android - 尝试在 Android 上运行我的 React Native 应用程序时出错

Question

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。现在我正在尝试第一次在 Android 上构建和测试该应用程序。问题是，我在尝试运行我的应用程序的 Android 版本时不断出错。经过数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。我让那部分工作，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 Assets 、样式、源 JS 文件和 package.json 文件粘贴到新项目中，运行 npm install然后我在运行 react-native run-android 时得到了与原始项目中完全相同的错误消息。 .
完整的错误信息在这里:

如果您知道该怎么做或遇到类似问题，请告诉我!

Answer 1

我遇到了同样的问题，并通过卸载 react-native-video (npm uninstall --save react-native-video) 暂时解决了这个问题。这不是一个很好的答案，因为我需要那个组件，但我还没有完整的解决方案。我想不知何故 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，您需要像这样在所有项目(而不是构建依赖项)中添加存储库“jcenter()”...

allprojects {
    repositories {
        mavenCentral()
        mavenLocal()
        jcenter()
}
