这是我在asyncTask中运行此方法时遇到的错误。

public void getImages() throws IOException{


    DefaultHttpClient httpclient = new DefaultHttpClient();

    HttpGet httppost = new HttpGet("https://sites.google.com/site/theitrangers/images/webImages.txt");
    HttpResponse response;

        response = httpclient.execute(httppost);


            HttpEntity ht = response.getEntity();

            BufferedHttpEntity buf = new BufferedHttpEntity(ht);

            InputStream is = buf.getContent();


            BufferedReader r = new BufferedReader(new InputStreamReader(is));

            StringBuilder total = new StringBuilder();
            String line;
            while ((line = r.readLine()) != null) {
                total.append(line + "\n");


              Log.v("getImage1", "Retreived image");
            }
            imageUrl = total.toString();
     }

代码中的网址（https://sites.google.com/site/theitrangers/images/webImages.txt）解析为61字节字符串https://sites.google.com/site/theitrangers/images/ncaa12.jpg。所以这可能不是你堆上的主要消耗。有可能你有很多其他东西耗尽了你的记忆，这恰好是事情的结果。无论如何，当您分配BufferedReader时，OOM看起来就像是在发生。缓冲区的大小实际上大于内容的大小（前面提到的61字节字符串）。您可以在BufferedReader's constructor中指定较小的缓冲区。无论如何，你真的不需要一个61字节实体的缓冲区。同样，您可能不需要使用BufferedHttpEntity。你可以更进一步减少这里使用的内存，但你的应用程序中还有其他东西占用了更多的内存。

字节分配时出现内存不足错误？
