Running the script on smali files using the local registers directive. A user basic interface to make the injection of custom code more friendly.įor all the details regarding reverse engineering of Android apps refers to this link:.The possibility to inject the code to a specific method.Modify the inject_code methods parameters inside of the inject.py file.Copy the smali method inside of the /files/M圜ustomClass.smali file.To inject its custom code a user has to follow this procedure: Smali-code-injector deals with the register dependancies and properties to make the code injection easy and automatic. Indeed a user can use smali-code-injector to inject its own custom code. However, the power of this script resides on its high customizable possibilities. The basic purpose of this script is to add a trace to all the methods of a given Android app, to help to debug or reverse engineer it. For this task, I highly recommand to use smali/baksmali which are respectively an Android assembler/de-assembler natively present in the Santoku Linux distribution. Therefore an user needs first to de-assembly an app in order to get its. The code injection is performed on the assembly level of an app. Script to perform code injection in Android apps.
