Fixed to work on KitKat (issue #20)

 Android Webview (which Cordova is based upon) limits access to local files (such as videos) and prohibits reading them, both via relative files and `file:///` URIs. Cordova Html5Video Plugin solves this by giving each of you video a `android.resource://` path and updating your `<video>` tags accordingly.
 
 ### Limitations ###

+For Android only. Tested on Android API 15-19.
+
+For API >= 19, a workaround is employed to copy the video files over to your application's data directory, as world-readable.
+
+*WARNING*: this is potentially insecure - other apps will be able to read your videos! However it is the only way to get around Chrome's strict limitations on content:// URLs. See [Issue #20](https://github.com/jaeger25/Html5Video/issues/20) for details.
