How To Build

Step 1: Setting up the Build Environment.

This "How to" is scoped for new builders with moderate PC skills.

You'll need Linux to be able to build AOSPA. You have three choices here; you can:

1. Install Linux natively on your computer.
2. Dual boot Linux and Windows.
3. Use virtual machine software ( virtual box, vmware ) to run linux.

NOTE: I recommend you use Ubuntu 15.04 to build. That's what I use.

Now read this: http://source.android.com/source/initializing.html

Step 2: Downloading the Source

NOTE: Some say that it is better to download the ROM source and put in your local manifest later. I don't know if that's best but that's what we are going to do.

BEFORE YOU BEGIN: You are about to start downloading 15 - 20 Gigs of data. That could take a very long time, so plan accordingly. I like to start just before I go to sleep and let it go overnight! If you have to work, perhaps start it before work and let it go through out the day.

Execute the following commands in a linux terminal:

mkdir ~/Desktop/AOSPA-N
cd ~/Desktop/AOSPA-N
repo init -u https://github.com/AOSPA/manifest -b nougat-mr2
repo sync -j4

WARNING: There may be times, towards the end when it seem like, the download is stuck and not making any progress because there are no updates on the screen. BE PATIENT!, open a program that will show how much bandwidth you are using to be sure!

Step 3: Create device entry

AOSPA does automatically download the needed repos, but we need to add the device entry first.

Execute the following commands in a linux terminal:

cd ~/Desktop/AOSPA-N/
bash <(curl -s https://gist.githubusercontent.com/dady8889/07d8bdcffceb0538b4774fe5ca37c9ab/raw)

Notice the output of this command, if you see only OK, we can continue.

Step 4: Building

Turn off Ninja (optional)
Ninja is supposed to help make incremental updates more efficient but you aren't doing an incremental update; are you?

export USE_NINJA=false

Make sure there is enough memory for Jack (required). Without this you can get out-of-memory errors.

export ANDROID_JACK_VM_ARGS="-Xmx4g -Dfile.encoding=UTF-8 -XX:+TieredCompilation"

NOTE: Build times depend on your PC performance specifications. It may take anywhere from 1 hours to 15 hours depending on system specs for a complete build.

We are going to build. If you want to use autopatch, execute following commands:

cd ~/Desktop/AOSPA-N
export AUTOPATCH=true && ./rom-build hi6250 -s

If you want to apply patches manually:

# If you tried autopatcher before, execute command below
unset AUTOPATCH
# If not, continue
cd ~/Desktop/AOSPA-N
./rom-build hi6250 -s
# After syncing (after you see 'Starting compilation') press CTRL+C (few times, maybe)
cd ~/Desktop/AOSPA-N/device/huawei/hi6250/patches
./patchtool -p
cd ~/Desktop/AOSPA-N
./rom-build hi6250

Wait™ ...

Step 5: Troubleshooting

In case it won't download the needed repos in ./rom-build, you need to download them manually.

cd ~/Desktop/AOSPA-N
repo sync vendor/huawei/hi6250
repo sync device/huawei/hi6250
repo sync kernel/huawei/hi6250

Step 6: Submitting patches

If you would like to submit patch, do the necessary changes to specific repo and make patch with the bundled git-makepatch tool, or use git commands (not part of this readme). Necessary information about the tool is in its help command. You can do

~/Desktop/AOSPA-N/device/huawei/hi6250/patches/git-makepatch <patch-name>

while you are in target repository. You can add ~/Desktop/AOSPA-N/device/huawei/hi6250/patches to your PATH to shorten the command. Then you can copy the patch from your desktop and test it in the device tree. You can send the patch by making an "Issue".
