Crash App - Back Button Android

[ghost]

I'm using the plugin with ionic 2,
when plugin starts and the user clicks the hardware back button, instead of "Cancel" button, the app crashes.
Did somebody had this type of problem?
Thank you.

the plugin no longer maintained ! I recently made a new plugin: https://github.com/DmcSDK/cordova-plugin-mediaPicker
