i have a custom API based project... i have a php script with returns data in json form but it works well on my localhost. On godaddy it returns empty response to HttpConnection on java android. I checked it works well when i open same link on browser.
There should be a line like that in your apps manifest file. Otherwise, the app wont be able to make http requests. The fact that it loads on the browser, tells me thew API is working just fine. The only thing on the server you could configure is the headers. You can configure the CORS setting(cross orrigin requests) in the headers, you want to make sure you are allowing the requests to either come from your app, or a wildcard to allow requests from any other server/domain
