https - SSL handshake error in Volley android -


i trying ssl pining volley library web server accepts connection valid certificate. getting ssl handshake error. using code below loading certificate:

        certificatefactory cf = null;         cf = certificatefactory.getinstance("x.509");      // https://www.washington.edu/itconnect/security/ca/load-der.crt     inputstream cainput = context.getresources().openrawresource(r.raw.ssl_bundle);     certificate ca;     try {         ca = cf.generatecertificate(cainput);         system.out.println("ca=" + ((x509certificate) ca).getsubjectdn());     } {         cainput.close();     }      // create keystore containing our trusted cas     string keystoretype = keystore.getdefaulttype();     keystore keystore = keystore.getinstance(keystoretype);     keystore.load(null, null);     keystore.setcertificateentry("ca", ca);      // create trustmanager trusts cas in our keystore     string tmfalgorithm = trustmanagerfactory.getdefaultalgorithm();     trustmanagerfactory tmf = trustmanagerfactory.getinstance(tmfalgorithm);     tmf.init(keystore);      // create sslcontext uses our trustmanager     sslcontext sslcontext = sslcontext.getinstance("tlsv1");     sslcontext.init(null, tmf.gettrustmanagers(), null);      return  new nosslv3socketfactory(sslcontext.getsocketfactory());

and getting below error:
