INTRODUCTION

AN OPEN-SOURCE AFTERMARKET-DISTRIBUTION OF ANDROID

A PLATFORM WITH SUPPORT FOR ALMOST 80 DEVICES!

PROVIDES THE LATEST AND GREATEST VERSION

SETS UP A GREAT PLATFORM FOR DEVELOPERS AND ENTHUSIASTS

SHARES THE “MADE BY DEVELOPERS, FOR DEVELOPERS” MINDSET, JUST LIKE DROIDCON


BUT IS IT?


YES


YES


YES(IF YOU OWN A NEXUS DEVICE)

WHAT ABOUT THE OTHERS?


CYANOGENMOD: WHY?CHANCES ARE, YOU CANNOT BUILD ANDROID FOR YOUR DEVICE

IT ONLY BUILDS ON NEXUS DEVICES

MOST PEOPLE ARE STILL STUCK IN 2.1/2.2

SOME PEOPLE JUST ENJOY BEING IN CONTROL OF THEIR DEVICE

OTHERS ENJOY THE EXTRA FEATURES

MULTIPLE DEVICES, THE SAME EXPERIENCE


CYANOGENMOD: THE INTRINSICS

A SINGLE DEVELOPMENT TREE TO RULE THEM ALL

OMAP

TEGRA

QUALCOM MSM

...

TRADITIONALLY, VENDORS TEND TO KEEP ONE TREE FOR EACH DEVICE

LEADS TO CODE DUPLICATION, HARDER UPGRADE PATHS


MAIN DIFFICULTIES

DEALING WITH CLOSED-SOURCE DEVICES

ONLY OEMS HAVE ACCESS TO SOURCE AND DOCUMENTATION

PORTING THE HARDWARE PARTS IS HARD

WE BASE OURS IN REFERENCE IMPLEMENTATIONS BY QUALCOMM, TI, ETC

SOMETIMES A LOT OF REVERSE ENGINEERING IS NEEDED
