Question

我使用dex2jar工具来解压缩apk文件，所有代码都可以正确解编译，但是这个方法

怎么了？

Answer 1

怎么了？

没有错。反编译器经常遇到代码太复杂或者被混淆的问题（故意难以反编译......）

你能做些什么？并不多......除了用手反编译自己的代码。（但这并不容易。首先，您需要弄清楚异常处理的范围，并重新创建try / catch / finally块。）

Answer 2

它或者只是反编译器的限制，或者可能是这种方法被混淆了。虽然，通常整个.apks都是混淆的，而不仅仅是一种方法。也许如果你说这是哪个.apk，那就更有可能提出答案。

为什么不能从android apk解编译这个方法？
