问题是，我在使用 Allatori Java Obfuscator 生成Signed APK 时遇到错误。我尝试了不同的技巧，例如 Invalidate and Clear cache/Restart，通过删除构建文件夹，重建项目，Strings，甚至尝试比较包名称，类命名约定，可能的 jars，deprecated methods 或 classes 但没用。! Multi Dex 也已启用。!我尝试了所有可能的解决方案，但无法生成已签名的 APK。

最佳答案

据我所知，由于 Allatori 混淆，您正在使用大量库并使用 Allatori Java 混淆器，您的 Java 代码未正确转换为字节码，这就是您无法生成签名 apk 的原因。尝试快速删除构建文件、gradle 文件并多次使项目无效并重新启动

希望这对你有帮助:)
