Hi, the link actually returns a png file, not a webpage.
So you will have to download that file and show it in a imageview.
something like below.
import java.io.IOException;
import java.io.InputStream;
import java.net.HttpURLConnection;
import java.net.URL;
import java.net.URLConnection;
import android.app.Activity;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.os.Bundle;
import android.util.Log;
import android.widget.ImageView;
import android.widget.Toast;
public class GetImageActivity extends Activity {
/** Called when the activity is first created. */
static String res;
Bitmap bitmap;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
new Thread(new Runnable() {
public void run(){
final Bitmap bitmap = DownloadImage();
GetImageActivity.this.runOnUiThread(new Runnable() {
public void run() {
ImageView img = (ImageView)
findViewById(R.id.imageView1);
img.setImageBitmap(bitmap);
Toast.makeText(getApplicationContext(), "response
code = "+res, Toast.LENGTH_LONG).show();
}
});
}
}).start();
//
}
private static InputStream OpenHttpConnection(String urlString)
throws IOException
{
InputStream in = null;
int response = -1;
URL url = new URL(urlString);
URLConnection conn = url.openConnection();
if (!(conn instanceof
HttpURLConnection))
throw new IOException("Not an HTTP connection");
try{
HttpURLConnection httpConn = (HttpURLConnection) conn;
httpConn.setAllowUserInteraction(false);
httpConn.setInstanceFollowRedirects(true);
httpConn.setRequestMethod("GET");
httpConn.connect();
response = httpConn.getResponseCode();
if (response == HttpURLConnection.HTTP_OK) {
in = httpConn.getInputStream();
}
res = Integer.toString(response);
}
catch (Exception ex)
{
throw new IOException("Error connecting");
}
return in;
}
public static Bitmap DownloadImage()
{
Bitmap bitmap = null;
InputStream in = null;
try {
in =
OpenHttpConnection("https://chart.googleapis.com/chart?chs=250x100&chd=t:60,40&cht=p3&chl=Hello|World");
bitmap = BitmapFactory.decodeStream(in);
in.close();
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
return bitmap;
}
}
