Currently I’m developing a registration form for new user in Android (native app.) and by using .php file. By runnig the code I’m getting following error: “Unfortunately, application has stopped”. I tried to change code in many ways to solve it, but without any result. Here is the php code:
<?php
$dbcnx = @mysql_connect("localhost", "root", "root");
$db = "dbname";
mysql_select_db($db, $dbcnx);
$user_id=$_POST['user'];
$passwd=$_POST['passwd'];
$query = 'INSERT INTO `users` VALUES (NULL, \''.$user_id.'\', \''.$passwd.'\')';
$result = mysql_query($query) or die ("<b>Query failed:</b> " . mysql_error());
mysql_free_result($result);
mysql_close($dbcnx);
?>
And .java file:
import java.util.ArrayList;
import org.apache.http.HttpResponse;
import org.apache.http.NameValuePair;
import org.apache.http.client.HttpClient;
import org.apache.http.client.entity.UrlEncodedFormEntity;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.message.BasicNameValuePair;
import org.apache.http.protocol.HTTP;
import android.app.ListActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
public class Register extends ListActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.register);
Button Insert=(Button)findViewById(R.id.send_button);
Insert.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
try {
EditText Text1=(EditText)findViewById(R.id.user_id);
EditText Text2=(EditText)findViewById(R.id.passwd);
ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("user", ""+Text1.getText().toString()+""));
nameValuePairs.add(new BasicNameValuePair("passwd", ""+Text2.getText().toString()+""));
Log.e(""+Text1.getText().toString(),"0");
Log.e(""+Text2.getText().toString(),"0");
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://10.0.2.2/jku/user_reg.php");
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs, HTTP.UTF_8));
HttpResponse response = httpclient.execute(httppost);
}
catch(Exception e) {
Log.e("log_tag", "Error in http connection "+e.toString());
}
}
});
}
}
I fixated on my mistakes, so I’m beginner in android and any suggestions would be helpful.
I’ve checked LogCat but nothing understand. So here is the log story:

Your answer is in the error stack:
Since you didn’t show all of your code, lets assume you’re using a ListActivity or a ListFragment or whatever. To use that, the view must have a ListView child with an ID of
android.R.id.list.Read the paragraph under ‘Screen Layout’ in this d.android.com link.
