i'm trying make change app, fail, database.xml in assets..the app display xml, xml file exist in assets. how can file url?

mainactivity.java:

package com.hixa.streattraffic; import java.io.ioexception; import java.util.list; import android.app.activity; import android.os.bundle; import android.widget.arrayadapter; import android.widget.listview; public class mainactivity extends activity {     listview listview;      @override     protected void oncreate(bundle savedinstancestate)     {         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_main);         listview = (listview) findviewbyid(r.id.list);         list<street> streets = null;         try         {             parserhandler parser = new parserhandler();             streets = parser.parse(getassets().open("database.xml"));             arrayadapter<street> adapter = new arrayadapter<street>(this,     r.layout.list_item, streets);             listview.setadapter(adapter);         }         catch (ioexception e)         {             e.printstacktrace();         }     } } 

parserhandler.java

street.java:

package com.hixa.streattraffic;  public class street {     //private int id;     private string street_name;     private string intersection_no;     private string traffic_state;     private string time;      public street(){}      /*public street(int id)     {         this.id = id;     }*/          public street(string street_name, string intersection_no, string traffic_state, string time)     {         //this.id = id;         this.street_name = street_name;         this.intersection_no = intersection_no;         this.traffic_state = traffic_state;         this.time = time;     }      public string getstreet_name()     {         return this.street_name;     }      public void setstreet_name(string street_name)     {         this.street_name = street_name;     }      public string getintersection_no()     {         return this.intersection_no;     }      public void setintersection_no(string intersection_no)     {         this.intersection_no = intersection_no;     }      public string gettraffic_state()     {         return this.traffic_state;     }      public void settraffic_state(string traffic_state)     {         this.traffic_state = traffic_state;     }      public string gettime()     {         return this.time;     }      public void settime(string time)     {         this.time = time;     }      @override     public string tostring()     {         return "time : " + time + "\nstreet name : " + street_name +"\nstreat     intersection no. : " + intersection_no+ "\nstreat traffic state : " + traffic_state;     } } 

my question (hope can help) in mainactivity.java there function

streets = parser.parse(getassets().open("database.xml")); 

i want same xml file server, how can achieve this?

thanks

try this

inputstream stream = null;     url rssurl = new url(urlstring);     httpurlconnection conn = (httpurlconnection) rssurl.openconnection();     conn.setreadtimeout(10000 /* milliseconds */);     conn.setconnecttimeout(15000 /* milliseconds */);     conn.setrequestmethod("get");     conn.setdoinput(true);     // starts query     conn.connect();     stream = conn.getinputstream();  

then use stream in parse method
