Android OTA Updates - Andrew Boie, Intel
AOSP is distributed with the source code and tools for full (whole image) and incremental (binary patch) secure over-the-air (OTA) software updates, specifically an alternate boot target Recovery Console, the updater logic itself, and tools to create software updates. There is no publicly available documentation for how this mechanism is supposed to be integrated. This presentation will give a detailed end-to-end description of how software updates are created, digitally signed, and applied to the device. There will be a discussion on the plug-in architecture and Edify language which allows builders to customize the OTA updates with platform-specific features. This is an updated version of a talk presented at ABS in 2012, with details on new OTA features including block-level OTA updates in Lollipop.

Generalizing Android for Low-Cost 64-Bit ARM-Based Community Boards - Khasim Syed Mohammed, Linaro
Linaro is developing an open hardware platform specification to encourage software development on low-cost boards to lower the cost and accelerate the availability of maker and embedded products based on ARM SoCs. By end of 2015 there will be many compliant boards based on and adhering to this specification. The key challenge for the Android community is to enable and maintain Android for multiple platforms on a common code base. This presentation highlights the issues like non-standard SOC customizations, peripheral controller customizations from vendors and shares the possible solutions through Android software generalization.

Build and Distributing SDK Add-Ons - Dave Smith, NewCircle
Building powerful device-specific features into your Android device is only half the battle. For application developers to easily take advantage of those features, they need to have them exposed through a custom SDK distribution. Google provides all the tools to do this within AOSP via the SDK add-on target. This target provides all the tools necessary to generate packages that you can distribute to Android application developers using the SDK Manager tools they are already familiar with to build and test their code.

In this session we will discuss some short background about how AOSP device targets are structure. Then you will learn how to take an existing AOSP device target, apply an SDK add-on build target, and techniques for distributing the result to application developers.

Fuzzing the Media Framework in Android - Alexandru Blanda, Intel
This presentation focuses on exposing a software testing tool developed with the purpose of fuzzing the media framework in the Android OS. Approaching this topic is of particular importance given the fact that currently there is little prior work done, that concerns the issue of fuzzing media content in the context of the Android OS. The main idea behind developing this fuzzing tool is to create corrupt but structurally valid media files, direct them to the appropriate components in Android to be decoded and monitor the system for potential security vulnerabilities. The main parts of the talk include: an introduction to fuzzing and the reasons that make media content an attractive target, an insight on the implementation of the tool and the testing campaign and a series of results obtained using this approach, including a number of CVE entries that were discovered during this process.

Chaining HALs - Hunyue Yau, HY Research
HALs on Android are shared libraries with well defined names for entry points. Like all shared libraries, they can be chained. Chaining HALs can allow reuse or debugging of existing binary only HALs. Many Android systems are based customization of reference designs or even repurposing existing off the shelf designs. Chaining HALs provide addition customization options to existing Android systems. Chaining HALs can provide an alteranative vendor delays and hesitation with customizing or fixing binary only HALs.. Customization on a HAL level can have added benefits such as keeping existing security models intact futher up the Android stack.

In this session we will look at how the chaining can be done along with the pitfalls with chaining a HAL. A simple chained implementation will be discussed to illustrate this.

Utilizing the Android Open Source Project to Support Controllers for Single-Use Devices. (X-Ray Guns! Pew Pew!) - Ben Friedberg, SDG Systems
When is a Nexus 5 phone more than a multi-use communication device? When it's controlling an X-Ray gun! SDG Systems was approached by Tribogenics Inc to retrofit Google's Nexus 5 phone to act as a controller for their prototype X-Ray Florescence Processing (XRFP) gun. SDG was to pare AOSP 4.4 down to a single application and then to act as the brains of the gun, communicating with the various elements and controller boards to create a cohesive and user-friendly unit.

Throughout the project SDG came up against a series of interesting problems which Ben will lay out along with the solutions that they came up with. Some of these issues include: Pre-5.1 'kiosk' mode, simultaneous USB Host mode and charging, external video, reusing Android settings, retrofitting the status bar and statically linking against NDK libraries within Android Studio. Attendees will likely not be irradiated.

Memory Management Internals - Karim Yaghmour, Opersys
The Android stack is fairly deep, with several key components impacting applications: the framework API, the system services, the virtual machine (be it Dalvik or ART), the native layer and the Linux kernel. Each of these components has an impact on the system's memory usage. Beside rules of thumb, there isn't much in terms of documentation on how the Android's internals manage and deal with memory.

This presentation will examine the Android OS' memory management, from the Linux kernel all the way up to the app layer. We'll discuss the features and limitations of every key component, how platform developers can navigate around those limitations and what to watch out for, and present the tools and methods available to understand each components' memory usage.

