Sign the APK (to verify the identify of the author all packages must be signed) and finally install it.

Once all is over, use apktool again to rebuild the APK.

Alternatively, write the modification in Java, compile it, decompile it again to Smali, then copy the resulting Smali code over.

Actually modify it by editing the Smali code directly.(This is optional, but can be helpful as Smali is much more difficult to understand.) Extract x from the APK, then use dex2jar and finally a Java decompiler to get (incomplete, often broken, but mostly understandable) Java code.( apktool makes use of smali/baksmali, but makes it much easier to decompile and rebuild APKs, and also takes care of decoding resources like XML files.) Use something like apktool to decompile the APK to Smali.Get the APK (from the web or from the device).What would a developer need to do to modify an app (without access to the source), then? The process is more or less as follows: Also note that the above explanation is a bit simplified, but should be a close analogy while still being easy to understand. However, we usually refer to the format smali understands when we say 'Smali' (think of it as instructions defining every little detail, even if it's not all needed by us humans - it's therefore more verbose than Java). Smali/baksmali is actually an assembler/dissembler for the dex format - that's what it literally means in Icelandic. In other words, any modifications you might make will be for naught since you won't be able to turn it back into an APK again to install it on your device… at least not without a lot of effort. You can go one step further and translate it back to Java, though that process isn't faithful enough - you'll get an understandable result, but chances are you won't be able to translate it the other way around again as some details will be lost along the way. That's where smali comes in, as a more readable but faithful translation. From it, you can get the dex files (usually x) and then try to translate it back to a format you can understand. However, what you do have is the APK, since it's what is installed on your device.

dex files contained inside the application package (or APK).Īt that point, you can't access the original source code anymore (unless you're the developer or the application is open source). A program (the compiler) then 'translates' that code to another format suitable for your device, resulting in. Developers usually use the Java programming language to code Android apps in. If you're not familiar with modding Android applications, you might be wondering what smali is. More seriously… Let's start at the beginning.
