android - Activity is destroyed after coming back from camera app -

-

i have activity dialog. in dialog when click on imageview default camera app launches , when create photo , click tick icon (at least it's tick icon on phone) previous activity recreated, destroyed , recreated again. happens 1 in 10 times.

this happens

1. intent opens camera 2. onpause() 3. onsaveinstancestate runs 4. onstop() 5. ondestroy()  6. camera app opens, picture taken , click tick 7. onstart﹕() 8. onrestoreinstancestate runs 9. onresume() 10. onpause() 11. onsaveinstancestate 12. onstop() 13. ondestroy() 14. onstart﹕() 15. onrestoreinstancestate

so if save data need in onsaveinstancestate (step 3) , retrieved in onrestoreinstancestate (step 8), it's lost when activity destroyed (i use flag decide if want save data , flag becomes null when activity recreated second time). save in sharedpreferences, still, undesired function want correct.

if matters, here's code:

intent

btn_camera.setonclicklistener(new view.onclicklistener() {    @override    public void onclick(view arg0) {    which_dialog = "complete";    complete_dialog.dismiss();    imagefileforcamera_ = gettemporarydirectory();    intent intentpicture = new intent(mediastore.action_image_capture);    if (imagefileforcamera_ != null) {       intentpicture.putextra(mediastore.extra_output, uri.fromfile(imagefileforcamera_));    } startactivityforresult(intentpicture,pick_from_camera_complete_kitkat);

onactivityresult:

case pick_from_camera_complete_kitkat:   selectedimageuri = uri.fromfile(imagefileforcamera_);   complete_dialog.show();   (...more code...)

onsaveinstancestate

@override protected void onsaveinstancestate(bundle outstate) {     super.onsaveinstancestate(outstate);     if (which_dialog != null && which_dialog.length() > 1) {        outstate.putstring("which_dialog", which_dialog);        outstate.putserializable(instance_state_image_file_for_camera, imagefileforcamera_);     } else {        log.i("onsaveinstancestate which_dialog", "which_dialog null");     } }

onrestoreinstancestate

@override protected void onrestoreinstancestate(bundle savedinstancestate) {     super.onrestoreinstancestate(savedinstancestate);     if (savedinstancestate != null) {         if (savedinstancestate.containskey("which_dialog")) {            if (savedinstancestate.getstring("which_dialog").equals("complete")) {                complete_dialog = new completedialog(activity.this);                imagefileforcamera_ = (file)savedinstancestate.getserializable(instance_state_image_file_for_camera);             }         }     } else {          log.i("onrestoreinstancestate", "savedinstancestate null");     } }

you saving which_dialog in onsaveinstancestate(). not restoring which_dialog in onrestoreinstancestate(). modify onrestoreinstancestate() set which_dialog based on value saved in onsaveinstancestate().

[C++][SFML 2.2] Strange Performance Issues - Moving Mouse Lowers CPU Usage -

-
i've been working on making 2d map editor past 2 weeks or so, , i've run strange problem. trying optimize code, example, making functions should've been functions begin with, did made cpu usage go through roof. i've tried commenting out different sections of code thought culprits (scrolling, rendering, other calculations) no avail. think issue might trying call things within different functions, sake of making modular possible, i'd functionality. the other major change i've made since file i'm comparing i've ported variables external cpp file, since having variables global makes lot easier use within different functions. simple issue, can't life of me understand why happens. with original code, around 2-3% cpu usage. new code, around 20-35%, but, if move mouse around, it'll drop around 6-8%. tl;dr: after trying optimize code using functions, i've somehow killed performance, , found strange quirk moving mouse reduces cpu usage.. /...
