I have been trying many of the codes that have been posted on stackoverflow itself. However, none have worked for me so far. I'm new to android and there's probably something I'm overlooking. Kindly help fix this code - 

```
package com.alphageeks.pespitstop;

import java.io.InputStream;
import java.net.URL;

import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.entity.BufferedHttpEntity;
import org.apache.http.impl.client.DefaultHttpClient;

import android.app.Activity;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.Toast;

public class Vop extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_vop);

    Button bnot = (Button) findViewById(R.id.bnot);
    Button bcant = (Button) findViewById(R.id.bcant);
    Button bcal = (Button) findViewById(R.id.bcal);
    final ImageView img = (ImageView) findViewById(R.id.imageView1);
    final Toast disp = null;

    bnot.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            try {
                URL url = new URL("https://drive.google.com/file/d/0B-bEff6i-vWoUHpWS3h1VUR4ZkE/edit?usp=sharing");
                //try this url = "http://0.tqn.com/d/webclipart/1/0/5/l/4/floral-icon-5.jpg"
                HttpGet httpRequest = null;

                httpRequest = new HttpGet(url.toURI());

                HttpClient httpclient = new DefaultHttpClient();
                HttpResponse response = (HttpResponse) httpclient
                        .execute(httpRequest);

                HttpEntity entity = response.getEntity();
                BufferedHttpEntity b_entity = new BufferedHttpEntity(entity);
                InputStream input = b_entity.getContent();

                Bitmap bitmap = BitmapFactory.decodeStream(input);

                img.setImageBitmap(bitmap);

            } catch (Exception ex) {
                    disp.makeText(Vop.this, "error",Toast.LENGTH_SHORT).show();
            }

        }
    });

}

```
