每次我尝试构建或清理我的项目时，我都会收到“执行失败的任务'app：mergeDebugResource'”错误。我已多次重新安装Gradle，Java，Android Studio和所有SDK，所以事实并非如此。 StackOverflow上的答案似乎都没有帮助。我正在尝试学习Android开发但不能因为这个错误。请帮忙！
以下是Gradle build --stacktrace的结果：

谢谢！！
在终端窗口中执行此操作，看看，
gradlew clean build --refresh-dependencies
在我的RN应用程序上安装新软件包时遇到错误。我通过运行修复了错误
cd android/ && ./gradlew clean build --refresh-dependencies`
然后
cd ../
再次
react-native run-android
