【问题描述】：
我正在与另一个开发人员一起开发一个项目，它在我克隆主分支后开始发生，所有资产仍然在我的项目文件夹中 assets/ 下，我可以通过导航到该文件夹中字面上看到它们，但是当我运行我的项目（仅限安卓), 我看不到任何正在加载的资产，只有白色背景。当其他开发人员为不同的环境配置添加一些 productFlavours 时，它开始发生。以下是一些我认为与解决此问题有关的相关细节，但我似乎无法做到......
我用来运行我的 android 项目的命令：- npx react-native run-android --variant=DevDebug
我的安卓文件夹：-
下面是我的android/app/build.gradle 文件：-
apply plugin: "com.android.application"

如果有人可以为这个问题提供任何解决方案，那将非常有帮助，如果需要，很乐意提供更多信息！
