Developer Features: Preferences
Caution: use this feature only, if you exactly know what you do!
There is an option to set manually shared preferences values. Create in the config folder a subfolder load containing any file with the extension
“.properties” which contain key value pairs. By default these preferences are considered as String preferences. Using the prefix “Boolean:” in the
value is changing this behaviour to a Boolean preference.
Location based search
If you use the playstore version and you want to use full search functionality, you need to set
FSSearch.reverseSearchOn=Boolean:true
FSSearch.locationBasedSearchOn=Boolean:true
From the device you can use this link create this configuration: geocode.zip
Routing algorithm
You can configure three different routing algorithms:
- AStar
- BidirectionalAStar (AStar with search in both directions, delivers optimal result)
- BidirectionalAStarFNO (AStar with search in both directions, faster, but may deliver none optimal result)
For BidirectionalAStar it looks like this:
#FSRouting.RoutingAlgorithm=AStar
FSRouting.RoutingAlgorithm=BidirectionalAStar
#FSRouting.RoutingAlgorithm=BidirectionalAStarFNO
Direct Map Download
The download of mapsforge vector maps is done via the openandromaps site. Since this page was recently down and because the location of the maps is in fact an ftp server:
https://ftp.gwdg.de/pub/misc/openstreetmap
there is an option download directly from the ftp server. For this purpose you can use the preference:
DownloadMapsDirect=Boolean:true
Load tiles for transparent layers
When you use tile stores and also the hgt layer, then you can use the bounding box to load further tiles/hgt files. If there is more than one layer that mght be the target of such an operation, you will get a dialog to select the layer on which the operation (load remaining, load all or delete all) shall be executed. The standard behaviour is to offer all Tilestore and HgtGridLayers, except these layers are fully transparent at that point of time. With the property
FSBB.loadTransparent=Boolean:true
you will get also transparent layers offered for the operation.
Mapsforget Number of Render Threads
This property allows to manipulate the number of render threads in mapsforge.
prefMapsforgeNumRenderThreads=4
Sample config
The following sample configuration
#FSRouting.RoutingAlgorithm=BidirectionalAStarFNO
FSRouting.RoutingAlgorithm=BidirectionalAStar
FSSearch.reverseSearchOn=Boolean:true
FSSearch.locationBasedSearchOn=Boolean:true
DownloadMapsDirect=Boolean:false
#FSBB.loadTransparent=Boolean:false
#prefMapsforgeNumRenderThreads=4
#trackGpxDir=/storage/180F-2D14/Android/data/mg.mgmap/files/gpx
can be downloaded and installed here. After installation you can use the internal FileManager to modify these preferences.
