You need to find out the exact error from the android logs

You already did this workaround in step 4.

On Android you need the same files and an additional map like you have
done. But make sure that you configure the GraphHopper object in the
same way what you've generated on the desktop. Eg. if you use
chShortcuts you need to call graphhopper.setCHShortcuts(true, true)
