Erhalte Text von einer Webseite zu Zeichenkette

Question

Ich versuche, den ganzen Text zu einer Zeichenkette von einem HTML Dokument zu erhalten.

Hier ist mein Code

import org.apache.http.HttpResponse; 
import org.apache.http.client.methods.HttpGet; 
import org.apache.http.impl.client.DefaultHttpClient; 

import java.io.BufferedReader; 
import java.io.InputStream; 
import java.io.InputStreamReader; 

public class Admissions extends AppCompatActivity { 

TextView openclose; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_admissions); 
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); 
    setSupportActionBar(toolbar); 
    getSupportActionBar().setDisplayHomeAsUpEnabled(true); 

    //Text URL 
    DownloadWebPageTask task = new DownloadWebPageTask(); 
    task.execute(new String[]{"http://192.168.1.89/open_close.html"}); 

    openclose = (TextView) findViewById(R.id.open_close); 

} 

public class DownloadWebPageTask extends AsyncTask<String, Void, String> { 
    @Override 
    protected void onPreExecute() { 
     super.onPreExecute(); 

    } 
    @Override 
    protected String doInBackground(String... urls) { 
     String response = ""; 
     for (String url : urls) { 
      DefaultHttpClient client = new DefaultHttpClient(); 
      HttpGet httpGet = new HttpGet(url); 
      try { 
       HttpResponse execute = client.execute(httpGet); 
       InputStream content = execute.getEntity().getContent(); 

       BufferedReader buffer = new BufferedReader(
         new InputStreamReader(content)); 
       String s = ""; 
       while ((s = buffer.readLine()) != null) { 
        response += s; 
       } 

      } catch (Exception e) { 
       e.printStackTrace(); 

      } 
     } 
     return response; 
    } 

    @Override 
    protected void onPostExecute(String result) { 
     if (result != null){ 
      openclose.setText(Html.fromHtml(result)); 
     } else { 
      openclose.setText("Error"); 
     } 
     super.onPostExecute(result); 

    } 

} 

} 

Hier meine Botschaft ist, wenn 'BUILD'.

Error:Execution failed for task ':app:transformResourcesWithMergeJavaResForDebug'. 

com.android.build.api.transform.TransformException: com.android.builder.packaging.DuplicateFileException: Doppelte kopierten Dateien in APK META-INF/HINWEIS File1: M: \ AYUSH \ app \ libs \ httpcore-4.4.4.jar File2: M: \ AYUSH \ app \ libs \ Httpclient-4.5.2.jar

Vielen Dank im Voraus
