Awareness API中的TimeFence.inInterval不起作用

Question

I am using this to set up a time fence:

ArrayList<AwarenessFence> awarenessFences = new ArrayList<AwarenessFence();
awarenessFences.add(TimeFence.inInterval(timeInMillis, timeInMillis+5L));
AwarenessFence customFence = AwarenessFence.and(awarenessFences);

However, the fence is not triggered when the time falls between timeMillis and timeMillis+5L. My receivers are working properly since all other fences are working as expected. What can be the problem behind the TimeFence not working?

Answer 1

The question does not have sufficient information to pinpoint the potential issue. From testing, the specific time fence mentioned works as expected. I can make best-effort at pointing out some common issues.

• Looking at the documentation for TimeFence.inInterval , the start and stop time millis are the number of millis since epoch. Please check that the parameters being passed are actually in millis since epoch (as opposed to in a specific timezone or since start of day)

• The interval of the timeFence is 5 milliseconds which is very short. As a practical matter, I would set the interval to something that is perceivable, perhaps a few seconds or better still, one minute.

• On the earlier point, if timeMillis is obtained from System.currentTimeMillis(), then current time plus 5 ms might have already passed by the time the fence is registered with the API. Again, this points to using a longer interval in practice.
