I'm trying to get location on android device But it crashes immediately after execution -


i'm trying location on android device code follows:

private void openlocation() {     lm = (locationmanager)getsystemservice(context.location_service);     criteria c = new criteria();     pro = lm.getbestprovider(c,false);     location l = lm.getlastknownlocation(pro);      if (l != null) {         toast.maketext(webactivity.this, "longitude : "+string.valueof(l.getlongitude())+", latitude : "+string.valueof(l.getlatitude()), toast.length_long).show();     } else {         toast.maketext(webactivity.this,"loc object null",toast.length_long).show();     }      mgac = new googleapiclient.builder(this)             .addconnectioncallbacks(this)             .addonconnectionfailedlistener(this)             .addapi(locationservices.api)             .build(); }

but crashes when executed. what's wrong in code, or please give me working code give me location string , want send data url using get/post request , request should run in background.

this might u,

thread thread = new thread(new runnable() {             @override             public void run() {              try {                  url url = new url(url);                 httpurlconnection conn = (httpurlconnection) url                         .openconnection();                 conn.setreadtimeout(10000 /* milliseconds */);                 conn.setconnecttimeout(15000 /* milliseconds */);                 conn.setrequestmethod("get");                 conn.setdoinput(true);                 // starts query                  conn.connect();                 inputstream stream = conn.getinputstream();                  string data = convertstreamtostring(stream);                  // u can read data here                 stream.close();               } catch (exception e) {             }         }     });      thread.start();

& convertstreamtostring is,

static string convertstreamtostring(java.io.inputstream is) {         java.util.scanner s = new java.util.scanner(is).usedelimiter("\\a");         return s.hasnext() ? s.next() : "";     }

this can in sending request server in background getting location i'm not sure.
