, web, rss, etc).

The parcel didn’t include any sort of manual except a couple of sheets with tips and tricks.

Here you can see more pictures.
