Instead of the standard apktool, I am going to use 7z to unpack and pack the APK.

Most importantly, this tool can compile CIL code, which enables you to easily make changes in the studied files. exe into C# or CIL code (Common Intermediate Language is a ‘high-level assembler’ used by the .NET virtual machine – an intermediate language developed by Microsoft for the .NET Framework platform). Simple Assembly Explorer is a rather old, but still efficient utility making it possible to decompile. In my case, the compilation function didn’t work: the program was unable to link together the Mono and Android namespaces. It must be noted that not all of its functions always work (except for decompiling): much depends on the specific situation.

dotPeek main windowĭnSpy is used to decompile, edit, compile, and debug. In my opinion, dotPeek offers the most handy navigation through the decompiled code, which makes it the optimal tool for algorithm analysis. The program makes it possible to decompile and examine.

Net, I always use three tools.ĭotPeek by JetBrains. Names of many libraries contain the word Xamarin so, it becomes clear where such uniformity comes from: the main program code is written in C# and is located in a DLL library only boilerplate pieces of code designed for interaction between the Mono runtime and the Android Runtime (ART) virtual machine are written in Java.Įnough theory, let’s get to work! Selecting tools

zip, then the assemblies folder immediately catches your eye: first, such folders are uncommon for ordinary mobile apps and second, it contains numerous DLL libraries. This makes me thinking that something is wrong with this APK.
