Error parsing XML via HTTP
In this given code, my HTTP-related code is working correctly and it is giving correct result in toast message. However when I apply parsing of the HTTP content (XML), it will force close.
What is the exact problem with what I'm doing here?
public class Player extends Activity {
String d="";
TextView id[];
TextView name[];
String str;
TableLayout t1;
private HttpEntity responseEntity;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.player);
TableLayout t1 = (TableLayout) findViewById(R.id.myTable);
Intent i = getIntent();
Bundle b = i.getExtras();
String str = b.getString("ARRIVING_FROM");
TextView title = (TextView) findViewById(R.id.TextView01);
title.setText(str);
d=d+"";
d = tryLogin(str);
System.out.println("Value of D"+d.substring(0, 1));
if(d.substring(0, 1).equalsIgnoreCase("1"))
//if(d.equals(str))
{
Toast.makeText(getApplicationContext(), "OOPS", Toast.LENGTH_SHORT).show();
}
else
Toast.makeText(getApplicationContext(), d, Toast.LENGTH_SHORT).show();

xr.parse(retrieveInputStream(responseEntity));
} catch (Exception e) {
System.out.println("XML Parsing Excpetion = " + e);
}
final ScoreList scorelist = XMLHandler.scorelist ;

You have a NullPointerException
on line 91 of MyPlayerInfo
, in the onCreate()
method.
Also, never do network I/O and parsing on the main application thread. Use an AsyncTask
or some other form of background thread, please.
