无法从字符串创建JSON对象

Question

所以我试图从这个字符串创建一个JSON对象，因为我将访问iTunes查找api，但我似乎无法创建JSONObject。我已经看过每一个基于android/java的解决方案，我似乎无法得到它的工作。谢谢！

import org.json.JSONException; 
import org.json.JSONObject; 

public class api_caller { 

static String api_out = "{\"wrapperType\":\"track\", \"kind\":\"podcast\", \"collectionId\":274450056, \"trackId\":274450056, \"artistName\":\"Giant Bomb\"}"; 

static String fin = api_out.replace("\\", ""); 

public static void main(String[] args) { 
    System.out.println(fin); 
    try { 
     JSONObject jsondata = new JSONObject(fin); 
    }catch(JSONException e){ 
     e.printStackTrace(); 
    } 
} 

} 

编辑：

所以我试了一下达山提及。但是我一直在得到这个错误。

有没有必要的string.replace()操作，报价已经逃脱。以下应该工作正常：

System.out.println(api_out); 
try { 
    JSONObject jsondata = new JSONObject(api_out); 
    System.out.println(jsondata); 
} catch (JSONException e) { 
    e.printStackTrace(); 
}
