Ionic 3 MS ADAL data validation

Ionic Framework ionic-v3
1

I’m using Ionic 3 MS ADAL and its returning data. But the thing is, when we apply Adal service in a web application, it stores data by default. But for a ionic 3 app, how could I store data or validating the stored data?? Every time its asking for the user name and password.

Below is my working Code for MS ADAL with Ionic 3.

const SsoConfig = {
      "authority": "https://login.windows.net/common",
      "resourceUrl": "https://graph.windows.net",
      "clientId": [clientId]
      "redirectUrl": "https://login.microsoftonline.com/common/oauth2/nativeclient"
    };

let authContext: AuthenticationContext = this.msAdal.createAuthenticationContext(SsoConfig.authority);
authContext.acquireTokenAsync(SsoConfig.resourceUrl, SsoConfig.clientId, SsoConfig.redirectUrl, "", "")
      .then((authResponse: AuthenticationResult) => {
        console.log(authResponse);
      })
      .catch((e: any) => {
        console.log('Authentication failed')
      });

Now, with the above code I have to login every time. Its not storing the data. So, I tried with the below code, but its not working.

authContext.tokenCache.readItems().then(function (catchItems: any) {
      if (catchItems.length > 0) {
        authority = catchItems[0].authority;
        console.log(catchItems);
      }

      authContext.acquireTokenSilentAsync(SsoConfig.resourceUrl, SsoConfig.clientId, "")
        .then((silentAuthResponse: AuthenticationResult) => {
          console.log(silentAuthResponse);
        })
        .catch((e: any) => {          
          authContext.acquireTokenAsync(SsoConfig.resourceUrl, SsoConfig.clientId, SsoConfig.redirectUrl, "", "")
            .then((authResponse: AuthenticationResult) => {              
              console.log(authResponse);
            })
            .catch((e: any) => {
              this.Message = "Authentication failed";
              console.log(e)
            });
        });;
    });

Could someone help me on this??
