How to let Android apps to write to (real) sdcard
I have an ext4 formatted (class 10) sdcard, which auto-mounts correctly, thanks to
https://github.com/nemomobile/sd-utils/pull/8/files
Out of the box, Android apps can write to a special directory /data/sdcard, which is not really the sdcard, but just a special directory on phone memory.
My problem is that I'd like to use offline maps with OsmAnd+ for Android, and would prefer those maps to be saved on the real sdcard to avoid running out of memory for camera photos etc too soon.
Simply symlinking a directory from the sdcard as /data/sdcard didn't seem to work (even with chmod a+rwx).
