我正在使用：
"react": "^16.5.2",
"react-native": "0.57.1",
我像这样修改了我的应用程序的 build.gradle
ext.react = [
entryFile: "index.js",
bundleInRelease : true,
resourcesDirRelease : "src/main/res"
]
apply plugin: 'com.android.application'
import com.android.build.OutputFile
//using custom react gradle here to get around https://stackoverflow.com/questions/52464842/react-native-duplicate-resources
apply from: "../react.gradle"
//apply from: "../../node_modules/react-native/react.gradle"
apply from: "../../node_modules/react-native-code-push/android/codepush.gradle"
然后我的自定义 react.gradle 看起来像这样
import org.apache.tools.ant.taskdefs.condition.Os

def cliPath = config.cliPath ?: "node_modules/react-native/local-cli/cli.js"

return thing ? file(thing) : null;
