android - Trouble with firebase and facebook login -


my problem sign facebook got error firebase authentication,the method signinwithcredential(authcredencial credencial) in oncompletelistener result of task not successful , can't understand why.

@override protected void oncreate(bundle savedinstancestate) {     ....     callbackmanager = callbackmanager.factory.create();     loginbutton.setreadpermissions("email", "public_profile");     loginbutton.registercallback(callbackmanager, new facebookcallback<loginresult>() {         @override         public void onsuccess(loginresult loginresult) {             system.out.println("entro");             handlefacebookaccesstoken(loginresult.getaccesstoken());         }     ...     });      firebaseauth = firebaseauth.getinstance();     firebaseauthlistener = new firebaseauth.authstatelistener() {         @override         public void onauthstatechanged(@nonnull firebaseauth firebaseauth) {             firebaseuser user = firebaseauth.getcurrentuser();             if (user != null) {                 // user signed in                 log.d("tag", "onauthstatechanged:signed_in:" + user.getuid());             }         }     }; }  private void handlefacebookaccesstoken(accesstoken accesstoken) {      authcredential credential = facebookauthprovider.getcredential(accesstoken.gettoken());        firebaseauth.signinwithcredential(credential).addoncompletelistener(this, new oncompletelistener<authresult>() {          @override         public void oncomplete(@nonnull task<authresult> task) {             log.d("tag","terminoooooooooooooooooooooooooooooooooooo");             if (!task.issuccessful()){                 toast.maketext(this, "error al iniciar en firebase", toast.length_short).show();         }      }); }

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);
