How to emulate object movement by google maps coordinates?

Question

Android

Help! I'm burning! There is a list of coordinates. It is necessary that the typewriter move along them (well, I made it a marker). This is a simulation of movement, no real location tracking is needed, you can get by with a handler. It is also necessary that the machine is always turned towards the next coordinate. How to implement this can be a schematic explanation. You just need to add up in your head how to make the movement smooth.

rotation - read angle between current and future coordinate vectors

Answer 2

regular linear function: (x-x0)/(x1-x0)=(y-y0)/(y1-y0)
