Folks,
Overlay construction happens at each boot of the app - what is happening is that the system opens the
places database, read all records and adds them to the map. This is about 90,000 records and this can take some time, it is all dependant on the CPU speed and available memory of your device. So may take a little longer than others. I have been trying to work out a faster way however the data is large and takes some time to read no matter how I store it.
Happening for a longer time may happen just after an update of the
places data as it also can take a long time to write the
places to the database after the update has occurred. The subsequent read to build the overlay data on the map cannot complete till the whole write process has completed - I have seen this take several minutes on some devices.
Hope this helps.
