If you can compile the functions in question then you can generate C code. To check if the compiled code needs a call back to the M- evaluator, I usually use CompilePrint and see if there is a call to MainEvaluate. > For example, if I have an application meant for use on an Android > device, is it possible for Mathematica to give me all I need to > generate a Java library, or C source code that can be compiled for a > Java device?

Here are some notes on how to build for a different target system CCompilerDriver/tutorial/Compilation#8215639 And the section on setting the compiler.
