1、无法远程调试，链接不上远程调试服务器
报错：unable to connect with remote debugger
解决方案：
- Press
Cmd + Mon emulator screen - Go to
Dev settings > Debug server host & port for device - Set
localhost:8081 - Rerun the android app:
react-native run-android
将调试器改为localhost:8081，重启服务即可。
2、Could not read path 'C:\MyApp\android\app\build\intermediates\incremental\mergeDebugResources\merged.dir\values-az-rAZ'
Have you tried to run:
cd android && gradlew clean
cd .. && react-native run-android
This can solve some problems on Android :)
Or if this doesn't work, you can try to remove the android/app/build folder altogether.
3、SDK location not found. Define location with an ANDROID_SDK_ROOT environment variable or by setting the sdk.dir path in your project's local properties file at 'F:\react\AwesomeProject\android\local.properties'
解决方案：在android文件夹下面新建 local.properties 文件，在文件中输入以下路径：
For windows users:
sdk.dir=C\:\\Users\\UserName\\AppData\\Local\\Android\\sdk
For Mac users:
sdk.dir = /Users/USERNAME/Library/Android/sdk
For Linux (Ubuntu) users:
sdk.dir = /home/USERNAME/Android/Sdk
Where USERNAME is your linux username(Linux paths are case-sensitive: make sure the case of S in Sdk matches)
In case if this doesn't work, add ANDROID_HOME variable in "Environment Variables" as C:\Users\USER\AppData\Local\Android\Sdk
