able to generate a shared library support Android platform.
- need an [android SDK](https://developer.android.com/studio). Go and get the "Command line tools only"
- look for a command named *sdkmanager* and download below components. version numbers might need to check and pick others
- "build-tools;29.0.3"
- "cmake;3.10.2.4988404"
- "ndk;21.0.6113669"
- "patcher;v4"
- "platform-tools"
- "platforms;android-29"
- add bin/ of the downloaded cmake to $PATH
- export ANDROID_SDK_HOME=/the/path/of/downloaded/sdk/
- export ANDROID_NDK_HOME=/the/path/of/downloaded/sdk/ndk/
- ready to go
Use such commands, you are able to compile with default configurations. Any compiling requirement should be satisfied by modifying product-mini/platforms/android/CMakeList.txt. For example, chaning ${WAMR_BUILD_TARGET} in CMakeList could get different libraries support different ABIs.
``` shell
$ cd product-mini/platforms/android/
$ mkdir build
$ cd build
$ cmake ..
$ make
$ # check output in distribution/wasm
$ # include/ includes all necesary head files
$ # lib includes libiwasm.so
```

-------------------------
[Docker](https://www.docker.com/) will download all the dependencies and build WAMR Core on your behalf.

Since ui_app incorporated LittlevGL source code, so it needs more RAM on the device to install the application.
It is recommended that RAM SIZE not less than 420KB.
In our test use nucleo_f767zi, which is not supported by Zephyr.
However, nucleo_f767zi is almost the same as nucleo_f746zg, except FLASH and SRAM size.
So we changed the DTS setting of nucleo_f746zg boards for a workaround.</br>
It is recommended that RAM SIZE not less than 380KB.
In our test use nucleo_f767zi, which is supported by Zephyr.
