java - 每次我执行某个 GET 语句时，应用程序都会崩溃。我怎样才能解决这个问题？

Question

我真的很困惑为什么我会遇到这个问题。我是 android 开发的新手，所以我不确定在解决这个问题时从哪里开始。我在 list 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 URL，该应用程序将按预期运行。我已经测试了我尝试使用的 URL ("https://api.discogs.com/users/mrblahblahblacksheep/collection/folders/0/releases?page=1&per_page=1") "https://www.hurl.it/" 并且它工作得很好。但出于某种原因，当我尝试使用我的应用程序运行它时，它崩溃了。

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 打印出的错误消息:

感谢您的关注。

有点晚了，但 SSL 是一种复杂的协议(protocol)，具有不同的加密方案，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 是为具有比您拥有的更高级功能的系统编译的 - 也许它需要 SSE4 而您的 CPU 没有这些指令。

你用的是什么CPU？你需要一个相当高级的 CPU 来支持 x86_64。甚至 x86 Android ABI 也需要 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 镜像更改为纯 x86。
