我正在调用网络服务在地图上绘制点。我在回复中找到了 750 条记录。当页面第二次加载时，它向我显示了这个错误。

            }

        } else {

            post = new HttpGet("my url here");

        }

        ResponseHandler<String> responseHandler = new BasicResponseHandler();

        response = client.execute(post, responseHandler);
        System.out.println("----------------------------------------");
        System.out.println(response);

        handler.sendEmptyMessage(0);
    } catch (Exception e) {
        e.printStackTrace();
        handler.sendEmptyMessage(1);
    }
}

在执行此代码期间，我也收到了 VM Out of Budget 错误。

Android Dalvik VM 有堆限制。你能告诉 Web 服务返回多少字节吗？如果数据量很大，建议增量读取数据，而不是全部传输到一个大的字符串缓冲区中。

请参考http://hc.apache.org/httpcomponents-client-ga/httpclient/apidocs/org/apache/http/client/HttpClient.html

HttpResponse response = httpclient.execute(post);
HttpEntity entity = response.getEntity();

if (entity != null) {
  InputStream instream = entity.getContent();
  try {
    BufferedReader reader = new BufferedReader(
             new InputStreamReader(instream));
    String data = null;
    while ((data = reader.readLine()) != null) {
      ...
    }
  }
}
