I tried following this tutorial: Getting Data from the Web
I tried implementing it on Android 3.0, the latest platform for tablets, however, I get this error: "Unable to resolve host "www.anddev.org" No address associated with hostname."
You can checkout the URL that I used just to prove that the file exists. http://www.anddev.org/images/tut/basic/getdatafromtheweb/loadme.txt
I created a private class and extended it with asynctask. Here is the code:
private class Downloader extends AsyncTask<String,Void,String>{
String myString = null;
@Override
protected String doInBackground(String... arg0) {
try{
URL myURL = new URL("http://www.anddev.org/images/tut/basic/getdatafromtheweb/loadme.txt");
URLConnection ucon = myURL.openConnection();
InputStream is = ucon.getInputStream();
BufferedInputStream bis = new BufferedInputStream(is);
ByteArrayBuffer baf = new ByteArrayBuffer(50);
int current = 0;
while((current=bis.read())!=-1){
baf.append((byte)current);
}
myString = new String (baf.toByteArray());
}catch(Exception e){
myString = e.getMessage();
}
return myString;
}
@Override
protected void onPostExecute(String result){
tv.setText(result);
}
}
Any help out there would be appreciated.
My bet is that you forgot to give your app the permission to use the internet. Try adding this to your android manifest:
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
