KitKat changes and Import/Export in Cryptnos for Android

May 16th, 2014 | Comment?

For those who aren’t aware, Google has made a number of changes to Android in version 4.4, also known as KitKat. A full list of changes (from the developer’s perspective) can be found here. As yet, most of these don’t affect Cryptnos for Android all that much, but one change in particular is going to mean a shift in functionality.

Starting with KitKat, regular applications are no longer permitted to write just anywhere to “external storage”, which includes SD cards. While reading is still allowed with the proper permissions, apps are now restricted to writing to a single location allocated to them by the operating system. What this likely means is that the functionality we added in Version 1.1.0 of Cryptnos for Android to allow users to select the import/export location (if you have a recognized file manager app installed) is probably going to get ripped out, forcing you to save your exports to a specific folder.

Yeah, I’m not happy about that either.

I’ve created Issue #18 in the issue tracker to track this change. If you’re interested in the gory technical details, you can follow the progress there. I’m not sure how long it’s going to take me to find time to address this, but I’ll try my best to get rolling on it.

In the meantime, KitKat Cryptnos users should be able to save exports to their device’s internal storage, then manually move the file to the SD card with a file manager utility. This seems to work for me. It’s not ideal by any means, but at least it’s a functional workaround.
