Android Bluetooth connectiong using createInsecureRfcommSocketToServiceRecord or createRfcommSocketToServiceRecord On a Samsung Device Android 7 -


i have problems connecting bluetooth device samsung galaxy devices android 6 or 7. same code working on other devices android 7 , htc m9 example.

my code far:

         try {             adapter.canceldiscovery();              socket = device.createinsecurerfcommsockettoservicerecord(btuuid);             socket.connect();              publishprogress(context.getstring(r.string.bt_con_established));              int r;             byte[] s = new byte[256];             bufferedinputstream in = new bufferedinputstream(socket.getinputstream());              while(!iscancelled() && (r = in.read(s)) != -1) {                 publishprogress(new string(s, 0, r));             }         } catch (ioexception e) {             e.printstacktrace();             if(!iscancelled()) {                 return context.getstring(r.string.bt_con_error);             }         } {             try {                 if(socket != null) {                     socket.close();                 }             } catch (ioexception e) {                 e.printstacktrace();                 return context.getstring(r.string.bt_con_not_closed);             }         }

i receive issocketallowedbysecuritypolicy.

someone have idea, why not working on samsung devices? there special security rules on samsung or knox devices?

i used uuid 0000110e-0000-1000-8000-00805f9b34fb same error.

many thanks

transpose - Maple isnt executing function but prints function term -

im using maple im in worksheetmode tried using maple input , 2d input , want transpose matrix a: := `<|>`(`<,>`(1, .5, -2), `<,>`(.5, 9/4+b, 5+3*b), `<,>`(-2, 5+3*b, 18+9*b+4*a)); b:= transpose(a); when exectute sheet dont translated values, there same input. matrix looks same input matrix plus function term. you can see picture in following link: why arent functions executed? meanwhile b:=a^+ doing right way , transposed matrix. other functions return function body instead needed values... if using 2d input mode (the default) space you've got between transpose , bracketed (b) interpreted multiplcation. rid of such space. also, either load package @ start of document like, with(linearalgebra): before calling transpose command package, or call it's full name like, linearalgebra:-transpose(b);
