Which is Android/Java corresponding method to the C#/C++ method GetTickCount()?

Question

I wanna know a corresponding method in Android/Java that is like the GetTickCount method in C#/C++?

Answer 1

For Android it is SystemClock.uptimeMillis(). Please note that uptimeMillis() does not include time spent in deep sleep. You may need SystemClock.elapsedRealtime() for total time after boot.
