Android Studio 3.1.2升级后遇EOCD Signature not found问题求助

我之前升级Android Studio版本时也碰到过一模一样的问题，这个错误本质是JNI库合并时读取损坏的Zip文件导致的，和multidex的关联其实是升级后Gradle插件对JNI文件处理逻辑变化引发的。给你几个亲测有效的解决步骤：

1. 彻底清理缓存与构建产物 #

这是最容易见效的第一步，很多时候都是缓存文件损坏引发的问题：

• 执行命令行清理：Windows下运行 gradlew clean，Mac/Linux运行 ./gradlew clean
• 删除项目根目录下的 .gradle 文件夹和 app/build 目录
• 重启Android Studio，点击顶部菜单栏的「File -> Sync Project with Gradle Files」重新同步项目

2. 检查并修复损坏的依赖库 #

从错误日志能看到，问题出在 adal-1.13.2.aar 的JNI目录下：

java.io.IOException: Failed to read zip file 'C:\Users\袛懈屑邪\.gradle\caches\transforms-1\files-1.1\adal-1.13.2.aar\0609b8bbdaebc86f749d40642893ae87\jni'

• 手动定位到这个目录，尝试打开其中的Zip文件，如果无法正常打开说明缓存已损坏，直接删除整个 adal-1.13.2.aar 对应的缓存文件夹
• 建议把adal库升级到最新稳定版本，旧版本的AAR可能和3.1.2版本的Gradle插件存在兼容性问题

3. 调整JNI打包配置 #

在 app/build.gradle 中添加打包选项，避免合并异常的JNI文件：

android {
    defaultConfig {
        multiDexEnabled true // 确保你已经开启了multidex
        // 其他配置...
    }

    packagingOptions {
        pickFirst '**/*.so' // 优先选择第一个出现的so文件，避免冲突
        // 如果能定位到具体损坏的so文件，可以直接排除
        // exclude '**/libadal.so'
    }
}

同时确认multidex配置完整：

• 如果你的Application没有继承 MultiDexApplication，需要在 attachBaseContext 方法中手动初始化：

@Override
protected void attachBaseContext(Context base) {
    super.attachBaseContext(base);
    MultiDex.install(this);
}

4. 调整Gradle插件版本 #

3.1.2版本的Android Gradle插件存在一些已知的JNI合并问题，你可以尝试：

• 升级到同系列的稳定版本，比如3.1.4
• 或者暂时降级到3.0.1版本，看是否能绕过这个错误
