We’ve trained several thousand engineers on Embedded Android. Here’s a sample of what past attendees had to say about this class:

One of the best courses I have attended. We need more courses from Karim.

The instructor was highly knowledgeable about the subject matter and yet presented it in varying levels of difficulty to suit the needs of all participants. The subject was also highly relevant to my work domain and I learnt a lot of useful ideas and tricks from the course work. In particular, the hands­on exercises gave a better understanding and confidence over the subject. Karim is an excellent instructor and can share his knowledge in a very appealing and convincing way!

The course covered a great deal of material, there was a wide dichotomy of student knowledge, the instructor did a good job of keeping everone interested but not good too fast or too slow. The hands on exercises were good.

Great knowledge and worth every penny. Awesome class, just a fine hose of info. Would be nice to have a second class for other info. Great job!!

This is the best training I have attended in [company name removed] so far. I was completely new to the topic. We should definitely have more training from Karim in [company name removed].

Karim rocks. Knows his stuff.

The instructor was highly knowledgeable about the subject and answered all questions and clarifications with immense interest. The course along with hands­on exercises was very, very useful!

Great instructor

Mr. Karim Yaghmour has a wealth of knowledge regarding Android development and Linux. He presents material with zeal, care and consideration of the audience.

The class was a great look at Android under the covers. Karim’s knowledge of the entire stack and the exercises we did during the week helped me understand and learn effectively. ” — A.I.

Android from the root 🙂 ” — F.J.

As a HW guy with a smattering of embedded SW background, I think this class is a great inside view into the guts of the AOSP that I actually care about. ” — T.W.

Excellent class & worth every minute of class. The training explains the root mechanisms & of each layer & not just touch on subject but rather code walkthrough makes this class excellent tool for someone who intend to know all aspect of Android from App to kernel level.

The amount of things I learned in this class far exceeded my expectations. I couldn’t have been more satisfied. And at the price Karim charges this class is a bargain. ” — B.B.

A seriously technical class for any group who is about to undertake Android development, provided by a knowledgable software engineers. ” — R.

Adapted class curriculum to the student’s needs on the fly – nice job ” — D.L.

It is almost impossible to find material about porting Android to new hardware, short of Karim’s Embedded Android book and class. This is knowledge that companies releasing hardware just seem to keep to themselves. This class has made my task from seeming impossible to just hard. I can deal with hard, as long as it is possible. 🙂 ” — J.S.

Embedded Android Class, hands on the source from STX to ETX. At the end only one thing remains: “Use the Source Luke” ” — K.-A.P.

Karim’s engaging presentation style and knowledge of the Android Operating System (could he be the most knowledgeable person on the AOSP outside of Google?!) made this class extremely useful and informative both in technical information and practical, hands-on experience. I highly recommend this class to anyone who is interested in learning more about the Android OS or is looking to use/evaluate it for a project. ” — J.O.

This class is a great class to get your feet wet in embedded Android. ” — J.L.

Quickest way to understand the depth and width of Android stack. ” — M.

After the class, I feel like I have been doing Embedded Android for years. ” — S.S.

I have experience in embedded Linux and Android applications. This class charts a path between them. ” — M.S.

It’s really fun to listen to the to the trainer because you can feel the passion and see the knowledge he has.

Very technical, down to details course, definitely recommended!

Huge amount of knowledge presented, trainer can answer also questions way outside of the course subject. ” — J.O.M.

Learn the communication flow within Android and how things play together. ” — T.G.

Very interesting class with hands-on. Good overall view of Android’s architecture. ” — P.G.

I’m a high-level software engineer. I really like this course because it helped me understanding the whole cycle for apps from top to bottom all over Android systems. ” — I.Y.

Karim knows this stuff inside-out and is able to explain things quickly and allow the class to learn in a variety of ways ~ verbal, visual, hands-on.

The embedded Android training session by Opersys covered all the relevant parts of the Android framework as well as the Linux kernel that it runs on. The training provided was immediately beneficial to our internal embedded Android project.

I’m sure this class saved me countless hours of source hunting and fruitless searches on the web regarding topics that are under or non-documented.

Taught by an extremely knowledgable instructor, this course will give you everything you need to port Android to your device.

If you want to start developping under the hood of the Android OS, this course delivers what you need in a one-week hands-on training.

