## How to

### Setup

#### ~~NDK Sanitizers~~

It won't be used anymore.

```bash

cd ${ANDROID_NDK_HOME}/build/tools

    INSTALL_PATH=/tmp/llvm/prebuilt/"$(echo $(uname -s)-$(uname -m) | tr '[:upper:]' '[:lower:]')"

    ./make_standalone_toolchain.py --arch=arm64 --api=27 --stl=libc++ --install-dir=${INSTALL_PATH} --force

cd ${INSTALL_PATH}

    tree -L 2 ./lib64/clang/9.0.0/lib

```

### Build

The build step uses [Gradle 7.2.0+](https://docs.gradle.org/current/userguide/userguide.html). If you don't know how to use it, latest [Android Studio](https://developer.android.com/studio/) can do the work.   

```console

$ git clone https://github.com/luncliff/Muffin

$ cd ./Muffin

$ gradle clean assemble

```

### Test

Connect your device and run the test with Gradle.

Please reference the [test codes](./android/test/).

```console

$ gradle connectedAndroidTest   # Run test

```
