### 在Android上执行

#### 1. 在模拟器上执行
#### 1. 创建模拟器（如果使用真机则跳过此步骤）

```shell
# 创建Android avd (armv8)
$ echo n | avdmanager create avd -f -n myarmv8 -k "system-images;android-24;google_apis;arm64-v8a"
# 启动Android armv8 emulator
$ ${ANDROID_HOME}/emulator/emulator -avd myarmv8 -noaudio -no-window -gpu off -verbose &

# armv7版本如下：
# $ echo n | avdmanager create avd -f -n myarmv7 -k "system-images;android-24;google_apis;armeabi-v7a"
# $ ${ANDROID_HOME}/emulator/emulator -avd myarmv7 -noaudio -no-window -gpu off -verbose &
```
#### 2. 上传编译文件到手机上

键盘上`crtl+q+p`同时摁下，切换到容器外（容器还在后台运行），将刚刚编译出的程序`adb push`到手机上。USB线连接手机，确保`adb devices`可以找到手机设备。
