Post image to Facebook in JSON format in Android_问答_开发者

I want to post image to the Facebook in which I am having my JSON string,I have included static image in the string, and it works fine, if I want to add dynamic image wh开发者_如何学JAVAat can I do for if?

Here is my code:

 parameters.putString(
    "attachment",
  "{\"name\":\""
  + b.getString("title")
  + "\",\"href\":\""
  + b.getString("cmpWeb")
  + "\",\"description\":\""
  + desc
 + "\",\"media\":[{\"type\":\"image\",\"src\":\"http://184.106.227.45/quaddeals/img/small_thumb/Deal/692.e6b86fa39f3ba25e29f0351140b57a94.jpg\",\"href\":\"http://alumni.brown.edu/\"}]}");

This value is http://184.106.227.45/quaddeals/img/small_thumb/Deal/692.e6b86fa39f3ba25e29f0351140b57a94.jpg\" static value I want to include dynamic content that I got from previous page by using intent,say(b.getString("url")).

Also I want to show the web link if user click the link it should shows the Web View is also static "http://alumni.brown.edu" i want to include dynamic data.
