Not directly, but you could use computed attributes to convert it to some attribute that you can use for filtering, like validity flag or accuracy.
Ok! Thanks! I make computed attibute and receive true or false. Then how can I use this attribute in filter?
That's why I said you need to use something that has filtering. You can't filter by an arbitrary attribute.
Ok. I used attribute "Accuracy" for this purpose. When activity equal still then accuracy set to 1000 it is more that in configuration
<entry key='filter.accuracy'>50</entry>
but it not filtered, it show with accuracy 1000

What priority did you set? You need to set a negative value.
Perfect!!! All Works!!! Thanks!!! Need set negative priority!!!
Just another question, it is possible to get data from previous valid location in computed attributes?
Why not? It should be possible.
Can you take example? For example I need previous battery level what operator should I use?
You can use lastBatteryLevel. Make sure you enable it in the config though.
Thanks Very Mach!!! Where I can find full list of attibutes for using in Expression?
Oh!!! Sorry!!! All found!!! Thanks!!!
Hi all!
I use android client on few devices, and I found attribute "activity" in log. It is possible to filter receiving position by activity = still?
May be it can make from computed attributes?
