【问题描述】：
我已关注these instructions 搭建环境。我在 Ubuntu 20.04 上。
我已经添加了~/.bashrc的路径：
export ANDROID_HOME=$HOME/Android/Sdk
export PATH=$PATH:$ANDROID_HOME/emulator
export PATH=$PATH:$ANDROID_HOME/tools
export PATH=$PATH:$ANDROID_HOME/tools/bin
export PATH=$PATH:$ANDROID_HOME/platform-tools
我已经检查了 Android Studio，~/Android/Sdk 似乎是正确的。
我从 Ubuntu 软件中心 (snap) 安装了 OpenJDK 和 Android Studio，并使用 npx react-native init AwesomeProject 创建了一个新项目。
然后我运行 npx react-native start 来启动 Metro。
我打开了一个运行 API 29 的虚拟设备 (Pixel XL)。
我尝试使用npx react-native run-android 启动应用程序，但得到以下输出：
（输出相当大，所以我只包含了初始行和最后一行以保持可读性）
