解决方案
您正在运行里面的onCreate 2 asynctasks（）方法。由于这些都是异步的GetXMLTask是为空字符串与执行CoverImage。
所以，这个移动code：
GetXMLTask任务=新GetXMLTask（）;
task.execute（Coverimage）;
到 onPostExecute（）您的详细方法的AsyncTask会解决这个问题。
i am parsing a json string from which i get the url of image. then i pass that url to a method to get the image and display it in an imageview but the image does not loaded and throws an exception of java.net.MalformedURLException. when i try to pass the image url directly to the method then it gets loaded. so i dont know where is the error. Any help will be appreciated. thanks in advance. my code is below

解决方案
You are running two asynctasks inside onCreate() method .As these are asynchronous your GetXMLTask was executed with String CoverImage as null . So , moving this code :
GetXMLTask task = new GetXMLTask();
task.execute(Coverimage);
to the onPostExecute() Method of your Details asynctask will solve the problem .
