In my app I try to put n objects on to the screen.
They need to be placed according to their latitude, longtitude etc. And when ı move my telephone around(not touching)
ı should be seeing them flawing around, according to their coordinates.
There are two questions.
Is there a method that takes lat, long and convert them to screen coordinates?
And how can ı set the place of object to a coordinate and when ı move the camera to left, object should dissaapear.
When ı turn right it should come again.

I feel like couldnt explained myself, but if you know metaio AR framework ı am trying to create its functionality, its third tutorial GPSLocationBasedActivity.
I hope you try what ı tried to mean.

Thanks in advancé!
