[android-beginners] [Help] About URLConnection
Hi,
I don't know why it doesn't work,
I'm using eclipse version 3.4
and android sdk0.9beta
Actually, I want to get the html code from a website,
and it throw to EXCEPETION , unknown error.
Then I try a sample code from http://www.anddev.org/working_with_files-t115.html
I found that when it runs .getInputStream(), it throw throw to
excepetion.
Here is the code.
-
package com.demo.test;
import java.net.*;
import java.io.*;
import org.apache.http.util.ByteArrayBuffer;
import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
public class test extends Activity {
@Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
/* We will show the data we read in a TextView. */
TextView tv = new TextView(this);
/* Will be filled and displayed later. */
String myString = null;
try {
/* Define the URL we want to load data from. */
URL myURL = new URL(
http://www.anddev.org/images/tut/basic/
getdatafromtheweb/loadme.txt);
/* Open a connection to that URL. */
myString = before inputStream2;
URLConnection ucon = myURL.openConnection();
/* Define InputStreams to read
* from the URLConnection. */
InputStream is = ucon.getInputStream();
BufferedInputStream bis = new BufferedInputStream(is);
/* Read bytes to the Buffer until
* there is nothing more to read(-1). */
ByteArrayBuffer baf = new ByteArrayBuffer(50);
int current = 0;
while((current = bis.read()) != -1){
baf.append((byte)current);
}
/* Convert the Bytes read to a String. */
myString = new String(baf.toByteArray());
} catch (Exception e) {
/* On any Error we want to display it. */
//myString = e.getMessage();
}
/* Show the String on the GUI. */
tv.setText(myString);
this.setContentView(tv);
}
}
