  cd ~ && sudo rm -Rf ~/'android/lineage-15.0/'* ~/'.ccache' ~/'.jack-server' ~/'.jack-settings' && sync

===== Install git-repo =====

  * https://code.google.com/archive/p/git-repo

  mkdir -p ~/'bin' && wget -O ~/'bin/repo' 'https://storage.googleapis.com/git-repo-downloads/repo' && chmod +x ~/'bin/repo'

  ui = auto

===== Initialize Repo =====

****

  mkdir -p ~/'android/lineage-15.0' && cd ~/'android/lineage-15.0' && repo init --manifest-url='https://github.com/LineageOS/android.git' --manifest-branch='lineage-15.0' --depth=1 && sync

===== Motorola Manifest =====

  * If pulling in fresh sources, do not add this until the sources are backed-up ((that way the backup can be a clean-slate and be used for other non-Moto devices))

==== cm-14.1 ====

  mkdir -p ~/'android/lineage-15.0/.repo/local_manifests' && nano ~/'android/lineage-15.0/.repo/local_manifests/motorola.xml'

<code>
<?xml version="1.0" encoding="UTF-8"?>
<manifest>

  <!-- Motorola -->
  <project path="vendor/motorola" name="TheMuppets/proprietary_vendor_motorola" remote="github" revision="cm-14.1" />

</manifest></code>

==== lineage-15.0 ====

  * As of 2017/10/29, this is behind the ''cm-14.1'' branch for some reason ((refer to [[https://github.com/TheMuppets/proprietary_vendor_motorola/branches | branches]]))

  mkdir -p ~/'android/lineage/.repo/local_manifests' && nano ~/'android/lineage/.repo/local_manifests/motorola.xml'

<code>
<?xml version="1.0" encoding="UTF-8"?>
<manifest>

  <!-- Motorola -->
  <project path="vendor/motorola" name="TheMuppets/proprietary_vendor_motorola" remote="github" revision="lineage-15.0" />

</manifest></code>

===== Sources Management =====

==== Pull-in and Update Sources ====

=== Network Sync ===

  * As of 2017/10/29, this downloads 11.3GB for ''lineage-15.0''
  * If pulling fresh sources, this command is good to leave running overnight, and then followed up with a [[#backup_sources | backup]]

  cd ~/'android/lineage-15.0' && repo sync --current-branch --network-only --jobs='4' --force-broken --force-sync && sync

=== Complete Sync ===

  * Performs both Network and Local file sync

  cd ~/'android/lineage-15.0' && repo sync --current-branch --network-only --jobs='4' --force-broken --force-sync && sync && repo sync --current-branch --local-only --jobs='16' && sync

==== Backup Sources ====

****

  cd ~/'android/lineage-15.0' && tar -cvzf ~/'Downloads/lineageos-lineage-15.0-'$(date +%Y-%m-%d)'.tar.gz' '.repo' && cd ~ && sync

==== Restore Sources ====

****

  mkdir -p ~/'android/lineage-15.0' && cd ~/'android/lineage-15.0' && tar -xvzf ~/'Downloads/lineageos-lineage-15.0-'*'.tar.gz' '.repo' && sync

====== Modifications ======

===== Allow Signature Spoofing =====

  * This allows **microG Services Core** and **FakeStore** to fake GApps properly

  * https://github.com/FreeMobileOS/android_packages_apps_GmsCore/blob/20c65a1fc33ee28ae0d12a927bd243d4ee2e3abc/patches/android_frameworks_base-O.patch
  * Keep eyes on https://github.com/microg/android_packages_apps_GmsCore/pull/418 for when this is officially merged

  wget -O ~/'Downloads/GmsCore-android_frameworks_base-O.patch' 'https://raw.githubusercontent.com/FreeMobileOS/android_packages_apps_GmsCore/20c65a1fc33ee28ae0d12a927bd243d4ee2e3abc/patches/android_frameworks_base-O.patch' && cd ~/'android/lineage-15.0' && patch --no-backup-if-mismatch --strip='1' --directory='frameworks/base' < ~/'Downloads/GmsCore-android_frameworks_base-O.patch' && rm -f ~/'Downloads/GmsCore-android_frameworks_base-O.patch' && sync

===== Allow Location Providers Outside /system =====

  * https://github.com/microg/android_packages_apps_UnifiedNlp/blob/master/patches/android_frameworks_base-N.patch

  * This allows ** microG Services Core** to provide **UnifiedNlp** without having to be installed to ''/system/priv-app'' or having to have an outdated ''NetworkLocation.apk'' there

  wget -O ~/'Downloads/UnifiedNlp-android_frameworks_base-N.patch' 'https://raw.githubusercontent.com/microg/android_packages_apps_UnifiedNlp/master/patches/android_frameworks_base-N.patch' && cd ~/'android/lineage-15.0' && patch --no-backup-if-mismatch --strip='1' --directory='frameworks/base' < ~/'Downloads/UnifiedNlp-android_frameworks_base-N.patch' && rm -f ~/'Downloads/UnifiedNlp-android_frameworks_base-N.patch' && sync

===== Remove Deprecated HWUI GCC Flag =====

  * https://github.com/ValidusOs/frameworks_base/commit/f6e00f8ffba193ebe4b67da8a00b9122ff55ed73

  * Removes the deprecated ''-mapcs'' flag and prevents clang++ from reporting an error about it later on
  * Only has effect and needed if ''HWUI_COMPILE_FOR_PERF'' is ''true''

  sed -i 's/-marm -mapcs/-marm/g' ~/'android/lineage-15.0/frameworks/base/libs/hwui/Android.mk'

===== Avoid GNSS denials =====

  * https://github.com/elektroschmock/android_device_moto_shamu/commit/df314065c2f02cdfef2006b623dabc71049a2375

  echo 'allow hal_gnss_default vndbinder_device:chr_file rw_file_perms;' | tee --append ~/'android/lineage-15.0/device/moto/shamu/sepolicy/hal_gnss_default.te' > '/dev/null'

===== Tweaks =====

  * If this file doesn't exist, this is likely being ran on fresh sources, and requires [[#breakfast | breakfast]] to be served first
  * Place this at the **top** of the file underneath the copyright ((this ensures the custom ''PRODUCT_PROPERTY_OVERRIDES'' are used, [[https://groups.google.com/d/msg/android-building/Y8Z1hWqL0lY/1NytPiDGg9oJ | see comment]]))
