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.

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:

• Grant a GCP service-account access to Drive API and use Cloud Functions to access it.

• Instead use Cloud Storage, which is within the Firebase eco-system and is similar to Drive.

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.

I've found the issue, in the jar task I had to add

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:

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.

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:

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

‘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.

request

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.
