How to find source code of native java function call

Question

The Android OS has a class called BinderProxy inside android.os.Binder.java. This class has the following function declaration:

public native boolean transact(int code, Parcel data, Parcel reply, int flags) throws RemoteException;

I want to find out what code is executed when this function is called.

How will I do that ?

Look over here, this is the source code of Binder.cpp, which includes this function.
