反编译的 APK，Catlog "ClassNotFound" 错误

Posted 2023-04-19

【中文标题】反编译的 APK，Catlog "ClassNotFound" 错误

【英文标题】：Decompiled APK, Catlog "ClassNotFound" Errors

【发布时间】：2016-05-14 17:46:30

【问题描述】：

您好，我正在尝试为我的小米易相机改造一个应用程序，以便在相机电池电量不足时推送通知。该应用程序具有执行此操作的所有功能，只是没有我需要的功能。所以我使用APKStudio反编译并导入到eclipse中，但是我得到了一堆ClassNotFound错误。

我认为这是因为 lib 实际上由 .smali 而非 .class 组成。但我不是 100% 确定。

这是目录：

看起来没有像 ProGuard 之类的反反编译。

【参考方案1】：

如果您想为应用添加新功能，您必须学习SMALI，无法将APK完全转换为JAVA。我从来没有用过APKStudio，但我可以推荐你dex2jar或APKtool，在THIS网站你可以找到如何重新解码和构建APP的推荐。

【讨论】：

嗯尝试这种方式，但只是解码和构建而不进行更改，它会在模拟器中吐出“失败 [INSTALL_FAILED_NO_MATCHING_ABIS]”

编辑：也适用于原始 apk。我想这是模拟器设置的问题

好吧，我认为在使用 ARM 设置新的虚拟设备后它可以工作，但我想我用原始 apk 测试了两次。我在手机上使用teamviewer，可能忘记了。无论如何，它会抛出 [INSTALL_PARSE_FAILED_UNEXPECTED_EXCEPTION] 即使我没有进行任何更改并在反编译后直接重建。使用“apktool d test.apk”进行反编译，使用“apktool b -c test”使用原始证书/签名重新编译。

上次更新：再次使用 APKStudio，这次正确设置了签名部分，一切正常。不知道为什么 -c 标志不适用于 apktool。
