Build.Gradle：

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
        repositories {
           jcenter()
        }
     dependencies {
         classpath 'com.android.tools.build:gradle:2.2.3'

         // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
     }

Answer 1

您的stacktrace以:错误：无法找到符号导入com.facebook.React.reactApplication开始，这似乎表明它无法找到React库导入。

我将在Github上为您提供一个答案，请阅读：

https://github.com/transistorsoft/react-native-background-geolocation/issues/294

如果其他人也遇到了同样的问题：确保正确添加了新的存储库。根据Android文档，每个maven repo都应该在自己的maven{}块中。

这就是为什么

maven {
    // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
    url "$rootDir/../node_modules/react-native/android"
    url 'some new extra repo'
}

打破依赖关系。正确的版本是

maven {
    // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
    url "$rootDir/../node_modules/react-native/android"
}
maven {
    url 'some new extra repo'
}

React原生android错误：找不到符号

最后的手段

可能值得创建一个新的测试项目（使用最新版本），比如react-native init anotherproject，看看它是否运行。
