我不明白为什么会出错，这个应用程序不会经常崩溃，只有几次。当我离开应用程序一段时间时会发生这种情况。代码出错的地方：

public static String doGetRequest(String url) throws IOException{
        HttpClient lClient = new DefaultHttpClient();
        HttpGet lGetMethod = new HttpGet(url);

        HttpResponse lResp = null;
        try {
            lResp = lClient.execute(lGetMethod);
        } catch (ClientProtocolException e1) {
            Log.v(TAG, e1.toString());
            e1.printStackTrace();
        } catch (IOException e1) {
            e1.printStackTrace();
        }

        ByteArrayOutputStream lBOS = new ByteArrayOutputStream();
        String lInfoStr = "";

        if (lResp != null){
            try {
                lResp.getEntity().writeTo(lBOS);
                lInfoStr = lBOS.toString("UTF-8");
            } catch (IllegalStateException e) {
                e.printStackTrace();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
        return lInfoStr;
    }

lInfoStr = lBOS.toString("UTF-8");这条特殊线

我该如何解决这个问题？ toString()会花费大量内存吗？

outofmemoryerror toString（“UTF-8”）ByteArrayOutputStream在android中
