Apps Can't append text in new Intent

[zuhra0105]

Hi,
I am working on a student project and i have to make an android based application that will connect on a server having mysql databse(using servlets), and this server has automatic response on every update of database. I made standalone non android application in java and it works fine. When i use this code, adapted for android, to run on android emulator i can't see these results on new intent layout. I am using 2 intents, the first, starting intent, executes mysql query and it calls second intent that has a simple EditText compomnent and I want to see results in that second component. The problem is when second intent is started there is only black screen.

Here is the code of the first Intent:

Java:
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.*;
import android.content.Intent; // postavljanje Intenta
import android.net.Uri; // parsiranje URI-a




public class projekt extends Activity implements OnClickListener {


private CheckBox prvi;
private CheckBox drugi;
private Button gumb;
static public String url;


public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

prvi = (CheckBox) findViewById(R.id.prvi);
drugi = (CheckBox) findViewById(R.id.drugi);
gumb = (Button) findViewById(R.id.gumb);
gumb.setOnClickListener(this);


}

public void onClick(View v) {
if(v == gumb) {
url = upit(prvi,drugi);

Intent prozor = new Intent (this,prozor.class);

prozor.setFlags(Intent.FLAG_ACTIVITY_BROUGHT_TO_FRONT);
prozor.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);


startActivity(prozor); }

}

public String upit (CheckBox prvi, CheckBox drugi) {

if(prvi.isChecked() && drugi.isChecked()) {

return "select%*%from%tablica" ;

} else if (prvi.isChecked()) return "select%ime%from%tablica";

else if(drugi.isChecked()) return "select%prezime%from%tablica";
else return "ERROR!!";



}
}


Here is the code of second intent:

Java:

import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.FileWriter;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.MalformedURLException;
import java.net.URL;
import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.os.PowerManager;
import android.os.PowerManager.WakeLock;
import android.widget.*;
import java.io.*;
import org.xml.sax.SAXException;
import org.xml.sax.XMLReader;
import java.io.FileOutputStream;
import java.iutputStreamWriter;
import javax.xml.parsers.SAXParser;
import javax.xml.parsers.SAXParserFactory;


public class prozor extends Activity {


private int id=0;
private EditText prikaz;
private FileOutputStream fOut = null;
private String path_local = "/data/data/projekt.android/files/bogovski.xml";
String adresa = projekt.url;

public static StringBuffer parsbuf = new StringBuffer();;




public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

setContentView(R.layout.prozor);


prikaz = (EditText) findViewById(R.id.tekst);
prikaz.append("...."); //-----------------------------------------------------------------TESTING SECOND INTENT
prvakonekcija(adresa,id);


}











public void prvakonekcija(String address,int id) {

URL page;
String line;
StringBuffer text = new StringBuffer();

try {

page = new URL("SERVER_URL_GOES_HERE"+projekt.url);

try {
HttpURLConnection konekcija1 = (HttpURLConnection) page.openConnection();
konekcija1.connect();



BufferedReader in1 = new BufferedReader(
new InputStreamReader(
konekcija1.getInputStream()));


do {

line = in1.readLine();
if(line == null) break;
text.append(line + "\n");
} while (line != null);


try {

BufferedWriter out = new BufferedWriter(new FileWriter(path_local));
out.write(text.toString());
out.close();


} catch (IOException e) {
System.out.println(e.getMessage());
}



SAXParserFactory spf = SAXParserFactory.newInstance();
SAXParser sp = spf.newSAXParser();
XMLReader xr = sp.getXMLReader();
Parser handler = new Parser(id);
xr.setContentHandler(handler);
xr.setErrorHandler(handler);
sp.parse(new File(path_local), handler);

System.out.println(parsbuf.toString());
prikaz.append(parsbuf.toString());


URL page1 = new URL("SERVER_URL_GOES_HERE");
HttpURLConnection konekcija2 = (HttpURLConnection) page1.openConnection();
konekcija2.connect();


BufferedReader in2 = new BufferedReader(
new InputStreamReader(
konekcija2.getInputStream()));


do {
line = in2.readLine();
} while (line == null);


konekcija2.disconnect();
konekcija1.disconnect();
int salji = Integer.parseInt(line);
prvakonekcija(adresa,salji);


} catch (IOException ioe) {
System.out.println(ioe.getMessage());

} catch (SAXException e) {
System.out.println(e.getMessage());

} catch (Exception e) {
System.out.println(e.getMessage());
}

} catch (MalformedURLException e) {
System.out.println(e.getMessage());
}

}
}



I have a parser class that parses the xml and second intent is using this class i have added to my project. The code that is commented as "testing second intent" in onCreate method of second intent is shown only when i comment out the next line of code (calling of function prvakonekcija(adresa,id). It is interesting that application works with System.out.println and results can be seen in Logcat, but when i try to append it on EditText component nothing is happening (only black screen). I've uploaded screen shot of snippet of logcat log here: http://img689.imageshack.us/img689/2677/logcat127.jpg .

In red circle you can see correct application results that I want to see on second Intent. Maybe the line in blue square (in Logcat) is causing problems?!?

Thank you in advance for your time
