android - How to Confirm that Child Activity has been finished before starting that child again? -


i have parent activity has 2 childs activities b , c. when open parent activity decides child activity have open. (function using startactivityforresult) eg. decide open b. b plays video , return result back. thats fine next if decide open b again. b not opening fine (not playing video).

note: following fine:

a-->b , a<--b

then

a-->c , a<--c

then

a-->b , a<--b

but following not working:

a-->b , a<--b

then

a-->b , a<--b //when try move again on b. think calling b again before finished

then

a-->c , a<--c

any idea solve problem??

mean how can child activity has beed finished before calling child again??

following code of parent activity:

@override     protected void onactivityresult(int requestcode, int resultcode, intent data) {         super.onactivityresult(requestcode, resultcode, data);         log.d(constants.tag,"requestcode: "+requestcode+" : resultcode : "+ resultcode);         finishactivity(requestcode);         playprogram(requestcode);     }      private void playprogram(int requestcode){         if(requestcode == question_wrapper){             currentchap = currentchap + 1;             intent intent = new intent(moviewrapperactivity.this, videowrapperactivity.class);             intent.putextra("chaptertoplay", currentchap);             intent.putextra("videofile",  constants.mcourse.getmchapters().get(currentchap).getvideourl());             startactivityforresult(intent, movie_wrapper);         }else if(requestcode == movie_wrapper) {             if(constants.mcourse.getmchapters().get(currentchap).isquiz()){                 intent in2 = new intent(moviewrapperactivity.this, questionwrapper.class);                 in2.putextra("chaptertoplay", currentchap);                 startactivityforresult(in2, question_wrapper);              }else{                 currentchap = currentchap + 1;                 intent intent = new intent(moviewrapperactivity.this, videowrapperactivity.class);                 intent.putextra("chaptertoplay", currentchap);                 intent.putextra("videofile",  constants.mcourse.getmchapters().get(currentchap).getvideourl());                 startactivityforresult(intent, movie_wrapper);             }         }     }

code of b:

protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     if (!io.vov.vitamio.libschecker.checkvitamiolibs(this))         return;     setcontentview(r.layout.videoview);     init();     mvideoview = (videoview) findviewbyid(r.id.surface_view);     mvideoview.setvideopath(videopath);     mvideoview.setvideoquality(mediaplayer.videoquality_high);     mcontroller = new mediacontroller(this);     mvideoview.setmediacontroller(mcontroller);     mvideoview.setoncompletionlistener(new oncompletionlistener() {          @override         public void oncompletion(mediaplayer arg0) {             log.d(constants.tag,"completed");             intent returnintent = new intent();             setresult(result_ok, returnintent);             mvideoview = null;             mcontroller = null;             finish();         }     }); }

i think media elements in b taking time destroy or not being destroyed.

intent output = new intent();     output.putextra("data", data);     setresult(activity.result_ok  , output);     finish();

just call finish() after setting result.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
