How to enable mobile hotspot programmatically in marshmallow and above android version? -


i've tried create wifi tethering hotspot in android marshmallow using following code.

public class wifiaccessmanager {  private static final string ssid = "mhotspot"; public static boolean setwifiapstate(context context, boolean enabled) {     //config = preconditions.checknotnull(config);     try {         wifimanager mwifimanager = (wifimanager) context.getsystemservice(context.wifi_service);         if (enabled) {             mwifimanager.setwifienabled(false);         }         wificonfiguration conf = getwifiapconfiguration();         mwifimanager.addnetwork(conf);          return (boolean) mwifimanager.getclass().getmethod("setwifiapenabled", wificonfiguration.class, boolean.class).invoke(mwifimanager, conf, enabled);     } catch (exception e) {         e.printstacktrace();         return false;     } }  public static wificonfiguration getwifiapconfiguration() {     wificonfiguration conf = new wificonfiguration();     conf.ssid =  ssid;     conf.allowedkeymanagement.set(integer.parseint("12345678"));     return conf; }

}

and have given permission access wifi in manifest file

<uses-permission android:name="android.permission.access_wifi_state" /> <uses-permission android:name="android.permission.change_wifi_state" /> <uses-permission android:name="android.permission.write_settings" /> <uses-permission android:name="android.permission.change_network_state" /> <uses-permission android:name="android.permission.internet" /> <uses-permission android:name="android.permission.access_network_state" />

but it's not activating in marshmallow , above version.

whenever enabling hotspot got error

kindly solve issue.

thanks

the issue, log, this:

caused by: java.lang.securityexception: com.example.deneebo.ffconnect not granted  permission: android.permission.write_settings

your app requires android.permission.write_settings permission, , in marshmallow permission cannot granted declaring in manifest. change did enforce security.

you have ask user allow app use permission explicitly. can find more info in this answer.

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
