I am using multi device in Delphi and I am building an android app. I need to use GetTickCount that was declared in Windows .

Does it exist somewhere in firemonkey or is there an alternative ?

This suffers from roll over due to return type being 32 bit – David Heffernan Jun 10 '16 at 17:58

This is better answer, anyway. – Free Consulting Jun 10 '16 at 19:24

Good answer, but the resolution of `GetTickCount` sucks. It is artificially limited to 1 MS resolution. [On Windows it has a drift of +/- 10 to 16](https://msdn.microsoft.com/en-us/library/windows/desktop/ms724408%28v=vs.85%29.aspx) milliseconds. Much better to use TStopWatch. And (as per david's comment) every 47.6 days your timer will roll over. – Johan Jun 10 '16 at 20:48
Bringing as portable alternative to GetTickCount is such a nonsense! – Free Consulting Jun 10 '16 at 21:30
@FreeConsulting What is so bad about TStopWatch? Is it the answer you don't approve of, or the answerer? – David Heffernan Jun 10 '16 at 21:38

Is TThread.GetTickCount any worse than the Windows API function? As far as I can see it suffers the same shortcomings but nothing worse. – dummzeuch Jun 11 '16 at 12:56
@dummzeuch not worse no, just the same pitfalls – David Heffernan Jun 11 '16 at 21:51

GetTickCount is a Windows function and so does not exist on other platforms. For your cross platform needs you should use TStopWatch from System.Diagnostics.
