How to get SAML Token from WebView in Android

Following code can be used to get SAML token Id from SAML

 //Calling method to display Token id from the SAML Reponse
view.loadUrl("javascript:window.HtmlViewer.showHTML(document.getElementsByName('SAMLResponse')[0].value);");

don't forget to use below inner class

class MyJavaScriptInterface {

        private Context ctx;

        MyJavaScriptInterface(Context ctx) {
            this.ctx = ctx;
        }

        @JavascriptInterface
        public void showHTML(String html) {
            System.out.println("html>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>:"+html);
            new AlertDialog.Builder(ctx).setTitle("Token Id").setMessage(html)
                    .setPositiveButton(android.R.string.ok, null).setCancelable(false).create().show();
        }

    }

How to check if Application is installed in Android Device

We can use below code to check if the Package com.package.name is installed in the Android Device. If not then we can direct the user to google Play Store link for the same.

Intent intent = getPackageManager().getLaunchIntentForPackage("com.package.name");
if (intent != null) {
// We found the activity now start the activity
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
} else {
// Bring user to the market or let them choose an app?
intent = new Intent(Intent.ACTION_VIEW);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.setData(Uri.parse(""https://play.google.com/store/apps/details?id=com.package.name"));
startActivity(intent);

ORA-28002: the password will expire

When you get below error from Oracle DB it indicate its time for you to change the Password. However you can get ride of this message if you set the password expired field as unlimited. I am using sqldeveloper hence showing you the UI screen wise navigation to do the same.

A database warning was encountered performing the requested operation:

ORA-28002: the password will expire within 7 days
28002. 00000 - "the password will expire within %s days"
*Cause: The user's account is about to expire and the password
needs to be changed
*Action: change the password or contact the DBA
Vendor code 28002

Use another user to log into any database connection you have, you can also use the default "system" or "sys" username.

Open connection tree and find the "Other Users" node and open that like so :
Image-1

Find your username in the child notes under "Other Users" and right click to edit user like so:

Type in your new password and Un-check password expired, then apply. Right click edit user again to see if the settings were changed if you wish.
