Cordova Camera plugin fails
Hi everybody.
Im here with the same old mobile app. I'm trying to capture an image through camera and put it in the page, but the calls seems to fail instantly when I click the button 'Take a picture'.
If it doesn't fail, when camera is activate it shutdown the main app. I installed the https://github.com/zebra1024/cordova-plugin-wezka-nativecamera plugin which should fix that but I can't get it working.
This is index.html of my testing app
and this is the only one javascript
If someone good guy (remember we are near to Cristmas) can hlp me, I would really appreciate :)

Customize this policy to fit your own app's needs. For more guidance, see:

Some notes:
* gap: is required only on iOS (when using UIWebView) and is needed for JS->native communication
* https://ssl.gstatic.com is required only on Android and is needed for TalkBack to function properly
* Disables use of inline scripts in order to mitigate risk of XSS vulnerabilities. To change this:
* Enable inline JS: add 'unsafe-inline' to default-src
