使用gradlew assembleRelease打包React Native APK失败求助

问题描述 #

过去两周尝试生成Release APK一直失败，执行gradlew bundleRelease生成bundle完全正常，但运行gradlew assembleRelease时报错，错误指向:react-native-fetch-blob:verifyReleaseResources任务失败，出现大量Android资源找不到的错误。

解决方案 #

方案1：替换为维护中的分支库 #

react-native-fetch-blob已停止维护，无法适配高版本Android SDK。建议替换为社区维护的rn-fetch-blob：

1. 卸载原库：

npm uninstall react-native-fetch-blob
# 或 yarn remove react-native-fetch-blob

2. 安装替代库：

npm install rn-fetch-blob
# 或 yarn add rn-fetch-blob

3. 替换代码中的导入：将import RNFetchBlob from 'react-native-fetch-blob'改为import RNFetchBlob from 'rn-fetch-blob'

方案2：强制统一AndroidX依赖版本 #

如果不想替换库，可在android/build.gradle中添加配置，强制react-native-fetch-blob使用与项目一致的AndroidX版本：
在allprojects块内添加：

subprojects {
    if (project.name.contains("react-native-fetch-blob")) {
        buildscript {
            ext {
                compileSdkVersion = rootProject.ext.compileSdkVersion
                buildToolsVersion = rootProject.ext.buildToolsVersion
                targetSdkVersion = rootProject.ext.targetSdkVersion
            }
        }
        dependencies {
            implementation 'androidx.appcompat:appcompat:1.6.1'
            implementation 'androidx.core:core:1.9.0'
        }
    }
}

方案3：清理缓存并重新构建 #

完成上述任一方案后，执行以下命令清理缓存：

cd android
./gradlew clean
rm -rf ~/.gradle/caches
cd ..
npm install # 或 yarn install

然后重新尝试生成Release APK：

cd android
./gradlew assembleRelease
