Question (I don't know how Android works) -- how is there even a "frame rate" for a map that isn't moving? Shouldn't it not be doing anything at all when nobody

Question (I don't know how Android works) -- how is there even a "frame rate" for a map that isn't moving? Shouldn't it not be doing anything at all when nobody is touching anything?

> could align map north with compass north Maybe the map turns as you turn so as to maintain compass north.

  Just to confirm: yes, that is exactly what I meant.

    Oh I see, it was supposed to align in real time, I missed that. Thanks.

I assume you might need it for the “person” icon while the user moves around the city?

Most maps these days are rendered via OpenGL (or Metal) and in those cases you still manually flip buffers and order GPU to render a frame. It's possible to control this process to avoid exessive power usage. Of course, for most developers that might mean to not update/invalidate() a map view constantly :)
