I created custom SurfaceView which contains circles. And I want to rotate this circle using touch events. But I do not understand when thread of SurfaceView must pause and resume.
If the thread must run all time when app is active or only when the circle rotates???
I run LunarLander sample and in this app thread running all time when app is active.
whether it is right or not?

    SurfaceView doesn’t have its own thread.It can be drawn by background threads.

    There is a distinction

    Should you Keep the thread running?

    Well it depends whether there is a point to the thread. If you need to keep it running. Obviously if you don’t need to you shouldn’t.

    If the thread has to pick up the touch events I suggest you leave it on
