If you have developed an Android app with video streaming, I’m sure you notice that Android use a pre-load of video buffer that fills in 10 seconds. This delay is hardcode in the source code. It’s very hard create a real time app to show video with this delay. There are several solutions out of [...]

As you know, it’s possible download the Android SDK for 32 and 64 bits architecture.  If you choose 64bit architecture you notice that some binaries are compiled to 32bit architecture 1 2 3 vega:$/android/sdk/platform-tools$ file aapt aapt: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.8, not [...]

I need to record some screencast with audio for my online classes of Android. It’s a good way to explain all the topics about programming and android development. Slides, exercises, moodle and screencast is a cool combination to create high-quality online courses. Also I use a digital tablet to write in the desktop/slides to clarify [...]

ESTUFA is a framework that provides several ways to connect and re-use mobile applications (in previous post I already presented this idea). The system allow build “execution chains” to connect and plumb two applications. This project is based in the idea of re-use and compose new applications using components (in this case Alchemist). It has a [...]

The last Google I/O a new feature based in Android and Arduino was released. The ADK allows the communication between Android and Arduino using a USB connection. Google have developed a library called “USB Accessory” in Android and Arduino. So, this library help us to send and receive data through USB interface. Using the USB accessory we can [...]

During the next months I will work in three interesting topics. The first of them is the creation of a new architecture based in Android that allow communicate and integrate applications. The second  is the port of ARviewer to iPhone platform using phoneGap. And the last one is the very well-know Arduino and its possibilities with Android USB Host. [...]

Security and Surveillance Systems have always been demand in the industrial and home environment. The cameras, which human eyes are able to collect all visual information from the environment. Extensions necessary and highly desirable in these systems, and that few possess, are integration and interconnection with other systems, video surveillance and display all the information on a mobile device, which lately is becoming [...]

Two weeks ago, I have received the new fashion gadget of Microsoft: the kinect sensor. Thanks for the community (libfreenect), this sensor designed for Xbox can be used in GNU/Linux systems. Lately I have the need of integrate anything with Android mobile (is it because I have over 3 years programming with Android?) So, I couldn’t pass up this opportunity! Using [...]

Since 6 months ago we have evaluated the possibility to implement a new AR interface (based in our project ARviewer) using phoneGap. phoneGap is a mobile framework based in HTML5/JS that allow execute the same source code HTML5 in differents mobile platforms (iphone, android, blackberry). It seem a good way to create portable source code. [...]

Today, the day has begun early. I woke up at 5.00 a.m. because we had the AVE at 6.35 a.m. The target of the trip is to attend the “Libre Software World Conferente 2010 – Málaga”. Three weeks ago, the Junta of Andalucía announced the cancellation the OSWC2010. In this moment, enterprises and associations as [...]
