CordovaWebViewImpl security issue

I am new to cordova, I just created a new project for android platform using cordova 4.0, I am debugging in android studio, when I call showWebPage I got this error:

W / CordovaWebViewImpl: Blocked (possibly sub-frame) navigation to invalid URL: https: // xxxxxxxxxx

The html page lists this security config:

<meta http-equiv="Content-Security-Policy" content="default-src 'self' data: gap: https://*/* 'unsafe-inline' 'unsafe-eval'; child-src *; style-src 'self' 'unsafe-inline'; media-src *">

      

        
        
        
      

    

Can anyone please help?

thank
