Please i am trying to fetch json data to populate into ListView from a server and am getting a null value.
Plz what can be wrong as this is my first project on android.
public void getdata(){
ListView listview=(ListView) findViewById(R.id.listview);
String result="";
try{
Url url=new Url("http://www.url.com/forum.php");
URLConnection conn=url.openConnection();
conn.setDoOutput(true);
BufferedReader rd=new BufferedReader(new InputStreamReader(conn.getInputStream()));
String line;
StringBuilder sb=new StringBuilder();
while((line=rd.readLine())!=null){
sb.append(line+"\n";
}
rd.close();
result=sb.toString();
} catch(Exception e){
showAlart(e.getMessage());
}
}
try{
List<String>array=new ArrayList<String>();
String title="";
JSONArray jArray=new JSONArray(result);
for(int i=0; i<jArray.length(); i++){
JSONObject json=jArray.getJSONObject(i);
title=title+"title: "+json.getString("title"+"\n";
array.add(title);
}
ArrayAdapter<String> adapter=new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, array);
listview.setAdapter(adapter);
} catch (Exception e){

}
}

The last time I did Android was 2013

Looking at your code, everything seem right.

Check the URL you are parsing to see the kind of JSON response you are getting or if it is returning JSON at all.

D server side is ohk.
I just need sumbdy who has done sumtin lyk diz b4 to look into it

Change
Url url=new Url(" http://www.url.com/
forum.php" );
to

final String URL = "http://www.url.com" ;

Just try that

Paste your JSONArray here let's see.

Ohk
