An app to force Android to scan a storage medium for media and other files. Uses a method compatible with 4.4 KitKat and 5.0 Lollipop tested on my Nexus 5.

In Android 4.4 KitKat the method used by most older programs to rescan a storage medium no longer works. Instead an interface must be used that only allows one file to be specified at a time. This app works by determining what files/folders might need to be scanned again and then by calling the correct API on each file/folder.

This app is licensed under the GNU GPL v2 or later with source code available at http://github.com/jerickson314/sdscanner

SD Scanner can be used with Tasker by using the "Send Intent" action listed under "System."
Use the following settings leaving the ones I don't list at the default:
Action: android.intent.action.RUN
Package: com.gmail.jerickson314.sdscanner
Class: com.gmail.jerickson314.sdscanner.MainActivity
Target: Activity

If anyone wants to write a proper Tasker plugin I'll happily take a Pull Request on Github.
