android - Can't start Application to particular activity on Notification click from FCM -


i'm experiencing problem: if click on notification , app closed, homeactivity opened instead of requested one.

i'm raising notification this:

intent intent = new intent(context, articleactivity_.class); intent.putextra(articleactivity.key_article_id, articleid); intent.setflags(intent.flag_activity_new_task); pendingintent pendingintent = pendingintent.getactivity(context, 0 , intent,             pendingintent.flag_update_current);   uri defaultsounduri= ringtonemanager.getdefaulturi(ringtonemanager.type_notification); notificationcompat.builder notificationbuilder = new notificationcompat.builder(context)             .setsmallicon(r.drawable.ic_launcher)             .setcontenttitle(notification.gettitle())             .setcontenttext(notification.getbody())             .setautocancel(true)             .setsound(defaultsounduri)             .setcontentintent(pendingintent);  notification n = notificationbuilder.build(); n.flags |= notification.flag_auto_cancel;  notificationmanager notificationmanager =             (notificationmanager) context.getsystemservice(context.notification_service);  notificationmanager.notify(0 , n);

and works fine if application opened. if close it, after clicking on notification, homeactivity opened instead of 1 configured.

you having problem because how fcm works. there 2 types of push notifications. first type "notification" , second type "data". both can visualize json payload:

"notification": {     //key values }  "data": {     //your custom key values }

there third type combination of both.

the "notification" type create default visual notification default behavior when app not in foreground. , execute whatever write inside onmessagereceived when app open. second type "data" code inside onmessagereceived.

from firebase web console, can send "notification" type or combined type. sending "data" need send firebase functions or server (that complies fcm requisites).

there trick can goal. combined payload, can send firebase web console, contains "notification" , "data". "data" key-values available after user click notification. information available data intent opening default launcher activity, there can change activity.

in launcher activity, add following:

string notification = getintent().getstringextra("your-key"); if (notification != null) {     startactivity(new intent(this, youractivity.class)); }

this way can validate activity being opened because default notification clicked, , string because payload in push fcm must rule string. in other cases, if user opened app, string null, , don't redirect user.

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer
