WiFi overlay keeps disappearing #26

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. With a WiFi catalog selected, start logging and go to map view.
2. Zoom out 2 levels.
3. Watch the WiFi markers (both current session and from catalog).

What is the expected output? What do you see instead?
Markers are displayed as expected. However, they will frequently disappear, 
apparently in preparation for a refresh, and may take several seconds to 
reappear. Both markers for WiFis in the catalog and for current measurements 
are affected.

What version of the product are you using? On what operating system?
Revision 8e96a4f883b4, Cyanogenmod 10.1.3-RC1.

Please provide any additional information below.
A high density of WiFis in the catalog seems to aggravate the situation. I have 
parsed all of my past uploads and added the average position of each WiFi to 
the catalog, thus areas that I frequently visit have a high density of markers.
As map coverage will increase, this is likely to become a more serious issue.
This might be an upstream bug in mapsforge.

Heavily re-factored the overlay code, following the update to mapsforge-0.4.0.
Problem should be gone now, overlays in general redrawn much faster..
