            How to Verify Mobile no and email id from Secure QR code of Aadhaar card
            Asked 2020-Oct-14 at 14:11

            Official Document for How to Read QR code data from Secure QR code of UIDAI Aadhaar card:

            Have used zxing scanner to scan Secure QR code, And was able to get details of aadhar card with the help of follow project in Github:

            Some how I figured out how to extract photo and bit_indicator_value from converted byte array with the help of instructions on document

            But I am unable to get hashed exact hashed value of email and mobile from Secure QR code of Aadhar card byte array to verify

            I am bit confused from this line of above mentioned document in page no 6:

            • Post getting signature value, check the value of Email_mobile_present_bit_indicator_value:
            1. if its 3 then first read mobile from index (Byte array length – 1-256) and then email from index (Byte array length – 1- 256- 32) in reverse order. Each value will be of fix size of 32 byte.
            2. If Email_mobile_present_bit_indicator_value is 1 then only mobile is present.
            3. If Email_mobile_present_bit_indicator_value is 2 then only email is present.
            4. If Email_mobile_present_bit_indicator_value is 0 then no mobile or email present.
            • Email and Mobile value will available in byte. Convert into Hexadecimal String. .

            I have also prepared last step in document page no 6 but the users mobile/email hash value and documents mobile/email byte arrays hash value never matches

            Code snippet:



            Answered 2020-Oct-14 at 11:22

            Just now got the solution, fetched exact mobile and email hash value from byte array

            first remove last 256 bytes from byte array then,

            if only mobile present then take last 32 bytes from byte array for mobile i.e. (array.length - 32 to array.length)

            else if only email present then take last 32 bytes from byte array for email i.e. (array.length - 32 to array.length)

            else if both email and mobile present then take last 32 bytes from byte array for mobile, take next last 32 bytes for email i.e. (mobile = array.length - 32 to array.length and email = array.length - 64 to array.length - 32)



            Java : Google AppEngine : OAuth : Google Drive API to access user's Google Drive contents created by Web Application
            Asked 2020-Jun-26 at 23:27

            Scenario: I am working on a Web Application on Google AppEngine where users have to access files from their own Google Drive. I have looked for online help and this is what I have figured out.

            I have used this link for help that worked fine while testing with local machine

            Step 1 (Seemed simple): Enable Google Drive API and Setup necessary credential, i.e. OAuth 2.0 Client ID for Web Application. (This is done while enabling IAP on Google AppEngine, so I did not do it again. Whenever anyone opens the web application, he/she is asked to authenticate via and details saved. This works fine). Also, I have added Google Drive Scopes to the OAuth consent screen (../auth/drive.appdata & ../auth/drive.file) that don't need verification by Google.

            Step 2: Downloaded the credentials.json from OAuth Client ID and stored inside "resources" folder created in the root of application package (inside main folder, next to java and webapp folders)

            Step 3: I have created a testing class (GoogleDriveServiceTest.class) that includes following code:



            Answered 2020-Jun-25 at 12:16

            You need to first create and store the credentials in the flow's credential store:

            createAndStoreCredential(TokenResponse response, String userId)

            to be able to load them with loadCredential(String userId)

            The loadCredential() method will return credential found in the credential store of the given user ID or null for none found.



            How to use GoogleDrive from Android app using FireBase Auth UI?
            Asked 2020-Jan-29 at 20:57

            I have implemented Firebase Authentication in my app, using the Google Provider and the "" scope so my app can access its application folder within Google Drive

            This part works fine and I retrieve the FireBaseUser once the authentication completes What I now want to do is to access my app storage on Google Drive, but I don't know how to do this using the result of the current authentication

            I tried to follow this:

            But this doesn't work on Android. The main issue is how to create the Credentials object Do you have any idea on how to initialize a Drive.Builder instance so I can write/read to the app Google Drive folder?




            Answered 2020-Jan-29 at 20:57

            This cannot be done directly, because the Firebase & Google login are not the same, even when having logged in to Firebase with a Google account. On Android one meanwhile only has the "last logged in Google account" available for the user's Drive (the one on the device, which has nothing to do with Firebase Authentication, where Google may only be used as an "Authentication Provider").

