每次我发出一个GET语句时，应用程序都会崩溃。我怎样才能解决这个问题？

我真的很困惑为什么我遇到这个问题。我对android开发很新，所以我不确定在解决这个问题时从哪里开始。我在清单文件中拥有所有必需的权限。和。

如果我使用像"http://www.google.com"这样的网址，则应用可以正常工作。我已经使用"https://api.discogs.com/users/mrblahblahblacksheep/collection/folders/0/releases?page=1&per_page=1"测试了我尝试使用的网址（"https://www.hurl.it/"），它运行正常。但出于某种原因，当我尝试使用我的应用程序运行它时会崩溃。

当按下按钮时，调用myClickHandler并将url发送到downloadWebPageTask，后者启动ASyncTask。此AsyncTank获取URL，然后发送GET请求。这是我的代码。

public void myClickHandler(View view) {
    SetText url = new SetText();
    //String string_url = url.createURL(artist_text.getText().toString(), release_text.getText().toString());
    new DownloadWebpageTask().execute("https://api.discogs.com/users/mrblahblahblacksheep/collection/folders/0/releases?page=1&per_page=1");
}

public class DownloadWebpageTask extends AsyncTask<String, Void, String> {
    @Override
    protected String doInBackground(String... urls) {

        String url = urls[0];
        String final_response = "FAILED!";

        HttpClient client = new DefaultHttpClient();
        HttpGet request = new HttpGet(url);

        HttpResponse response;
        try {
            response = client.execute(request);

            final_response = EntityUtils.toString(response.getEntity());
        } catch (ClientProtocolException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }

        return final_response;
    }
    // onPostExecute displays the results of the AsyncTask.
    @Override
    protected void onPostExecute(String result) {
        if(result == null) {
            result_text.setText("Try Again");
        } else {
            result_text.setText(result);
        }
    }
}

最后，这是按下按钮时logcat打印出来的错误消息：

稍晚，但SSL是具有不同加密方案的复杂协议，因此不同的站点可以触发不同的代码路径。在这种情况下，看起来您的libcrypto是为具有比您更高级功能的系统编译的 - 也许它想要SSE4并且您的CPU没有这些指令。

你在用什么CPU？您需要一个相当高级的CPU来支持x86_64。即使x86 Android ABI也需要一个64位芯片（从技术上讲，它需要仅在Atom CPU或64位桌面CPU上的指令）。尝试将您的Android图像更改为普通x86。
