java - Want to login to Router with android application -
i'm starting develop android application , want try connect router. wrote application using jackson, stuck json request login router. ip of router 192.168.1.1 , username , password should taken edittext fields. android.os.networkonmainthreadexception
there json string login:
{ "jsonrpc": "2.0", "id": 1, "method": "call", "params": [ "00000000000000000000000000000000", "session", "login", { "username": "root", "password": "admin01" } ] }
this restrequest.java
public class restrequest { private static final string tag = jacksonutil.class.getsimplename(); static string response = null; public final static int = 1; public final static int post = 2; //constructor no parameter public restrequest(){ } public string makewebservicecall(string url, int requestmethod){ return this.makewebservicecall(url, requestmethod, null); } public string makewebservicecall(string urladdress, int requestmethod, hashmap<string, string> params){ url url; string responce = ""; try { url = new url(urladdress); httpurlconnection urlconnection = (httpurlconnection) url.openconnection(); urlconnection.setreadtimeout(15000); urlconnection.setconnecttimeout(15000); urlconnection.setdoinput(true); urlconnection.setdooutput(true); if(requestmethod == post){ urlconnection.setrequestmethod("post"); }else if(requestmethod == get){ urlconnection.setrequestmethod("get"); } if(params != null){ outputstream outputstream = urlconnection.getoutputstream(); bufferedwriter bufferedwriter = new bufferedwriter( new outputstreamwriter(outputstream, "utf-8")); stringbuilder result = new stringbuilder(); boolean first = true; for(map.entry<string, string> entry : params.entryset()){ if (first) first = false; else result.append("&"); result.append(urlencoder.encode(entry.getkey(), "utf-8")); result.append("="); result.append(urlencoder.encode(entry.getvalue(), "utf-8")); } bufferedwriter.write(result.tostring()); bufferedwriter.flush(); bufferedwriter.close(); outputstream.close(); } int responcecode = urlconnection.getresponsecode(); if(responcecode == httpsurlconnection.http_ok){ string line; bufferedreader br = new bufferedreader(new inputstreamreader(urlconnection.getinputstream())); while ((line = br.readline()) != null){ responce += line; } }else { responce = ""; } } catch (exception e){ log.e(tag, "ioexception parsing json", e); } return response; } edited loginactivity.java can @ activity , tell i'm doing wrong
public class loginactivity extends appcompatactivity { private string page_url = "http://192.168.1.1/ubus"; @bind(r.id.user_name_edit_text) textview user_name; @bind(r.id.user_password_edit_text) textview user_password; @bind(r.id.login_button) button login_button; @override protected void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.activity_login); butterknife.bind(this); login_button.setonclicklistener(new view.onclicklistener() { @override public void onclick(view view) { string url = page_url; string username = getusername(); string password = getpassword(); trytologin trytologin = new trytologin(); trytologin.execute(url, username, password); } }); class trytologin extends asynctask<string, void, void>{ @override protected void doinbackground(string... params) { url url = null; try { url = new url(page_url); } catch (malformedurlexception e) { e.printstacktrace(); } urlconnection connection = null; try { connection = url.openconnection(); } catch (ioexception e) { e.printstacktrace(); } try { connection.connect(); } catch (ioexception e) { e.printstacktrace(); } return null; } public string getusername() { string username = user_name.gettext().tostring(); return username; } private string getpassword() { string password = user_password.gettext().tostring(); return password; }
you cannot make network calls using main thread in android - design ensure ui thread remains responsive , not wait. need perform call in asyncthread or normal thread
