Android ROM cooking: A practical Tutorial (DroidCon Torino 2014)Ron Munitz
My workshop at DroidCon, February 2014, Torino, Italy.
In this tutorial, you will have a hands-on journey of customizing and building Android right off the Android Open Source Project (AOSP). We will begin with introducing the concepts of ROM cooking for any Android compatible device, and we we will then walk-through the build system of the AOSP. You will learn what Android is made of, how to build a bullet speed Android emulator, and how to build a minimal, fully operational Android configuration that will run on the QEMU virtual machine. You will step out of the classroom with the ability to follow the exact steps made in the tutorial to jump-start building your own Android system for any Virtual Machine - and with the tools and knowledge to build it for any custom device! Note: The tutorial is extremely hands on. Although it is not a strict requirement, it is strongly recommended to come prepared with a setup of Linux or OS X with the source code for an Android platform from http://source.android.com

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Harmony open source implementation.
27. Android Open Source Project
(AOSP)
Almost... fully open:
■ Google publishes source code when they
decide it.
■ No real interaction with Google teams.
■ Not everything is open source:
○ Proprietary binary drivers
○ Google Apps: Google Maps, Gmail, Google
Contacts/Calendar/Bookmarks Sync, Google Talk,
Play Store (Android Market), Youtube, Weather
widget, Text-To-Speech, Voice Search.

○ Tablets
○ Google TVs
■ Support multiple Android versions.
45. Diversity - Android versions
Use features of newer Android versions
while staying compatible with older runtimes:
Isolate special functionality in separate classes.
MyInterface implementation;
if (Build.VERSION.SDK_INT >=
Build.VERSION_CODES.FROYO)
implementation = new FroYoImplementation();
else
implementation = new CompatibleImplementation();
47. The upgrade problem
■ Updating the custom user interface to a new
Android version requires a lot of work.
■ Manufacturers focus on selling you their
latest hardware, not providing support for
older hardware.
■ On Android, upgrades usually depend on
carriers. (The Proximus case)
■ Many manufacturers don't do OTA updates.
■ Average official support time:
○ 3 years for Apple
○ <= 2 years for most Android phones.
48. The upgrade solution:
Installing community ROMs
Why hack ?
■ Give choice to the user.
■ Remove bloatware.
■ Provide longer term support and upgrades.
Custom ROMs:
Complete firmware (OS, UI, base applications)
created by the community.
49. Hacking - Custom ROMs
Different kinds of custom ROMs:
■ Modified original vendor versions
■ Ported from another device (experimental)
■ Build from source (AOSP)
Hack challenges
■ Locked hardware (HTC S-ON).
■ Binary drivers:
Radio (Wifi - Bluetooth - GPS), Graphics,
NFC, sometimes accelerometers.
58. Hacking basics - 2. Root access
■ Root access allows to perform restricted
operations like:
○ writing files on system partition
○ flashing a custom recovery directly from Android
OS.
■ It requires:
○ Patching or replacing the kernel
○ - or -
○ Use phone-specific kernel exploits
(mainly through ADB).
60. Recap: How to change your ROM
1. Go to a forum / wiki and learn the procedure
2. Use:
a. fastboot
b. the vendor flash tool
c. a root hack
to install a custom recovery on your phone.
3. Download a custom ROM as zip file and
place it to your SD card/internal storage.
4. Reboot your phone in custom recovery and
install the ROM. Reboot. Done.
