In Android Studio Pdf/.doc file is corrupted after downloading it from Download Manager -


1) after downloading .docx/pdf file in android studio through download manager shows me message "unreadable content in file. want recover it?"
2) when download jpg or mp3, works fine.

my code:

private long downloaddata (uri uri, view v) {      long downloadreference;      downloadmanager = (downloadmanager)getsystemservice(download_service);     downloadmanager.request request = new downloadmanager.request(uri);      //setting title of request     request.settitle("zoraizcv");     request.setallowednetworktypes(downloadmanager.request.network_wifi | downloadmanager.request.network_mobile);     request.setnotificationvisibility(downloadmanager.request.visibility_visible_notify_completed);      //setting description of request     request.setdescription("android data download using downloadmanager.");      //set local destination downloaded file path within application's external files directory     if(v.getid() == r.id.downloadmusic)       request.setdestinationinexternalfilesdir(mainactivity.this, environment.directory_downloads,"zoraizcv.docx");       request.allowscanningbymediascanner();     //enqueue download , save referenceid     downloadreference = downloadmanager.enqueue(request);        button downloadstatus = (button) findviewbyid(r.id.downloadstatus);     downloadstatus.setenabled(true);     button canceldownload = (button) findviewbyid(r.id.canceldownload);     canceldownload.setenabled(true);      return downloadreference; }

public class puneuniversity_mechanical_engineering_se extends appcompatactivity { // remove below line after defining own ad unit id. private static button btn_download; downloadmanager downloadmanager;

@override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_puneuniversity_mechanical__engineering__se);      // load ad admob banner view.     adview adview = (adview) findviewbyid(r.id.adview);     adrequest adrequest = new adrequest.builder()             .setrequestagent("android_studio:ad_template").build();     adview.loadad(adrequest);     btn_download=(button)findviewbyid(r.id.download);     btn_download.setonclicklistener(             new view.onclicklistener() {                 @override                 public void onclick(view view) {                     downloadmanager= (downloadmanager) getsystemservice(context.download_service);                     uri uri= uri.parse("https://drive.google.com/uc?export=download&id=0b6c5vnwhm0scsvlxz3ljtna3tjg");                     downloadmanager.request request=new downloadmanager.request(uri);                     request.setnotificationvisibility(downloadmanager.request.visibility_visible_notify_completed);                     long reference=downloadmanager.enqueue(request);                  }             }     );   }

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 ...
