Cordova fileOpener2 activity not found on android

I use IonicFramework for my mobile app, and I have a problem:

1. I download a file to the app's directory (/data/data/[PACKAGE]/).
2. I check if the file was downloaded (with the Android File Finder). It was.
3. I open up the file with the plugin fileOpener2 and expect a dialog to be opened (with different native programs that can open up the file).

Actual result: http://cubeupload.com/im/frfONC.jpg
