java - App crashes when calling startActivityForResult -
i'm working on first android app, in case me cook better. have 2 activities i'm struggling with, mainactivity.java , whatcanimake.java. when start whatcanimake mainactivity using startactivity(intent), i'm able pass objects using parcelables , use whatcanimake. issue want able pass list of i've changed in whatcanimake activity. example: pass in list of ingredients have, , whatcanimake removes ingredients recipe uses. i'd pass updated list of remaining ingredients.
the problem i'm having startactivityforresult(). able use startactivity(), pass intent parcelables, , bob's uncle. when changed on startactivityforresult(), new activity fails launch, app crashes before hitting oncreate(). points implementation of startactivityforresult(), i've read every stack overflow question related startactivityforresult() , i'm here!
my code starting whatcanimake below, onactivityresult() , corresponding code inside whatcanimake.
it's odd me can change out startactivityforresult() startactivity() , app works again! in advance.
mainactivity.java:
public void searchrecipe(view view) { crossviewvariables.setmakesort('a'); intent recipe = new intent(this, whatcanimake.class); recipe.putextra("pantry",stock); recipe.putextra("cookbook",activecookbook); recipe.setflags(intent.flag_activity_forward_result); startactivityforresult(recipe,r.integer.search_by_recipe); //startactivity(recipe); } @override protected void onactivityresult(int requestcode, int resultcode, intent data) { switch(requestcode) { case (r.integer.search_by_recipe)://comes recipe search? if (resultcode == activity.result_ok) { bundle b = data.getextras(); stock = b.getparcelable("pantry"); } if (resultcode == activity.result_canceled) { } case (r.integer.search_by_ingredient)://comes recipe search? if (resultcode == activity.result_ok) { bundle b = data.getextras(); stock = b.getparcelable("pantry"); } if (resultcode == activity.result_canceled) { } case (r.integer.make_recipe)://comes seerecipe? if (resultcode == activity.result_ok) { bundle b = data.getextras(); stock = b.getparcelable("pantry"); } if (resultcode == activity.result_canceled) { toast.maketext(getapplicationcontext(), "cancelled", toast.length_long).show(); } case (r.integer.edit_pantry): if (resultcode == activity.result_ok) { bundle b = data.getextras(); stock = b.getparcelable("pantry"); } } } whatcanimake.java:
intent result = new intent(); result.putextra("pantry", stock); setresult(activity.result_ok,result); finish(); logcat:

remove line:
recipe.setflags(intent.flag_activity_forward_result); you not need startactivityforresult(), , it's causing crash.
