Compile Android SDK

Make Android SDK

A : Make Android SDK


STEP1: Example for extract the part1 and part2 rar files
root# unrar x -e HiSTBAndroidV800R001C00SPC020.tar.part1.rar
resutls -> HiSTBAndroidV800R001C00SPC020.tar.gz
STEP2: Download the Android SDK through
root# sudo apt -y install git
root# repo init -u https://android.googlesource.com/platform/manifest -b android-8.0.0_r4
root# git config --global user.email "[email protected]"
root# git config --global user.name "SAURAV"
root# repo init -u https://android.googlesource.com/platform/manifest -b android-8.0.0_r4
root# repo sync -j8
or
Copy from harddisk
STEP3: Patching the HISI SDK
copy both SDK20 and SDK21
{HiSTBAndroidV800R001C00SPC020.tar.gz and
HiSTBAndroidV800R001C00SPC021.tar.gz}
root# tar -xvzf HiSTBAndroidV800R001C00SPC020.tar.gz
root# tar -xvzf HiSTBAndroidV800R001C00SPC021.tar.gz
root# cp -rf HiSTBAndroidV800R001C00SPC020/* $yourAndroidPath/
root# cp -rf HiSTBAndroidV800R001C00SPC021/* $yourAndroidPath/
STEP4: Download and copy the linux source
Then copy the linux linux-4.9.44.tar.gz into the following path and you can download the
linux tar file in path www.kernel.org/pub/linux/kernel/v4.x/linux-4.9.44.tar.gz
root# cp -rf linux-4.9.44.tar.gz \
$yourAndroidPath/device/hisilicon/bigfish/sdk/third_party/open_source/
Once above all done your SDK setup ready.


B : Setup the environment
STEP1: Install these apt
root# sudo apt-get install git make zlib1g-dev:i386 cpp gcc-multilib \
g++ g++-4.8-multilib cpp-4.8 g++-4.8 gcc-4.8 binutils gnupg flex \
lib32ncurses5-dev bison gperf build-essential zip curl libc6-dev \

x11proto-core-dev libx11-dev lib32readline6-dev zlib1g-dev \
lib32z-dev libgl1-mesa-dev g++-multilib tofrodos gettext \
libxml2-utils xsltproc u-boot-tools mingw-w64
STEP 2: Then Install JAVA JDK 1.8 as we are going to use Android 8.0
root# sudo apt-get install openjdk-8-jdk
Then update the following path in /etc/profile
export JAVA_HOME="/usr/lib/jvm/java-1.8.0-openjdk-amd64"
export PATH="/usr/lib/jvm/java-1.8.0-openjdk-amd64/bin":$PATH
STEP 3: Replace the system shell with bash.
root# sudo rm /bin/sh;sudo ln -s /bin/bash /bin/sh
STEP 4: Add the s permission to mknod chmod chown
root# sudo chmod a+s /bin/mknod
root# sudo chmod a+s /bin/chmod
root# sudo chmod a+s /bin/chown


C : Compile the environment
STEP 1: Compile the source code
to make all image:
---------------------------------
root# cd $yourAndroidPath/
root# source build/envsetup.sh
root# lunch
and choose Hi3798MV200-eng which is in option 30
root# make bigfish -j32 2>&1 | tee bigfish.log
to make boot:
---------------------------------
make hiboot -j32 2>&1 | tee hiboot.log
following image is compiled:
fastboot.bin
to make kernel:
---------------------------------
root#make kernel –j32 2>&1 | tee kernel.log
following image is compiled:
kernel.img
to make system for Emmc:
---------------------------------
root#make ext4fs -j32 2>&1 | tee ext4fs.log
following image is compiled:
system.ext4
userdata.ext4

cache.ext4
kernel.img
to clean:
---------------------------------
root# make clean
once this done all the images will be compiled.
STEP 2: Compiled Images
To verify the images go to below path:
root# cd $yourAndroidPath/out/target/product/Hi3798MV200/Emmc/

Note:
please follow all the commands following with root#
