Android OutOfMemoryError刷新数据

在我的应用程序中，我每3分钟刷新一次数据。如果应用程序将进行几个小时的工作I'go这有点错误：Android OutOfMemoryError刷新数据

java.lang.OutOfMemoryError 
at org.apache.http.util.CharArrayBuffer.<init>(CharArrayBuffer.java:55) 
at org.apache.http.util.EntityUtils.toString(EntityUtils.java:131) 
at org.apache.http.util.EntityUtils.toString(EntityUtils.java:146) 
at com.tab.Api.friends(Api.java:99) 
at com.tab.TabLayout.updateFriends(TabLayout.java:692) 
at com.tab.TabLayout.access$25(TabLayout.java:690) 
at com.tab.TabLayout$7.run(TabLayout.java:684) 
at java.lang.Thread.run(Thread.java:1102)

虽然我在此代码：“在com.tab.Api.friends（Api.java:99）”的地方是这样的：

String result = ""; 
    JSONObject jArray = null; 
    JSONArray friends = null; 

    DefaultHttpClient client = new DefaultHttpClient(); 
    try 
    { 
     HttpGet getFriends = new HttpGet("http://##########"+fb); 
     HttpResponse getResponseFriends = client.execute(getFriends); 
     HttpEntity getFriendsEntity = getResponseFriends.getEntity();      
     if (getFriendsEntity != null) 
      result= EntityUtils.toString(getFriendsEntity); 
     try 
     { 
      jArray = new JSONObject(result); 
     } 
     catch(JSONException e) 
     { 

     } 
    } 
    catch(Exception e) 
    { 
     Log.d("LOADING ERROR","Friends section"); 
    }
