我已经构建了我的 React Native 应用程序,并使用我的 iOS 设备进行了几个月的测试和故障排除。现在我第一次尝试在 Android 上构建和测试该应用程序。问题是,我在尝试运行 Android 版本的应用程序时不断遇到错误。经过几个小时的调试和故障排除后,我尝试创建一个新的 RN 项目,看看它是否可以在我的模拟器和设备上运行。我让该部分工作,然后我想将现有应用程序项目的文件复制/粘贴到新项目中。
我将现有的资产、样式、源 JS 文件和 package.json 文件粘贴到新项目中,然后运行npm install
然后当我运行时,我最终得到了与原始项目中完全相同的错误消息react-native run-android
.
完整的错误消息在这里:

我试过跑./gradlew clean
在 android-folder 中没有任何运气。我的 build.gradle 文件如下所示:

如果您知道该怎么做或者您遇到过类似问题,请告诉我!
我遇到了同样的问题,并通过卸载react-native-video(npm uninstall --save react-native-video)暂时解决了该问题。这不是一个很好的答案,因为我需要该组件,但我还没有完整的解决方案。我认为不知何故 com.yqritc:android-scalablevideoview:1.0.4。 React-native-video 需要但已丢失或删除。欢迎其他想法。
更新:已解决!在 Android 文件夹中的 build.gradle 中,您需要在所有项目中(而不是在构建依赖项中)添加存储库“jcenter()”,如下所示...
allprojects {
repositories {
mavenCentral()
mavenLocal()
jcenter()
}
}
