MODIFYING MOBILE APPLICATION BINARIES TO CALL EXTERNAL LIBRARIES

A method includes determining a system library method based on a configuration file in an application library. The method also includes generating a wrapper method for the system library method, wherein the wrapper method includes a first instruction to invoke the system library method, and a second instruction to invoke a method in an external library. The method further includes replacing a third instruction that invokes the system library method with a fourth instruction that invokes the wrapper method. A binary class in a plurality of binary classes in the application library comprises the third instruction.
