java - Android Multiple Permissions Error -


i have method should check if permission need have granted or not :

public boolean checkcamera(){     string[] permissions= new string[]{             manifest.permission.write_external_storage,             manifest.permission.camera};      int result;     list<string> listpermissionsneeded = new arraylist<>();     (string p:permissions) {         result = contextcompat.checkselfpermission(getapplicationcontext(),p);         if (result != packagemanager.permission_granted) {             listpermissionsneeded.add(p);         }     }     if (!listpermissionsneeded.isempty()) {         activitycompat.requestpermissions(this, listpermissionsneeded.toarray(new string[listpermissionsneeded.size()]),multiple_permissions );         return false;     }     return true; }

if not, request these permissions. problem is, if denied 1 of them pass valid permission.

private void requestpermissioncamera(){     if(checkcamera()){         values.put(mediastore.images.media.title, "new picture");         values.put(mediastore.images.media.description, "from camera");         imageuri = getcontentresolver().insert(                 mediastore.images.media.external_content_uri, values);          intent intent = new intent(mediastore.action_image_capture);         intent.putextra(mediastore.extra_output, imageuri);         startactivityforresult(intent,requestcodecamera);     } }

in moment checks, it's not returning false should , on requestresult same thing.

@override public void onrequestpermissionsresult(int requestcode, @nonnull string[] permissions, @nonnull int[] grantresults) {     switch (requestcode){         case multiple_permissions:             if(grantresults.length > 0 && grantresults[0] == packagemanager.permission_granted){                  values.put(mediastore.images.media.title, "new picture");                 values.put(mediastore.images.media.description, "from camera");                 imageuri = getcontentresolver().insert(                         mediastore.images.media.external_content_uri, values);                  intent intent = new intent(mediastore.action_image_capture);                 intent.putextra(mediastore.extra_output, imageuri);                 startactivityforresult(intent,requestcodecamera);             } else {                 toast.maketext(this, "not permissions granted", toast.length_short).show();             }             break;          case read_storage:

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 ...
