Android：跳过417帧。尝试从数据库加载图像时来自Choreographer的消息

Question

我正在使用服务从数据库中检索数据。在DB中，我以字节的形式存储了图像，因为来自请求的响应是巨大的。无论如何，当我尝试获取值时，我得到一个错误，说417帧跳过，应用程序做了太多的工作。我在AsyncTask上运行整个请求，所以它在后台执行。我不知道为什么会发生错误。

该片段如下： -

    private class NetworkCall  extends AsyncTask<Void, Void, CharSequence>{

    @Override
    protected CharSequence doInBackground(Void... params) {
        CharSequence seqResult = null;

        try{

            //http post request

            HttpPost post = new HttpPost("http://localhost/HookService/SvcFiles/Hook.svc/GetAllUsers");
            post.setHeader("Accept", "application/json");
            post.setHeader("Content-type", "application/json");

            int p_iRadius = 20;

            JSONStringer postParameters = new JSONStringer()
            .object()
                .key("p_iRadius").value(p_iRadius)
            .endObject();

            post.setEntity(new StringEntity(postParameters.toString()));   

            //get the response
            HttpResponse response = client.execute(post);

            // stream reader object
            Reader resultReader = new InputStreamReader(response.getEntity().getContent());
            //create a buffer to fill if from reader
            char[] buffer = new char[(int) response.getEntity().getContentLength()];
            //fill the buffer by the help of reader
            resultReader.read(buffer);
            //close the reader streams
            resultReader.close();
            seqResult = java.nio.CharBuffer.wrap(buffer);
        }
        catch (Exception e) {
            Log.e("Web Service Error", "Web Service error", e);
        }

        return seqResult;
        }
        @Override
        protected void onPostExecute(CharSequence Result){      
            JSONArray resultArray = null;

            try{
            JSONObject jsonObject = new JSONObject(Result.toString());
            resultArray  = jsonObject.getJSONArray("ReturnModel");
                //resultArray = new JSONArray(Result.toString());
            }catch(Exception e){
                Log.e("Json error", "Json error", e);
            }

            GsonBuilder gsonb = new GsonBuilder();
            DateDeserializer ds = new DateDeserializer();
            gsonb.registerTypeAdapter(Date.class, ds);
            Gson gson = gsonb.create();
            Type datasetListType = new TypeToken<Collection<MapPushPinData>>() {}.getType();

            try{
            mapUserList = gson.fromJson(resultArray.toString(), datasetListType);
            }
            catch (Exception e){
                Log.e("Serialization Error", "Error", e);
            }

            setUpMapIfNeeded();
        }
}

基本上我获取凭据在地图上用小图像和名称绘制标记。当请求发出时，跳过帧，因为没有绘制标记。

此外，我在模拟器上运行它，我无法在设备上测试它，因为我的设备无法包含在同一网络中。
