每次我發出一個GET語句時，應用程序都會崩潰。 我怎樣才能解決這個問題？

Question

我真的很困惑為什么我遇到這個問題。 我對android開發很新，所以我不確定在解決這個問題時從哪里開始。 我在清單文件中擁有所有必需的權限。 和。

如果我使用像"http://www.google.com"這樣的網址，該應用程序可以正常工作。 我已經測試了我嘗試使用的URL（ "https://api.discogs.com/users/mrblahblahblacksheep/collection/folders/0/releases?page=1&per_page=1" ）和"https://www.hurl.it/"它工作得很好。 但出於某種原因，當我嘗試使用我的應用程序運行它時會崩潰。

當按下按鈕時，調用myClickHandler並將url發送到downloadWebPageTask，它啟動ASyncTask。 此AsyncTank獲取URL，然后發送GET請求。 這是我的代碼。

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，這是按下按鈕時logcat打印出來的錯誤消息：

謝謝你看看。

稍晚，但SSL是具有不同加密方案的復雜協議，因此不同的站點可以觸發不同的代碼路徑。 在這種情況下，看起來您的libcrypto是為具有比您更高級功能的系統編譯的 - 也許它想要SSE4並且您的CPU沒有這些指令。

你用的CPU是什么？ 您需要一個相當高級的CPU來支持x86_64。 即使x86 Android ABI也需要一個64位芯片（從技術上講，它需要僅在Atom CPU或64位桌面CPU上的指令）。 嘗試將您的Android圖像更改為純x86。
