Yay, first bug report!

Thanks for the stack trace. It looks like external storage couldn't be mounted for some reason. The problem is most likely due to your device, not the app itself (but I should add an error screen to handle it).

If you set the logcat log level to "info", you should see a line with the tag "Tour", that says something like "unknown", "removed", "unmounted", "bad_removal", et cetera, which will give an idea of what's wrong.

Hey WOA,

Thanks for the quick reply. it says:

10-05 19:19:49.391    6188-6188/? I/Tour﹕ mounted
10-05 19:19:49.391    6188-6188/? W/ContextImpl﹕ Failed to ensure directory: /storage/emulated/0/Android/data/alicrow.opencvtour/files

Can you share alicrow.opencvtour/files folder so that i can manually add it to my phone and test it?

Fixed it:

public static File getToursDirectory(Context context) {
        Log.i(TAG, Environment.getExternalStorageState());

        if(_tours_directory == null)
            _tours_directory = Environment.getExternalStorageDirectory();

        return _tours_directory;
    }
