Error:Error converting bytecode to dex: Cauase: Dex cannot parse version 52 byte code. This is caused by library dependencies that have been compiled using Java 8 or above. If you are using the 'java' gradle plugin in a library submodule add targetCompatibility = '1.7' sourceCompatibility = '1.7' to that submodule's build.gradle file.

CORS is if your trying to access from one domain - another domain.

XMLHttpRequest cannot load https://www.test.com;.

 No 'Access-Control-Allow-Origin' header is present

 on the requested resource. Origin 'http://127.0.0.1:55427'

 is therefore not allowed access.

CORS is if your trying to access from one domain  - another domain.

Try withJSONP. JSONP should work , because it  uses the GET method.

Try this
var url = "https://test.com";
$http({
    method: 'JSONP',
    url: url
}).
success(function(status) {
    //success
}).
error(function(status) {
    //fails
});
