Wear24 NFC ROM from AOSP

THIS REPO IS STILL VERY VERY UNDER CONSTRUCTION

This project is a modified mirror of Google's AOSP specifically targetted at the Quanta dorado (sold as the Verizon Wear24) to pair with our custom NFC kernel. Our aim is to get the watch to support NFC, a feature Verizon promised, yet never shipped. In the future, greater modifications may be made to support more features or update to newer systems such as Oreo or "H".

Branches

PLEASE CHECK WHICH BRANCH YOU ARE ON BEFORE BUILDING!

This repository has a different branch for each Android Wear AOSP build: android-wear-7.1.1_r1, android-wear-8.1.0_r1 and one for system H when we add it. These branches are named identically to the applicable Android Open Source Project branches.

Our releases are automagically built by our Travis CI integration and uploaded to GitHub releases.

Cloning

Due to high file sizes, it is recommended to only clone the whole repository if necessary. If you do plan on doing so, it is highly recommended you use SSH and not HTTPS.

To do so...

1. Open the terminal
2. Paste the following code, substituting your GitHub email: ssh-keygen -t rsa -b 4096 -C "[email protected]"
3. When asked to choose the file location, press ENTER (accept the default location)
4. Enter a secure passphrase (which you'll remember!)
5. Start the ssh-agent (enter eval "$(ssh-agent -s)" into the console)
6. Add your SSH key to ssh-agent (type ssh-add ~/.ssh/id_rsa and enter your passphrase when asked)
7. Add the SSH key to your GitHub account
8. After, just clone the repo using git clone [email protected]:quantify-nfc/Wear24-NFC-ROM-AOSP
9. Follow the instructions under Repo Setup

Pushing

If you are planning on pushing large changes, it is recommended to change the following git config values:

git config core.bigFileThreshold 15m
git config --global http.postBuffer 157286400

Meanings

Config value	Description	Benefit
core.bigFileThreshold 15m	Disables delta compression on files larger than 15 MB	Vastly reduces git push time
http.postBuffer 157286400	Increases the Git buffer size to the largest file in the repo	Decreases failed push attempts

Repo Setup

Automatic

A repo setup script is included in the repository. Just run:

. repo-setup.sh

Manual

1. Install all required packages

sudo apt install git-core gnupg flex bison gperf build-essential zip curl zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 lib32ncurses5-dev x11proto-core-dev libx11-dev lib32z-dev libgl1-mesa-dev libxml2-utils xsltproc unzip

2. Install the Google Repo tool

mkdir ~/bin
PATH=~/bin:$PATH
curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
chmod a+x ~/bin/repo

3. Initialise a Repo client

# For 7.1.1
repo init --depth 1 -b android-wear-7.1.1_r1 [OR THE BRANCH YOU ARE USING] -u https://android.googlesource.com/platform/manifest

4. Synchronise the Android source

repo sync -c --no-clone-bundle -j$(nproc --all)

5. Check that the local manifest is located at .repo/local_manifests/local_manifest.xml. This contains our custom Repo 'submodules'. If this doesn't exist, then download it from GitHub.

Pulling updates

Just running git pull by itself isn't (normally) enough anymore! Follow a few simple steps every time a change is made:

1. Change to the top-level AOSP directory (e.g. cd ~/Wear-24-NFC-ROM-AOSP)
2. git pull
3. repo sync

Building

Automatic

After setting up the repo, just run . build.sh in the repo root.

Everything will (hopefully) build automatically.
