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？

Question

I am really confused as to why I am having this problem. I am very new to android development so I am not really sure where to start when solving this problem. I have all the required permissions in the manifest file. and .

If I use a URL like "http://www.google.com" the app works as it is supposed to work. I have tested the URL I am trying to use ( "https://api.discogs.com/users/mrblahblahblacksheep/collection/folders/0/releases?page=1&per_page=1" ) with "https://www.hurl.it/" and it works just fine. But for some reason when I try and run it with my app it crashes.

When a button is pressed myClickHandler is called and sends the url to downloadWebPageTask which starts an ASyncTask. This AsyncTank takes the URL and then sends GET request. Here is my code.

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);
        }
    }
}

Finally, here is the error message the logcat prints out when the button is pressed:

Thank you for taking a look.

Answer 1

Little late, but SSL is complex protocol with different encryption schemes, so different sites can trigger different code paths. In this case, it looks like your libcrypto was compiled for a system with more advanced capabilities than you have - maybe it wants SSE4 and your CPU doesn't have those instructions.

What CPU are you using? You'll need a fairly advanced CPU to support x86_64. Even the x86 Android ABI needs a 64 bit chip (technically it needs instructions that are only on Atom CPUs or 64 bit desktop CPUs). Try changing your Android image to plain x86.
