Hello,

The problem seems to be in application permissions, instead of 

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

you should have:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

Changing this made routing work in your app

By the way, the hint was in following line in Logcat.

05-23 16:28:40.288: E/graphhopper(18718): java.io.FileNotFoundException: /sdcard/mapxt/graphopper/ontario-gh/edges: open failed: EACCES (Permission denied)

Hi Jaak, i still have the same problem even after changing the app permissions. and by the way there is no where the above line that you have mentioned is shown in my logs. i am wondering, where else did you change in code, or what is the difference between my development environment and yours? thanks..

The only other place what I changed was path to the data file, to reflect gh file folder on my device.

hi Jaak, what else could be the problem, it is just not working with me!

[Jaak Laineste]

Without seeing all your logs and device contents it is quite impossible to tell. After setting permission it works fine for me.

The error message should be quite accurate, it means that map file is not opened when it is needed. You should trace application flow (with debugger and additional logging perhaps) before this error line, and check whether all operations regarding map file opening were completed successfully. If not, then check why - is working file present in expected location, is it opened successfully in read-write mode etc. Check if some other apps (graphhopper own demo app, or advancedmap3d) open same .map file and graphhopper files - if not then file contents could have problems.