            So there are generally two options available to you:

            I could also think of a combined solution approach, where users would use Cloud Storage (together with Firebase Authentication) and having a Cloud Function which uses a service-account, which eg. copies or moves uploaded files into a folder your Drive.

            Concerning that (obviously server-side) Java example, the credentials.json clearly hints for a service account... and this is exactly where you can obtain this file from. However, for Android this is pretty useless - because it has major security implications, to package service-account credentials in an easy to de-compile package and distribute it on the WWW (to everybody). The Google Play Store likely would not permit you to publish or even upload that, because there are security checks in place. You could in best case only deploy that code as App Engine module, but not as an Android module.

            Sorry for having destroyed your delusions and for not being able to provide a ready-made solution for 500 imaginary internet points, which pay nothing - but at least I can tell what is technically possible and what isn't - which effectively might save you lots of time, trying to accomplish the impossible.

            Java multithreading: setPriority()
            Asked 2019-Feb-25 at 14:47

            I was reading online about Thread's setPriority() and came across the following:



            Answered 2017-Jun-18 at 18:17

            Every piece of code in Java is executed from an instance of a Thread.

            If you do not write your own threads everything will be executed by a java-main-thread.

            When a Java Virtual Machine starts up, there is usually a single non-daemon thread (which typically calls the method named main of some designated class). (from the Java API for Thread)

            However you can use multiple Threads across your project to make usage of multi-threading and parallelism technology on your machine.

            The method setPriority can be used to give the current thread object on which you are calling this method a priority. This priority is used by the thread scheduler of your OS to give the threads CPU time based on their priorities. So a thread with higher priority is more likely to get CPU time than one with a smaller priority.

            Again, if you are not using any self made threads you are indeed using a java-main-thread. You can always access the current thread you are in by using Thread.getCurrentThread().

            So if you have your own Thread class MyOwnThread extends Thread and write something like this:



            Creating a flexmark extension in Clojure
            Asked 2018-Aug-24 at 04:18

            I'm trying to write a small extension to flexmark. I want to create a custom AttributeProvider and am trying to work through the example shown here.

            My issue is translating two classes into Clojure.

            I've separated the two relevant example classes into separate Java source files and translated the demonstration program into a clojure test.

            The SampleAttributeProvider in Java:



            Answered 2018-Aug-24 at 04:18

            You need a forward declaration for the CWikiAttributeProvider as a return value in gen-class. Declare the class in two steps at the top of your file: 1) with constructors only, and 2) with a full declaration including (static) methods and state.



            Has SD card writing been blocked?
            Asked 2018-Apr-12 at 09:28

            I am trying to provide a functionality in my app that the media or storage files used in my application can be moved to SD card by the user.

            I am trying to use the code as described in below link


            But I get a permission exception. When I searched for getting that permission, I see that I have to root the device. I don't want to root my device, as it is illegal, no? Is there any android device model that comes rooted from the beginning itself from the manufacturer?

            Earlier also I used to see a "Move To SD Card" option in the app settings, but I don't see that option any more. I also saw that most of the file browser applications installed in my device are unable to create a folder on the SD card,

            Please share some light on what's the best recommended way to implement this feature. We are supporting android 4.4 to 8.0



            Answered 2018-Apr-12 at 08:57

            If you haven't done so already, you will need to give your app the correct permission to write to the SD Card by adding the line below to your Manifest:



            Difference between page scope and request scope in Servlet & JSP?
            Asked 2017-Sep-17 at 12:23

            I have gone through below links so far-:
            Page scope- scope in jsp
            What are the different scopes in JSP?
            difference between page and request

            I want to know about what are the differences between page scope and request scope? If I consider use of RequestDispatcher.forward() & HttpServletResponse.sendRedirect() to same or different page, then how these scopes will work?

            If request is forwarded to same page then how these two scopes will differ?



            Answered 2017-Jul-13 at 12:43

            Notice more than one page can serve a single request. see article.

            You also can see in example that you can forward a parameter with request scope to another page by forward.


            ‘page’ scope means, the JSP object can be accessed only from within the same page where it was created. The default scope for JSP objects created using tag is page. JSP implicit objects out, exception, response, pageContext, config and page have ‘page’ scope.


            A JSP object created using the ‘request’ scope can be accessed from any pages that serves that request. More than one page can serve a single request. The JSP object will be bound to the request object. Implicit object request has the ‘request’ scope.
