Tutorial: Creating a Cordova/Phonegap plugin for Android
Sep 28th 2014
Cordova is certainly one of the most promising and state of the art framework to develop cross-platform HTML5-based mobile apps. I’m a big fan of this framework, but unfortunately some stuff are in my opinion hard to understand for beginners when it comes to customize or extend an HTML5-based app implement their own special function calls. Special functions? Just think: what if your App should launch a videoplayer when the user clicks somewhere in your app? Or what about integrating a customized alert box (aka Toast) or overlaying a Open GL View for a 3D visualization? Those are things you won’t be able to realize without using a Cordova plugin. More >

Here’s quick tip I wanted to share because you might face this little issue: you have eventually recorded some voice notes with the Samsung Android application and wanted to share these it with your friends or integrate it into an email and then… you found out that all your notes were recorded as .3ga files that you couldn’t even playback with your favorite media player. Ouch…

Android min3d quick tip: Changing textures of 3DS and OBJ 3D models at runtime
Dec 22nd 2012
In the previous tutorials about min3D for Android we took a closer look on how to optimize the work flow from Blender or Daz3D to min3D. In today’s article you will learn how to easily change the texture of a 3D object stored in *.obj or *.3ds format. Although this sounds very easy while writing this tutorial, I’ve noticed numerous problems by loading these 3D objects within min3D especially if you are modeling with Blender. This tutorial should be considered as More >
Unity 3D WebCamTexture rotation problem with Android – How to rotate the camera picture ?
Aug 21st 2012
I read that a lot of people are having problems with the Unity WebCamTexture and Android. Indeed the problem comes from the fact that the texture streamed from the webcam is always flipped by 180 degrees and you will always get a wrong rotated picture of the camera (even if you turn your device (see picture)). This is really annoying as you would expect that the WebcamTexture will show you a correctly orientated picture of the camera. Obviously the API of WebCamTexture doesn’t More >
Unity GPS plugin development tutorial: building a Android plugin for Unity with Eclipse and Ant
Apr 28th 2012
[This entry was updated in Feb 11, 2015 ] [Initial post date: Apr 28, 2012] This tutorial is about creating and compiling your own Unity GPS Plugin for Android. I wrote this tutorial in order to help those who are getting angry and fed up with missing information about the process of writing their own Unity Android plugin.
My motivation was to get real speed values out of the GPS of my device, because the inbuilt Unity Input.location functions returned only latitude and longitude values that where (now that we’ve solved the problem I can assume that ) only computed on network basis and not on the data provided by the inbuilt GPS receiver (http://forum.unity3d.com/threads/132587-GPS-Input.Location-accuracy-question). This was pretty annoying so I decided to write my own GPS Plugin for Android.

How to export from Blender to Unity 3D with textures tutorial
Jan 3rd 2012
Believe me or not Unity 3D will be the next hype in the indie game industry and once you have discovered this tool and exported your 3D scenes to your iPhone, Android or even Flash (thanks to the new Molehill support) you will understand why. But that’s not the point of our discussion 😉 There is a topic that comes very often in forums concerning the export/import of textures in Unity 3D: how to export 3D objects or geometry made with Blender (up to 2.5) in Unity with textures? Yes with textures… The problem is that the workflow is not very clear and often textures are missing what is pretty annoying because once imported in Unity 3D you will need to assign them manually over the Material options… it’s a real pain but fortunately there is a nice solution… More >
How to resize the Flash Player from Flash with fscommand and C#
Sep 25th 2011
How do you resize the Flash Player or to be more precise the width of window showing your animation? Whereas with AIR this is done with few lines, the Flash Player will not allow you to resize its window. The first idea when trying to solve this issue was to write something like : stage.width = 1024; . Yes, this could work but this value can’t be overwritten and the Flash Player won’t be resized. But how to realize this, let’s say if you have several screen resolution to target and want to automatically resize the Flash Player? Here is my solution
Convert FLV to MP3 with FFMpeg
Sep 5th 2011
This is perhaps one of the most frequently asked questions on the web: you’ve downloaded a nice FLV (let me guess, from YouTube 😉 ) and you want to convert it into a MP3 to be able to play it on your iPhone or mobile phone. How to realize this? Yes, there are tons of FLV to MP3 converters and media converters on the web. But seriously, why do we need something so sophisticated whereas a simple command line will do the whole work for us? More >
