Using bundle in Async Task,android -


how values bundle in asynctask doinbackground() method, consist of url , string?

in activity:

bundle bundle = new bundle(); bundle.putstring("url", url); bundle.putstring("json",asyn.tostring()); inte.putextras(bundle); jsonobject responsefromserver = asyn.execute(bundle);

and in asynctask not still able extract values.

there no need use bundle here, can pass in strings varargs doinbackground() takes.

you call this, json jsonobject:

 asyn.execute(url, json.tostring());

then, make doinbackground() take string varargs:

class asyn extends asynctask<string, void, void> {     @override     protected void doinbackground(string... arg0) {         string url = arg0[0];         string json = arg0[1];         jsonobject obj = new jsonobject(json);     }    }

if want use bundle, call now:

bundle bundle = new bundle(); bundle.putstring("url", url); bundle.putstring("json",json.tostring()); //inte.putextras(bundle); //not needed asyn.execute(bundle);

then make doinbackground() take bundle varargs:

class asyn extends asynctask<bundle, void, void> {     @override     protected void doinbackground(bundle... arg0) {         bundle b = arg0[0];         string url = b.getstring("url");         string json = b.getstring("json");         jsonobject obj = new jsonobject(json);     }    }

in addition, should not trying capture return value asynctask. if asynctask subclass of activity, set value in onpostexecute(), , call method in enclosing activity.

for other ways it, see post.

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.
