first of please add following code in manifest
<uses-permission android:name="android.permission.internet"/> then put networking code either in thread or in doinbackground method of async task.
this solve problem.
you can call current async task using
new loadstuff.execute("url"); public class loadsomestuff extends asynctask<string, integer, string>{ string result=null; @override protected string doinbackground(string... params) { // todo auto-generated method stub //proberen met internet te connecten try{ //maak nieuw client object httpclient httpclient = new defaulthttpclient(); //post onze url, site voorbeeld httppost httppost = new httppost("http://ephemeraltech.com/demo/android_tutorial20.php"); //voor post uit en response httpresponse response = httpclient.execute(httppost); //get message response httpentity entity = response.getentity(); //get content van message inputstream webs = entity.getcontent(); //nu hebben response, convert string try { bufferedreader reader = new bufferedreader(new inputstreamreader(webs, "iso-8859-1"), 8); //text view removed here result=reader.readline(); //sluiten webs.close(); }catch(exception e){ log.e("log_tag", "error converting result "+e.tostring()); } }catch(exception e){ log.e("log_tag", "error in http connection "+e.tostring()); } return null; } onpostexecute(){ //declare text view here & assign result text view. mytextview.settext(result); } }
