example of requestSingleUpdates and looper

[Di]

Hi all,

sorry to bother. i am trying to implement one function like "one hit
to get current location, wait until i get the location, then use this
location to trigger next function", i have couple questions about,
appreciate your help:

1, is requestSingleLocation the best option for this implementation?
2, i dont quiet understand what does "Looper" mean in the method
requestSingleLocation(provider, listener, Looper), could somebody give
me a tutorial or example?

thank you

Di:

requestSingleLocation *may* be the right choice, it is had to say definitively without know more about you use case.

From my (limited) experience with requestSingleUpate(), it will only give one location update no matter how many you use with it.  The implications are that you get the first location update that Android has which is often not the most accurate location update.  If the accuracy of this update is good enough for you app, then this might work.

The looper parameter basically controls where the callback will happen from.  For the main thead, just pass null.
