ahoy,
in order to do offline navigation turn-by-turn (GPS) with nokia HERE Maps is there any workaround to access sd-card from android apps???
the maps will take an big amount of space and thus id like to save space using sd-card.
best regards, tobias

See [How-to] Externalising android_storage and other directories / files to SD-card for a proper solution.

Is this sufficient?
Or, create a symlink between the map folder and a SD card folder. Easy to do using Cargo Dock for example.

Try this as root
mkdir /home/nemo/sdcard
mount --bind /media/sdcard/XXXX-XXXX /home/nemo/sdcard
where XXXX-XXXX is the Id of your sd-card
Thus, the sd-card can be accessed by Android apps under /home/nemo/sdcard
You have to repeat the second step whenever you reboot the device
I recommend making this into a script and running it at startup

Note that I do not know what the long term affects of this are (I had to reset my phone due to an unrelated problem). Do this at your own risk (though realistically, nothing bad should happen...)
What I did was copy the contents of ~/android_storage to a subfolder on my sdcard called "Android".
Then I deactivated alien dalvik (not uninstall, deactivate/stop service) and renamed the android_storage folder to android_storage.old.
Finally, create a link (I think ln -s /home/nemo/android_storage /full/path/to/sdcard/Android should work) to the Android folder in the home directory and called it 'android_storage'.
Now re-enable the alien Dalvik service. With any luck your new Android SD Card is located in a folder of your real SD Card.
Note: I am typing this up from memory. If it for some reason doesn't work, deactivate the dalvik service, and rename the android_storage.old folder back to android_storage. Everything should be back the way it was after starting the alien dalvik service again...
symlinking doesn't work. it somehow still shows free space of the internal storage. Also when writing files this ends up somewhere else than the sdcard..
