Date: 2017jan18 OS: Android Keywords: example Q. How can I use sendMessageAtTime() with epoch time? A. sendMessageAtTime() expects uptimeMillis so you need to convert your time.

boolean sendMessageAtEpochTime(Handler handler, final Message msg, final long epochTime) { final long diff = epochTime - System.currentTimeMillis(); final long when = SystemClock.uptimeMillis() + diff; return handler.sendMessageAtTime(msg, when); }

You can also use

return handler.sendMessageDelayed();

But I see in the Android source that it just calls sendMessageAtTime();
