问题 The title pretty much says it all. If you have a callback from one class to another and need to call some method from within the callback that requires a context what is the correct context to use? A common example would be an AsyncTask with a callback to the Activity or Fragment that used it.

It's using JSOUP . private long getTime() throws Exception { String url = "https://time.is/Unix_time_now"; Document doc = Jsoup.parse(new URL(url).openStream(), "UTF-8", url); String[] tags = new String[] { "div[id=time_section]", "div[id
