未找到 SDK 位置.使用 ANDROID_SDK_ROOT 环境变量或通过在项目的本地属性文件中的C:\Users\hp\Desktop\Reactprojects\Makerobos\android\local.properties"中设置 sdk.dir 路径来定义位置.
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 'C:\Users\hp\Desktop\Reactprojects\Makerobos\android\local.properties'.

推荐答案
您的 SDK 路径不正确，需要在以下文件中添加正确的路径:萨项目 >安卓 >local.properties
Your SDK path is not correct you need to add a correct path in the below file: sa project > android > local.properties
添加如下示例的路径:
sdk.dir = /Users/admin/Library/Android/sdk
添加后使用以下命令:
1. cd android/
2. ./gradlew clean
3. cd ..
4. Command: react-native bundle --platform android --dev false --entry-file indexcsasa.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res
csacs
5. react-native run-android
