1. Android build
  - Download original android source code ( android-7.1.1_r22 ) from http://source.android.com
    {
      $repo init -u git://10.168.177.185/platform/manifest.git -b android-7.1.1_r22
      $repo sync -cdq -j12 --no-tags
      $repo start android-7.1.1_r22 --all 
    )
  - And, merge the source into the android source code
  - Run following scripts to build android
    a) source build/envsetup.sh
    b) lunch 1
    c) make -j4
  - When you compile the android source code, you have to add google original prebuilt source(toolchain) into the android directory.
  - After build, you can find output at out/target/product/generic

2. Kernel Build  
  - When you compile the kernel source code, you have to add google original prebuilt source(toolchain) into the android directory.
  - Run following scripts to build kernel
  
    a) cd kernel-3.18
    b) mkdir -p out
    c) export PATH=$PATH:$(pwd)/tools/lz4
    d) make -C ../kernel-3.18 O=./out ARCH=arm CROSS_COMPILE=$(pwd)/../prebuilts/gcc/linux-x86/arm/arm-eabi-4.8/bin/arm-eabi- ROOTDIR=../../android  LGE_TARGET_PLATFORM=mt6750 LGE_TARGET_DEVICE=mth8  mth8_spr_us_defconfig -j4
    e) make -C ../kernel-3.18 O=./out ARCH=arm CROSS_COMPILE=$(pwd)/../prebuilts/gcc/linux-x86/arm/arm-eabi-4.8/bin/arm-eabi- ROOTDIR=../../android  LGE_TARGET_PLATFORM=mt6750 LGE_TARGET_DEVICE=mth8  headers_install -j4
    f) make -C ../kernel-3.18 O=./out ARCH=arm CROSS_COMPILE=$(pwd)/../prebuilts/gcc/linux-x86/arm/arm-eabi-4.8/bin/arm-eabi- ROOTDIR=../../android  LGE_TARGET_PLATFORM=mt6750 LGE_TARGET_DEVICE=mth8 -j4
	
	* "-j4" : The number, 4, is the number of multiple jobs to be invoked simultaneously. 
  - After build, you can find the build image(zImage) at out/arch/arm/boot
