API响应JSON等待最终结果

Question

I'm new here and new to JavaScript programming in Android Studio too. I'm working on a app that uses the API called page2images that gives back the screenshot of a website by searching a URL. The response is a JSON code, but when I make a call I see something like this:

{"status":"processing","estimated_need_time":50}

after a while it shows me this:

{"status":"finished","image_url":"http://api.page2images.com/ccimages/fd/fb/jDgCCNYu2kyKwKDs.png","duration":1,"left_calls":"2910","mobileok":"yes","ori_url":"http:\/\/www.twitter.com"}

that's what I need.. but how can I make the program wait till the second code is showed? the URL is the same and if I refresh the page I can see the estimated_need_time decreasing but if I do the parsing of image_url I would have to wait the right response but when I click the button the app would have to do all by its own..

Answer 1

I'm not sure I correctly see your problem, but If I do just wait "estimated_need_time" and call the api again. Parse the first answer, set for example a handler to wait responded amount of seconds and call the api again. It should solve your problem.
