我已经构建了React原生应用程序，并用iOS设备进行了数月的测试和故障排除.现在，我正试图在Android上首次构建和测试该应用程序.问题是，我一直在try 运行Android版本的应用程序时出错.经过数小时的调试和故障排除，我试图创建一个新的RN项目，看看它能否在我的模拟器和设备上运行.我让那部分工作，然后我想复制/粘贴我现有应用程序项目的文件到新项目中.
我粘贴了我现有的资源、样式、源JS文件和包.将json文件放入新项目，运行npm install，然后我得到了与运行react-native run-android时在原始项目中完全相同的错误消息.
完整的错误信息如下:
error Failed to install the app. Make sure you have the Android development environment set up: https://reactnative.dev/docs/environment-setup.

我try 在android文件夹中运行./gradlew clean次，但没有任何运气.我的身材.gradle文件如下所示:
