Graphhopper crash in nutiteq

[don...@upande.com]

hi i am trying to use graphhopper with nutiteq sdk for offline routing but the app crashes both on emulator and device. i am seeing this error - 05-22 03:52:17.557: E/AndroidRuntime(700): Caused by: java.lang.IllegalStateException: no map file is currently opened

05-22 03:52:17.557: E/AndroidRuntime(700): at org.mapsforge.map.reader.MapDatabase.getMapFileInfo(MapDatabase.java:238)

To give any useful help I’d need full stacktrace, your code sample and your data file package.

Did you try same data package - was it working with AdvancedMap3D sample app? If it worked there, then the problem is probably like error tells: make sure you have opened the .map file before you call getMapFileInfo()

Hello,

Do you have file open success in your log? Your code logs it, but your log extract does not have it. Sounds like file not found.

Message should be "MapsforgeRasterDataSource: MapDatabase opened ok"

 hi Jaak, it might be that the file is not being found, but what do you think is causing this yet the file is available and i have set the path correctly. thanks..
