Ionic Backand App拒绝连接到Android设备上的服务器，而不是模拟器上的服务器

Question

I recently learned how to build a mobile application using Ionic and needed a backend so I decided to use the Backand framework. I am developing in Visual Studio and everything works great when run from the emulator, and all service calls work perfectly, however when I attempt to perform the same service (POST) operations from an Android Device I get the following error.

Refused to connect to 'https: //api.backand.com/1/objects/player/'; because it violates the following Content Security Policy directive: "default-src 'self' data: gap: https://ssl.gstatic.com 'unsafe-eval

I found a similar issue in which the solution was that I may need to reference the servers address in index.html 's meta tag

<meta http-equiv="Content-Security-Policy" content="default-src 'self' data: gap: https: //ssl.gstatic.com 'unsafe-inline' 'unsafe-eval'; style-src 'self' 'unsafe-inline'; media-src *; connect-src https://api.backand.com:*">

This however crashes the application and now I have hit a dead end as to where I should go from here. I would be happy to provide any more information that may be necessary, any help would be greatly appreciated!

Thanks

This is a guide on Cordova's whitelist and CSP policy: http://taco.visualstudio.com/en-us/docs/cordova-security-whitlists/ . If you have further problems with this scenario, please email vscordovatools@microsoft.com with your questions.

ensure you add cordova-whitelist-plugin after you add android platform to your application.

Order of commands have to be:

ionic platform add android

and after it

cordova plugin add cordova-plugin-inappbrowser
ionic plugin add https://github.com/apache/cordova-plugin-whitelist.git

if you change the order, ionic will install plugin only for current platform that is ios.
