Graphhopper - Loading routing information from a mounted obb file system error

Question

I'm trying to load the routing information from an obb file. I mounted the obb file correctly. I'm using the following code to load:

GraphHopper tmpHoppFOOT = new GraphHopper().forMobile(); 
tmpHoppFOOT.setCHShortcuts("fastest"); 
tmpHoppFOOT.setEncodingManager(new EncodingManager("FOOT")); 
tmpHoppFOOT.load(mapsFolder + currentAreaFOOT);

The load causes the following error message: AndroidRuntime(3498): Caused by: java.lang.RuntimeException: java.io.FileNotFoundException: /mnt/obb/07f4c5780b38b1ae526b333f8087a627/FootPortugal-gh/edges (Read-only file system).

I don't know what OBB is but maybe this is a problem of how the file is opened in GraphHopper. I can imagine that

raFile = new RandomAccessFile(getFullName(), "r");

instead of the current:

raFile = new RandomAccessFile(getFullName(), "rw");

should help. See MMapDataAccess line 68 and recompile. If it helps, please create a new issue on github to make this configurable in GraphHopper.
