Android intent.putExtra java.lang.illegalArgumentException -


i have class called adviewed implements parcelable.

here code:

public class adviewed implements parcelable {      protected long timestamp;     protected string country, city, lat, lng, ad_id, poster_id, user_id, latlng;      public void hydrate(hashmap<string, ?> map){         method[] methodes = this.getclass().getmethods();         iterator = map.keyset().iterator();         while(it.hasnext()){             object key = it.next();             object value = map.get(key);             string values = value.tostring();              string method = "set" + key.tostring();              for(method methode : methodes){                 if(methode.getname().equals(method)){                     try{                         methode.invoke(adviewed.this,  values);                     }                     catch(invocationtargetexception e){                         e.printstacktrace();                     }                     catch(illegalaccessexception e){                         e.printstacktrace();                     }                 }             }         }     }      public adviewed(long timestamp1, string country1, string city1, string lat1, string lng1, string ad_id1, string poster_id1,                     string user_id1, string latlng1){         this.timestamp = timestamp1;         this.country = country1;         this.city = city1;         this.lat = lat1;         this.lng = lng1;         this.ad_id = ad_id1;         this.poster_id = poster_id1;         this.user_id = user_id1;         this.latlng = latlng1;     }      public adviewed(){         this.timestamp = 0 ;         this.country = "";         this.city = "";         this.lat = "";         this.lng = "";         this.ad_id = "";         this.poster_id = "";         this.user_id = "";         this.latlng = "";     }      public adviewed(hashmap<string, ?> map){         this.timestamp = 0;         this.country = "";         this.city = "";         this.lat = "";         this.lng = "";         this.ad_id = "";         this.poster_id = "";         this.user_id = "";         this.latlng = "";          if(!map.isempty()){             this.hydrate(map);             //erreurs = new arraylist();         }     }       @override     public int describecontents(){         return 0;     }      @override     public void writetoparcel(parcel dest, int flags){         dest.writelong(timestamp);         dest.writestring(country);         dest.writestring(city);         dest.writestring(lat);         dest.writestring(lng);         dest.writestring(ad_id);         dest.writestring(poster_id);         dest.writestring(user_id);         dest.writestring(latlng);     }      public static final parcelable.creator<adviewed> creator = new parcelable.creator<adviewed>(){         @override         public adviewed createfromparcel(parcel source) {             return new adviewed(source);         }          @override         public adviewed[] newarray(int size) {             return new adviewed[size];         }      };      public adviewed(parcel in){         timestamp = in.readlong();         country = in.readstring();         city = in.readstring();         lat = in.readstring();         lng = in.readstring();         ad_id = in.readstring();         poster_id = in.readstring();         user_id = in.readstring();         latlng = in.readstring();     }      public long gettimestamp() {         return timestamp;     }      public void settimestamp(long timestamp) {         this.timestamp = timestamp;     }      public string getcountry() {         return country;     }      public void setcountry(string country) {         this.country = country;     }      public string getcity() {         return city;     }      public void setcity(string city) {         this.city = city;     }      public string getlat() {         return lat;     }      public void setlat(string lat) {         this.lat = lat;     }      public string getlng() {         return lng;     }      public void setlng(string lng) {         this.lng = lng;     }      public string getad_id() {         return ad_id;     }      public void setad_id(string ad_id) {         this.ad_id = ad_id;     }      public string getposter_id() {         return poster_id;     }      public void setposter_id(string poster_id) {         this.poster_id = poster_id;     }      public string getuser_id() {         return user_id;     }      public void setuser_id(string user_id) {         this.user_id = user_id;     }      public string getlatlng() {         return latlng;     }      public void setlatlng(string latlng) {         this.latlng = latlng;     } }

and have class adindeal derives adviewed. here code:

i have activity, let's call activitya. activitya use intent go activity (which call activityb).

here code activitya:

adindeal adindeal = new adindeal(111111111, "canada", "torronto", "43.620595", "-79.376129", "id1",  "poster_id1" , "user_id1", "43.620595, -79.376129", "10", "100", "1000", "imgpath1")  intent intent = new intent(activitya.this, activityb.class); intent.putextra("text1", "a small text"); intent.putextra("text2", adindeal);//if delete line have no problem startactivity(intent);

here code activityb:

intent mintent = getintent();  if(mintent != null){   string mtext = mintent.getstringextra("text1");   adindeal madindeal = mintent.getparcelableextra("text2");   toast.maketext(this, madindeal.getqte(), toast.length_long).show(); }

when compile , run code, illegalargumentexception.

depending on debugger, comes line:

adindeal madindeal = mintent.getparcelableextra("text2");

in activityb.

but found out problem in activitya @ line:

intent.putextra("text2", adindeal);

why happening?

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 ...
