Creating custom function in sqlite3 in android

Question

I need to add a custom function in sqlite3 in android app to calculate distance between two geo coordinate. i have found a c function which can be added as a custom function in sqlite3.

I am using NDK to compile sqlite3 files to create .so file. But I am not sure where to put code for my custom function which is also written in C and where to call sqlite3_create_function(...) which attaches custom function with sqlite so I can use my custom function in sqlite queries.

It seems like, in general and for all purposes, you can´t! but, there´s a workaround if you can install your own sqlite How can I create a user-defined function in SQLite?