Great course to help you dig into Android and its concepts

A nice, well-documented overview of the internals of an amazing framework
Nevertheless, the system lacks some documentation, hence we need this
Deep-dive into the vast framework
Reverse, bottom-up approach
Of the Linux-based framework
In a quite fast-paced walkthrough
Definitely worth every second

Value for money!! 😉

Great class! It combined broad overviews followed by the kind of detail needed to understand what is going on under the covers.

Although Android is Linux, it is Linux with considerable kernel modifications, and a completely different system administration and toolset; so great are the differences that it feels unfamiliar to every experienced Linux developer.
Karim provides a well organized presentation of the crucial concepts, and enables students to gain a full appreciation of not only how the Android architecture works, but also why it works that way.
In 22 years of professional software development, this has easily been the most valuable training session I’ve attended.

One of the best embedded development classes I have participated in.

I learned both bredth and depth during the course, an impressive accomplishment. Exceeded my expectations.

Extremely helpful in both providing a general overview and understanding, as well as get into details most relevant to us.

I’ve been working on Android for 4 months and I think I learned more about the system in these five days than those foru months!

While this class won’t make you an instant expert in the Android AOSP, it is a great way to learn basic structure of the AOSP code-base, and get a solid grounding in the steps required to make new hardware functionality available to higher levels of the Android stack, up to and including the application level.

Android is so big that it is easy to get lost in it. I now have been given directions so that I can find my way no matter where I go in it.

This is a great class. Every serious embedded system engineer should take it!

I am now very well equipped to add Android support to my company’s SoCs.

Karim is the Wayne Gretzky of embedded Android. His embedded Android training far surpassed my expectations. It gave me a more solid understanding of Android in one week than I was able to learn on my own in several months. This directly translates to a huge boost in productivity and efficiency, which will help my team deliver our embedded Android solution on time. ” — B.A.

Karim can light fire by rubbing two ice cubes together.

Karim is one of the few instructors that has a deep understanding of the entire Android stack. I highly recommend this course for any engineers who work on embedded Android projects.

From beginners to practitioners

Must for all developers, designers and architects

An eye opener for newcomers

Even with a fair bit of Android experience, this class has undoubtedly given me the information I need to become a great Android developer.

Karim is very friendly and can teach all the secrets of embedded Android!

If you’ve ever wanted to poke around in Android’s guts, Karim’s class is a brilliant introduction to the architecture.

Excellent introduction into Android concepts.

Find how to get yrou way in Android.

If you’re a strict deadline and you need to become an Android platform guru as quickly as possible, then you need to take this class!

An amazing intro into the world of Embedded Android.

Nice bridge do go from embedded Linux to the robot.

This hands-on course benefits greatly for the beginner/advanced developers in diving into Android for embedded devices. ” — P.D.G.


Great way to explore the Android internals.

By the end of this class, you will have programmed a new device into the AOSP from the hardware layer to an app that calls it, including building a new SDK that exposes the h/w via calls available from the eclipse development environment.

Very good class. Hands-on examples clearly demonstrated ideas from lecture. Having slides available on line should make it easier to ‘spread the gospel.’ Thanks for an enjoyable class where I learned more than I thought I would. I look forward to seeing where headless Android takes you.

Excellent, detailed look into AOSP with great hands-on training!

Best class I’ve attended in years. Karim’s deep knowledge of the Android ecosystem is impressive.

Right from app to driver … All things are explained nicely — if not then at least references are provided. ” — P.

The embedded Android class has saved us months of effort by giving us a great head start on our development.

Android should be taught by a person who is 1) Linux expert, 2) Hands-on Android expert, 3) has deep Linux coding experience. I think Karim is a mix of all 3 points which makes his class very interesting. One can learn more than just Android Development!!

This is a great class for both beginners and experienced Android developers. It provides insight into a broad array of features in Android platform. I will definitely recommend this class to others!

I found this class very informative. I now have a better understanding of all the layers in Android from the kernel all the way up to the App layer.

This class provides a great bootstrap into the Android modules stack.

If you want to know how all the layers fit together and work, take this class.

Fun, informative on the internals of Android, boot-strapping from the Android device manufacturer perspective. Highly recommend. ” — B.X.

Great hands-on class.

Really liked the depth & and the amount of specific knowledge this instructor has! ” — E.S.

I truly appreciate the hands-on approach of each step building upon the previous.
