asp.net - Connecting Android to web service -
this question has answer here:
i'm making android application supposed connect made localhost web service. things aren't going well. have following code:
public void proben() {
string soapmsg="<?xml version=\"1.0\" encoding=\"utf-8\"?>" + "<soap:envelope xmlns:xsi=\"http://www.w3.org/2001/xmlschema-instance\" xmlns:xsd=\"http://www.w3.org/2001/xmlschema\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">" + "<soap:body>"+ "<selectvezba xmlns=\"http://tempuri.org/\">"+ "<ime>" + "a" + "</ime>" + "</selectvezba>" + "</soap:body>" + "</soap:envelope>"; log.d("where", "before others"); textview t = (textview)findviewbyid(r.id.textview2); httpparams httpparameters = new basichttpparams(); // set timeout in milliseconds until connection established. int timeoutconnection = 15000; httpconnectionparams.setconnectiontimeout(httpparameters,timeoutconnection); // set default socket timeout (so_timeout) // in milliseconds timeout waiting data. int timeoutsocket = 35000; httpconnectionparams.setsotimeout(httpparameters, timeoutsocket); defaulthttpclient httpclient = new defaulthttpclient(httpparameters); httppost httppost = new httppost(constants.service_location); httppost.setheader("content-type", constants.content_type); httppost.setheader("soapaction", constants.get_selectvezba); log.d("where","before try"); httpentity entity; try { entity = new stringentity(soapmsg, http.utf_8); httppost.setentity(entity); } catch (unsupportedencodingexception e) { // todo auto-generated catch block log.d("where", "in catch 1"); e.printstacktrace(); } httpresponse response; try { log.d("where", "in catch 0"); response = httpclient.execute(httppost); log.d("where","1"); if(response == null) { log.d("tag","response e null"); } httpentity r_entity = response.getentity(); // response header[] headers = response.getallheaders(); if (r_entity != null) { string str_entity = entityutils.tostring(r_entity); log.d("response",str_entity); } } catch (clientprotocolexception e) { log.d("where", "in catch 2"); // todo auto-generated catch block e.printstacktrace(); } catch (ioexception e) { // todo auto-generated catch block log.d("where", "in catch 3"); e.printstacktrace(); }// calling server //parsing irrelevant question parsersaxlista parser=new parsersaxlista("nov.xml"); listview listview1 = (listview)findviewbyid(r.id.listview1); arraylist<entitet> nova=parser.objekti(); arraylist<string> lista=new arraylist<string>(); (entitet en : nova) { lista.add(en.tostring()); } arrayadapter<string> adapter = new arrayadapter<string>(this, android.r.layout.simple_list_item_1, lista); listview1.setadapter(adapter); }
the constants used defined follows:
public final static string service_location = "http://10.0.2.2:63919/servis.asmx"; public final static string content_type = "text/xml; charset=utf-8"; public final static string get_selectvezba = "http://tempuri.org/selectvezba"; in logcat, "in catch 0" , "in catch 3" tells me there's exception coming line:
response = httpclient.execute(httppost); how fix this? read elsewhere i'm supposed add internet permission in manifest, upon writing:
<uses-permission android:name="android.permission.internet"></uses-permission> in manifest, program started crashing immediately.
any appreciated. sorry such long code in question.

looking @ logcat output can see that:
(...) 07-11 09:11:11.934: e/androidruntime(1380): caused by: android.os.networkonmainthreadexception (...) at line.
this meet @selvin's comment possible duplicate of "android.os.networkonmainthreadexception".
as answer tells: asynctask solution
you should doing network work in asynctask object , pass final result (or progressresult) , asynctask object, called on ui thread (where handle ui elements/events/answers).
don't hesitate take @ : asynctask documentation .
