== '''Android Compilation Environment Construction''' ==

<br>

=== '''Download SDK compression package''' ===

<br>

* '''Android 6.0'''

Download the compression packages, corresponding to OrangePi_4G-IoT_Android 6.0_V1.0.tar.gz.00, OrangePi_4G-IoT_Android 6.0_V1.0.tar.gz.01, OrangePi_4G-IoT_Android 6.0_V1.0.tar.gz.14, a total of 15 volume compression packages. After obtaining the volume compressed packages, place all the compressed packages in the same directory, such as<br>

<br>

'''Create directory:'''<br>

mkdir OrangePi_4G-IOT_Android6.0 <br>

'''Copy Volume Compression Packet:'''<br>

cp -rf OrangePi_4G-IoT_Android6.0_V1.0.tar.gz.* <br>

OrangePi_4G-IOT_Android6.0/<br>

'''Merge Compression Packet:'''<br>

cat OrangePi_4G-IoT_Android6.0_V1.0.tar.gz.* > <br>

OrangePi_4G-IOT_Android6.0.tar.gz<br>

'''Unzip:'''<br>

tar xzvf OrangePi_4G-IOT_Android6.0.tar.gz

</div>

* '''Android 8.1'''

After downloaded compression package, you will have 11packages named x00, x01, x02, x03 ...x10.Put packages on the same directory like the following:

Create directory<br>

mkdir OrangePi_4G-IOT_Android8.1 <br>

Copy compress package<br>

cp -rf x00 x01 x02 ... x10 <br>

Merge compression package<br>

cat x*>OrangePi_4G-IOT_Android8.1.tar.gz <br>

Decompression<br>

tar xzvf OrangePi_4G-IOT_Android8.tar.gz

=== '''Construct Compilation Environment''' ===

<br>

It could also refer to Google file: [http://source.android.com/source/initializing.html

<span style="color:#6600ff;">http://source.android.com/source/initializing.html</span>]<br>

<br>

* '''Install JDK'''

Compilation of Android6.0 is based on JAVA7, it needs to first install OpenJDK before compilation.<br>

<br>

Command for installing:

sudo apt-get install openjdk-7-jdk

</div>

<br>

Configure environment variable of JAVA, here is the path for installation:<br>

<br>

/usr/lib/jvm/java-7-openjdk-amd64<br>

<br>

It could configure on the terminal with the following command:<br>

<br>

export JAVA_HOME=/usr/lib/jvm/java-7-openjdk-amd64 <br>

export PATH=$JAVA_HOME/bin:$PATH<br>

export CLASSPATH=.:$JAVA_HOME/lib:$JAVA_HOME/lib/tools.jar

</div>

* '''Install Software Package'''

For Ubuntu12.04:

sudo apt-get update<br>

sudo apt-get install git-core gnupg flex bison ccache gperf libsdl1.2-dev libesd0-dev libwxgtk2.6-dev build-essential zip curl libncurses5-dev zlib1g-dev valgrind libc6-dev lib32ncurses5-dev x11proto-core-dev

libx11-dev lib32readline-gplv2-dev lib32z1-dev libgl1-mesa-dev gcc-4.4 g++-4.4 g++-4.4-multilib g++-multilib mingw32 tofrodos python-markdown libxml2-utils xsltproc wine

</div>

<br>

For Ubuntu14.04：

sudo apt-get update<br>

sudo apt-get install git-core gnupg flex bison ccache gperf libsdl1.2-dev libesd0-dev libwxgtk2.8-dev build-essential zip curl libncurses5-dev zlib1g-dev valgrind libc6-dev lib32ncurses5-dev x11proto-core-dev

libx11-dev lib32readline-gplv2-dev lib32z1-dev libgl1-mesa-dev g++-multilib g++-4.8-multilib mingw32 tofrodos python-markdown

libxml2-utils xsltproc libc6-dev-i386 lib32z1 lib32ncurses5 lib32bz2-1.0 lib32readline-gplv2-dev wine

</div>

<br>

We could process to SDK compilation after finished the above.<br>

<br>

=== '''Compilation of SDK Source Code''' ===

<br>

There are many compilation shell scripts for development.<br>

<br>

* '''Android 6.0'''

<br>

The directory would be: SDK/code/orangepi/scripts<br>

<br>

$ cd code/orangepi/scripts<br>

$ ls<br>

anr_LM.sh auto.sh clean.sh codegen.sh init_project.sh tar_img.sh

</div>

auto.sh is automatically compilation script<br>

clean.sh automatically scavenging the compiled result script<br>

<br>

On the directory of code/orangepi/scripts, execute the automatically compilation script:

$ ./auto.sh IoT_bd6737m_35g_b_m0_op_smt_hd720_pcb_v2 v00 eng

</div>

The meaning of the parameter is:<br>

#$1 project_info [eg: IoT_bd6737m_35g_b_m0_op_smt_hd720_pcb_v2] <br>

#$2 version_info [eg: v00 v01 ...]<br>

#$3 compile_mode [eng:user userdebug eng]

* '''Android 8.1'''

<br>

The directory would be: SDK/code/orangepi/scripts<br>

<br>

$ cd code/orangepi/scripts<br>

$ ls<br>

anr_LM.sh auto.sh clean.sh codegen.sh init_project.sh tar_img.sh

</div>

auto.sh--scripts for automatic compilation<br>

clean.sh--scripts for automatically cleaning the compiled result<br>

<br>

On the directory of code/orangepi/scripts, execute automatic compilation scripts:

$ ./auto.sh IoT_k37mv1_bsp_ry_smt_hd720_pcb_v2 v00 eng

</div>

Definition of the three parameters:<br>

#$1 project_info [eg: IoT_k37mv1_bsp_ry_smt_hd720_pcb_v2] <br>

#$2 version_info [eg: v00 v01 ...]<br>

#$3 compile_mode [eng:user userdebug eng]<br>

<br>

Execute command to compile:<br>

source build/envsetup.sh<br>

luncher >full_k37mv1_bsp-eng<br>

make -j4<br>

<br>

'''Module compilation'''

<br>

Here would take an example of only compilation launcer:<br>

mm packages/apps/Launcher3/ or enter into directory of packages/apps/Launcher3/, execute mm<br> Please note that some modules depend on the relationship of package, you need to run mma.

<br>

=== '''Generated Firmware''' ===

<br>

* '''Android6.0'''

After compiled, the firmware will gather in the directory of: code/IoT_op_smt_hd720_pcb_v2, pack it and name it like the following: IoT_op_smt_hd720_pcb_v2_v00_eng_20180126140300.tar.gz

$ tree IoT_op_smt_hd720_pcb_v2 IoT_op_smt_hd720_pcb_v2<br>
