java - Android use Broadcast Receivers to send value -


i have accessibilityservice class:

public class ussdservice extends accessibilityservice { public static string tag = "ussdservice"; public string responsee=""; @override public void onaccessibilityevent(accessibilityevent event) {     log.d(tag, "onaccessibilityevent");     string text = event.gettext().tostring();      if (event.getclassname().equals("android.app.alertdialog")) {         performglobalaction(global_action_back);         log.d(tag, text);         intent intent = new intent("message");         intent.putextra("value", text);         toast.maketext  (this,text,toast.length_long).show();          this.sendbroadcast(intent);// write broad cast receiver , call sendbroadcast() here, if want parse message balance, date     }  }  @override public void oninterrupt() { }  @override protected void onserviceconnected() {     super.onserviceconnected();     log.d(tag, "onserviceconnected");     accessibilityserviceinfo info = new accessibilityserviceinfo();     info.flags = accessibilityserviceinfo.default;     info.packagenames = new string[]{"com.android.phone"};     info.eventtypes = accessibilityevent.type_window_state_changed;     info.feedbacktype = accessibilityserviceinfo.feedback_generic;     setserviceinfo(info); }}

as can see in method onaccessibilityevent, send intent using method sendbroadcast.

in mainactivity use broadcastreceiver receive value this:

public class mainactivity extends appcompatactivity {  private broadcastreceiver breceiver = new broadcastreceiver(){      @override     public void onreceive(context context, intent intent) {         //put here whaterver want activity intent received         log.i("onreceive",intent.getstringextra("value") );     } };  protected void onresume(){     super.onresume();     log.i("onresume", "22222");     localbroadcastmanager.getinstance(this).registerreceiver(breceiver, new intentfilter("message")); }  protected void onpause (){     super.onpause();     log.i("onpause", "11111");      localbroadcastmanager.getinstance(this).unregisterreceiver(breceiver); } @override protected void oncreate(bundle savedinstancestate) {      super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_main);}}

my app works fine when call ussd method onaccessibilityevent work , value show in toast, method onreceive did not work , don't know problem is. please me.

intent intent = new intent(); intent.setaction("com.example.broadcast.my_notification"); intent.putextra("message"); localbroadcastmanager.getinstance(this).sendbroadcast(intent‌​);

from android: "the intent's action string must provide app's java package name syntax , uniquely identify broadcast event."

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

jquery - Responsive Navbar with Sub Navbar -

good day, forgive me nav vocabulary not best. if question confusing apologize. i'm working on navigation bar needs centered on page @ 768px , above. items in nav open (or perhaps toggle) subnav lives directly below. these nav should appear centered on page. i have been able work through responsive portion of nav bar, having main items align vertically , sub nav menu of each item roll out below, , gave them indent separation. working well. however, issue not responsive side, behavior @ width greater 768px. happens toggling menu's sub navigation pushes other main items down page below sub nav. here's code: $(document).ready(function () { //stick in fixed 100% height behind navbar don't wrap $('#slide-nav.navbar-inverse').after($('<div class="inverse" id="navbar-height-col"></div>')); $('#slide-nav.navbar-default').after($('<div id="navbar-height-col"></d
