更新：我获取数据和存储的方法：

JSONParser jParser = new JSONParser();
JSONObject json = jParser.getJSONFromUrl(url);
// TODO Auto-generated method stub

JSONArray Erate= json.getJSONArray("Erates");

if (Erate != null)
{
    // looping through All Contacts
    for(int i = 0; i < Erate.length(); i++)
    {
        JSONObject c = Erate.getJSONObject(i);
        Cursor cr = db.rawQuery("select * from `rates` where `id`='"+c.getString("id")+"'",null);

        String query = "Insert into rates(id, kondisi, condition, tenor, erate, erateDB)"+
                       "values("+
                            c.getString("id")+",'"+
                            c.getString("....")
                            +"')";

        db.execSQL(query);
        Log.d("Insert", query);

        cr.close();}
    }

有什么建议如何让它发挥作用吗？

我认为从 JSON 响应中生成子字符串的逻辑url并获得有效的 JSON 响应

代码如下：

int start = url.indexOf("{");   // index from where valid json starts
int end = url.lastIndexOf("}"); // index where valid json completes

// get valid json string by substring method
String validJson = url.substring( start, end+1);
