didi VirtualAPK 项目集成demo

#构建宿主命令

• cd VirtualAPKDemo
• ./gradlew clean assembleRelease
• adb install app/build/outputs/apk/release/app-release.apk

• cd PluginDemo
• ./gradlew clean assemblePlugin
• adb push plugindemo/build/outputs/apk/release/plugindemo-release.apk /sdcard/PluginSub.apk

• Android Q 如果将见插件放到sd中会提示权限错误

   Android 10 Unable to open '/storage/emulated/0/: Permission denied

• 在Android10 中读取sd卡数据时候报这样的错，起初一脸懵逼，权限也加了为什么还报没有权限。这里是Android的新机制，每个应用只能访问如下路径：

    /storage/emulated/0/Android/data/<packageName>/files

Note: 目前宿主项目编译签名文件会提示错误，这里只是验证VirtualAPK 开源框架的接入流程，暂时不去解决
