LineageOS 17.1 for Sony Xperia devices lilac/xz1c, pioneer/xa2, xz2c, and perhaps more to come.

How to build LineageOS

Initial setup

Follow the steps for pioneer or really any other device until you get to Initialize the LineageOS source repository:

https://wiki.lineageos.org/devices/pioneer/build/

Make a workspace:

mkdir -p ~/android/lineage
cd ~/android/lineage

Initialize the repo:

repo init -u https://github.com/LineageOS/android.git -b lineage-17.1 --git-lfs

Create local manifests, e.g. by checking out a copy of this project and moving the files to the LineageOS folder:
```
git clone https://github.com/Eclipse-Community/build_lineage.git
mv build_lineage/local_manifests/ .repo/
```
If you want to save some space, you can remove files for devices you're not interested in building. Open .repo/local_manifests/roomservice.xml and remove the repos from the manifest. They're all in groups of three, kernel, common, and device. Remove the three or six that don't match what you're building.
Sync the repo:
```
repo sync
```

Tell git about Change-Id trailers

git config --global --get-regexp 'trailer\.' | grep -qF 'Change-Id' || git config --global trailer.changeid.key "Change-Id"

Build procedure

For XZ1 Compact (lilac) Only

Copy dumped firmware blobs into place for the build

(Semi-)optionally apply patches

Compiling without patches is untested. It will probably work if you want a more stock build. However you will need to comment out 'TARGET_KERNEL_CLANG_VERSION := r416183b1' in /device/sony/$platform-common/BoardConfigCommon.mk or BoardConfigPlatform.mk if you go without --minclang.

To apply all patches (recommended):
```
build_lineage/patches/applyPatches.sh
```
To apply only the minimal (required & security fix) patches:
```
build_lineage/patches/applyPatches.sh --minimal
```
To apply only the minimal & new Clang patches:
```
build_lineage/patches/applyPatches.sh --minclang
```
Setup the environment

$device is the device you want to build with. For now lilac, pioneer, and xz2c.
```
source build/envsetup.sh
lunch lineage_$device-userdebug
```
You may also want to use 'lunch lineage_$device-user' instead if you use certain banking apps and such.
(Optional) Build with MicroG apps

!!Requires all patches!! or the signature spoofing patch
```
export WITH_GMS=true
```
Build LineageOS
```
m bacon
```

When completed, the built files will be in the out/target/product/$device directory.
