android - Preloading Fragments when App starts -


i'm using app navigation drawer menu, , want of fragments created when app starts, of fragments fetch data web service , not want user have wait of data load right when go screen. work around this, want create of fragments @ once , hide them, , afterwards display correct fragment.

  private void initfragments() {     fragmentmanager fmanager = getfragmentmanager();     fragmenttransaction ftransaction = fmanager.begintransaction();     (int = 0; < main_fragments; i++) {         ftransaction.add(r.id.frame_container, fragmentarray[i], fragmenttags[i]);     }     ftransaction.commit();     fmanager.executependingtransactions(); } private void hidefragments(){     fragmentmanager fmanager = getfragmentmanager();     fragmenttransaction ftransaction = fmanager.begintransaction();     (int = 0; < main_fragments; i++) {         ftransaction.hide(fmanager.findfragmentbytag(fragmenttags[i]));     }     ftransaction.commit();     fmanager.executependingtransactions(); }

my way work around create of fragments , hide them calling

initfragments() hidefragments()

however, i've noticed when run on emulator, on devices correctly show 1 fragment, rest being added hidden. on other devices, show of fragments overlaid ontop of eachother resulting in ugly mess. furthermore, when use app on landscape device such tablet, fragments overlap eachother have forced app portrait mode. ideas on best way go this?

are getting errors?

i suspect devices/versions might not support findfragmentbytag() method, or hide() method matter. try looking that.

with regard overlapping problem on tablets, try this: https://stackoverflow.com/a/11086185/2929693

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.
