[GraphHopper] Call load error

[Daniele Germano]

Hello
 I’am try to use graphhoper but i’m stuck with this problem:

if i try to run the Sample or the apk (0.3), it crash. The crash happen when end route flag (red) is on the map. this is the Logcat:

But i see that load()  already exist in the project:

void loadGraphStorage()
    {
        logUser("loading graph (" + Constants.VERSION + ") ... ");
        new GHAsyncTask<Void, Void, Path>()
        {
            protected Path saveDoInBackground( Void... v ) throws Exception
            {
                GraphHopper tmpHopp = new GraphHopper().forMobile();
                tmpHopp.setCHShortcuts("fastest");
                tmpHopp.load(new File(mapsFolder, currentArea).getAbsolutePath());
                log("found graph " + tmpHopp.getGraph().toString() + ", nodes:" + tmpHopp.getGraph().getNodes());
                hopper = tmpHopp;
                return null;
            }

            protected void onPostExecute( Path o )
            {
                if (hasError())
                {
                    logUser("An error happend while creating graph:"
                            + getErrorMessage());
                } else
                {
                    logUser("Finished loading graph. Press long to define where to start and end the route.");
                }

                finishPrepare();
            }
        }.execute();
    }

How can i solve this problem?

Thank you