Android Verified Boot - Andrew Boie, Intel
Android Lollipop introduces new features for boot security, with a specification for build-time signing and run-time verification of the boot, recovery, and system images, with the bootloader controlling verification of the boot/recovery images and Linux dm-verity enforcing the integrity of the system image. There are also facilities for enrolling user-supplied keys via Fastboot so that custom images may be verified. In this presentation Andrew will detail how these components work together, the requirements for creating a compatible bootloader, how to use the available tools in AOSP to create signed images and keystores, and some discussion on the implications of these features with respect to OTA updates, covering the new block-level incremental update feature.

Platform-Level UI Customization - Karim Yaghmour, Opersys
In addition to being popular as a mobile OS, Android has increasingly been popular in the embedded world. Yet there's little to no information on how to customize one of Android's foremost features: its user interface. How can developers change the look and feel of the Status Bar or the Launcher (home screen)? How can they theme the OS? How can they create kiosk systems based on Android?

This presentation will walk embedded developers through how Android's user interface can be customized. We'll take each part of the user interface one by one, show how it's implemented, and demonstrate modifications to it. Examples will include the Status Bar, the Launcher, screen overlays, theming of the interface, theming the boot process, kiosk applications, etc.

Android Customization: From the Kernel to the Apps - Cédric Cabessa, Genymobile
On Linux, you probably know how to expand your OS with new drivers, new packages, new SDKs, etc and develop an app that uses all those features.
With Android, the “all in one package” approach makes it easy for beginner to start writing apps, but harder to add new features to the OS
In this presentation, we explore the best ways to customize an Android system to let your applications benefit from a change in the low level stack.
We will visit every layers of the Android system (kernel, hal, jni, services, aidl, ...) and see how we can integrate our work into Android’s APIs in order to make it available to application developers.

Building a General Purpose Android Workstation - Ron Munitz
In this tutorial, you will have a hands-on journey of customizing, building, and using a General Purpose Desktop variant of the Android-X86 project (Android-X86.org). The tutorial assumes previous experience with building Android off the AOSP, Android-IA, CyanogenMod, or any other build system, and describes the special additions of Android-X86, such as a Kernel build system, general X86 hardware detection based HAL's/firmware and live cd/disk installer generation and more. Then, we will explore the Linux friendly busybox minimal image, and describe the way a fully fledged Android version can be spawned out of it (with similar techniques for any other Linux distribution with the Android patches!) using chroot, and provide a listing of the ultimate Android init process.
We will continue the discussion with day to day uses, and a joint brainstorming of Linux developer uses, and justify Android-X86 as yet another X-less Linux distribution - until the time we add X to it...
As a special bonus, we will address how to make any app run using a user-QEMU based ARM translator (although we sure hope non "APP_ABI:=all" are quickly fading away from this world!)

Creating Platform Development Tools - François-Denis Gonthier, Opersys
Android platform development is challenging, even for the initiated. Part of this is due to inherent system complexity but part of it is also due to lack of documentation and appropriate platform-level development tools. Indeed, while Google does a good job a polishing app-developer tools, its platform tools are mostly undocumented and very uneven.

This talk will explain the work we've done on creating open source platform development tools for Android. We'll describe, for instance, how the popular Node.js framework can be used to create web-based platform tools such as the open source Opersys Process Explorer. We'll also describe how to create Java-based command line tools and package them as APKs by showing how the open source Opersys Reverse AIDL tool works.

Android Based Penetration Testing Framework - Ron Munitz
"Pentest" (Penetration Testing) is the somewhat Sisyphean art of finding the weakest link in the chain of end to end products such as Clients (Web, Mobile, others), DB, Servers, and a bunch of other software and hardware components. It only takes a single weakness to take down an entire project, and it's better be done in-house, then by some hostile adversary.

As the mobile apps have become the dominant way to consume data for many services, their nature, given the fully available "client" side via the different App stores can serve to simulate real load scenarios, with arbitrary client side scaling. In this presentation we will present an Android based Pentest framework that not only exhausts the server exposed control/REST APIs , but also the behavioral and data path in a fast, reliable, easy and scalable way, using customized distributed Android instances.

As opposed to solutions aiming to test the client side, this framework aims to test a real system under real loads.The audience is anyone interested in a general Purpose Android Operating System, in Linux, in ROM cooking, Android Build Systems and the likes.

Doing big.LITTLE right: little and Big Obstacles - Vitaly Wool & Vlad Rezki, Softprise Consulting OU
The ARM's big.LITTLE technology implements a smart idea of combining high-performance cores are with low power ones to deliver peak-performance capacity at a lower average power cost. However, as big.LITTLE effectively is an asymmetrical MP, mainline SMP-oriented kernel "fair" scheduler can't take advantage of it. This talk will show what should be changed in the mainline scheduler to fit big.LITTLE architecture.

Multiple attempts were carried out to come up with the improvements implementing these changes, with the most notable coming from Codeaurora and Linaro/ARM. This talk will explain these implementations specifying their differences and similarities, and provide power and performance comparisons for both.
