+# HADK for Sony XZ2
+
+This is based on https://sailfishos.org/wiki/Sailfish_X_Xperia_Android_9_Build_and_Flash and adjusted for Tama 
+platform and, when needed, XZ2 device (akari) of this platform.
+
+## .hadk.env
+
+```
+export VENDOR="sony"
+export DEVICE="h8216" 
+export HABUILD_DEVICE=akari 
+export FAMILY=tama 
+export ANDROID_FLAVOUR=pie
+export HAVERSION="sony-"$FAMILY"-aosp-"$ANDROID_FLAVOUR
+# Set arch to armv7hl even if you are porting a 64bit device
+export PORT_ARCH="armv7hl"
+```
+
+## Setting up sources
+
+```
+HABUILD_SDK $
+
+sudo apt-get install libssl-dev
+sudo mkdir -p $ANDROID_ROOT
+sudo chown -R $USER $ANDROID_ROOT
+cd $ANDROID_ROOT
+git clone https://github.com/sailfishos-sony-tama/droid-hal-sony-$FAMILY-$ANDROID_FLAVOUR .
+git submodule init
+git submodule update
+cd hybris/mw/libhybris
+git submodule init
+git submodule update
+cd -
+ln -s ../dhd rpm/
+mv rpm dhd-rpm
+```
+
+Until we get tama branch or unify it all under one with ganges, proceed as follows:
+
+```
+repo init -u git://github.com/mer-hybris/android.git -b sony-ganges-aosp-pie -m tagged-manifest.xml
+mkdir $ANDROID_ROOT/.repo/local_manifests
+```
+
+Add the following content to $ANDROID_ROOT/.repo/local_manifests/$DEVICE.xml
+
+```XML
+<?xml version="1.0" encoding="UTF-8"?>
+<manifest>
+  <remote fetch="https://github.com/sailfishos-sony-tama" name="hybris-tama"/>
+  <project name="droid-src-sony-tama-pie" path="rpm" remote="hybris-tama" revision="master"/>
+</manifest>
+```
+
+Comment out a line below in $ANDROID_ROOT/.repo/manifest.xml
+```
+<project name="droid-src-sony-ganges-pie" path="rpm" 
+```
+using `<!-- ... !-->` notation.
+
+Continue with syncing repo and build
+
+```
+repo sync -j8 --fetch-submodules
+mv rpm droid-src
+ln -s droid-src/patches .
+droid-src/apply-patches.sh --mb
+mv dhd-rpm rpm
+./setup-sources.sh --mb
+
+source build/envsetup.sh
+export USE_CCACHE=1
+lunch aosp_$DEVICE-user
+make -j$(nproc --all) hybris-hal
+```
