Answer 1

Use this piece of code

       GetDetailsHandler detailsHandler = new GetDetailsHandler() {
     @Override
     public void onSuccess(CognitoUserDetails cognitoUserDetails) {
        CognitoUserAttributes cognitoUserAttributes=cognitoUserDetails.getAttributes();
        stringStringHashMap=new HashMap<>();
        stringStringHashMap =cognitoUserAttributes.getAttributes();
         userNumber=stringStringHashMap.get("phone_number");
        e1.setText(userNumber);

        Log.d("Response"," Inside DEATILS HANDLER");
        // Store details in the AppHandler
        AppHelper.setUserDetails(cognitoUserDetails);
        // Trusted devices?
        handleTrustedDevice();
       // e1.setText(input.getText().toString());
         }

         @Override
          public void onFailure(Exception exception) {
        closeWaitDialog();
        showDialogMessage("Could not fetch user details!", AppHelper.formatException(exception), true);
        }
       };
     private void getDetails() {
    AppHelper.getPool().getUser(username).getDetailsInBackground(detailsHandler);
      }
