API function 3. API call sequence are defined and declared .I want to print only API functions and API call sequence using python .

Answer 1

The question asks about parsing smali files, but that is unlikely to be what you actually want. Assuming your goal is to analyze Android applications, you need to parse dex files. Luckily, there is a tool written in Python called Enjarify that contains a dex parser. It's not designed to be used as a library, so it will take a little bit of work to integrate, but you should be able to figure it out pretty easily. You can start by looking at parsedex.py .

Assuming that you really do want to parse smali files for some reason, things are a lot harder, as smali is a file format defined by the smali tool, which is written in Java. However, you could use Jython to call it from Python.

Answer 2

Following is Syntax that is used to identify .Smali Function calls

1. invoke-super vx, vy, : invokes the parent classes method in object vx, passing in parameter(s) vy.
2. invoke-direct vx, vy : invokes a method in object vx with parameters vy, … without the virtual method resolution.
3. invoke-virtual vx, vy : invokes the virtual method in object vx, passing in parameters vy.
