i try make http connection ibm service response. looks it's impossible do. how can fix it?

your problems quite common android beginner. log, android.os.networkonmainthreadexception stated doing network task on main thread not allowable. have network task in background otherwise can't away errors. can fix problems wrapping current code asynctask.

 private class myasycntask extends asynctask<string, string, string> {      private string process = null;       protected string doinbackground(string... urls) {         // network task in background          httpresponse res = makerequest(urls[0]);          this.process = processrequest(res);           return getbodyfromresponse(res);      }       protected void onpostexecute(string responsebody) {          // ui task in main thread          showdialog("downloaded " + result + " bytes");      }       /*          rest of code below here          ....      */  }

you should understand relationship between background , main thread, or else can't understand why asynctask needed in networking. more details asynctask, please take looks @ docs.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
