您需要删除生成的资源/drawable 并再次生成。

rm -rf android/app/src/main/res/drawable-*
react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res/

并再次编译android react-native run-android

react.gradle 会自动构建您的 javascript 并将您的 javascript 中导入的任何资源复制到构建文件夹中，因此请确保不要react-native bundle手动调用并删除任何文件或文件夹，src/main/res/drawable-*并将src/main/assets/*.bundle以下更改添加到您的app/bundle.gradle

project.ext.react = [
  entryFile      : "index.js", // or index.android.js
  bundleInRelease: true,
  bundleInDebug: true
]

apply from: "../../node_modules/react-native/react.gradle"

注意：请注意一些 react-native 版本在本地有问题cli.js请确保升级到较新的版本或尝试添加以下配置

 project.ext.react = [
    // ...
    cliPath: "node_modules/react-native/local-cli/cli.js"
 ]

[0.57] 丑陋的解决方法

如果您不想回滚 react-native 版本，您可以将 react.gradle 回滚到最后一个工作版本。那对我有用。

将git代码复制到 node_modules/react-native/react.gradle

https://github.com/facebook/react-native/blob/2d9e2f30e17b8e79f2c44ef533ecdd550671304c/react.gradle

如果问题仍然存在，请尝试删除if (isAndroidLibrary)on doLast。

我在用：

"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 config = project.hasProperty("react") ? project.react : [];

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

    return thing ? file(thing) : null;
}

def reactRoot = elvisFile(config.root) ?: file("../../")
def inputExcludes = config.inputExcludes ?: ["android/**", "ios/**"]
def bundleConfig = config.bundleConfig ? "${reactRoot}/${config.bundleConfig}" : null ;

void runBefore(String dependentTaskName, Task task) {
    Task dependentTask = tasks.findByPath(dependentTaskName);
    if (dependentTask != null) {
        dependentTask.dependsOn task
    }
}

afterEvaluate {
    def isAndroidLibrary = plugins.hasPlugin("com.android.library")
    // Grab all build types and product flavors
    def buildTypes = android.buildTypes.collect { type -> type.name }
    def productFlavors = android.productFlavors.collect { flavor -> flavor.name }

    // When no product flavors defined, use empty
    if (!productFlavors) productFlavors.add('')

    productFlavors.each { productFlavorName ->
        buildTypes.each { buildTypeName ->

                def extraArgs = extraPackagerArgs;

您可以尝试清理catch内存并重新安装节点module

watchman watch-del-all
rm -rf node_modules && npm install
rm -fr $TMPDIR/react-*
npm cache clean
npm start -- --reset-cache

这对我有用。
