I tried upgrading Android Gradle Plugin from 4.2.2 to 7.0.1 using the upgrade assistant which is available in Android Studio at Tools > AGP Upgrade Assistant. The only change it made was to my project-level build.gradle file:...
ANSWERAnswered 2021-Aug-24 at 16:35
the Android Gradle Plugin documentation still says classpath 'com.android.tools.build:gradle:4.2.0' instead of 7.0.1.
Is this a bug in Android Gradle Plugin 7.0.1?
Quite possibly. Or, perhaps beyond, as the
Instantiatable Lint check has a history of problems.
If your scenario does not match one of those three August 2021 bugs, and you are in position to provide a reproducible test case, file a fresh issue! Beyond that, if a clean-and-rebuild is not clearing up your problem, you might need to simply disable the
Instantiatable Lint check for the time being by adding the following to all of your build.gradle files at the application or library level (i.e. all except your project-level build.gradle):
I have encountered strange redirect behaviour after returning a RedirectResponse object

When you want to redirect to a GET after a POST, the best practice is to redirect with a
303 status code, so just update your code to:
How to make dynamic key with other static Key types in typescript. For Eg....
ANSWERAnswered 2022-Mar-17 at 16:41
Ideally, split those off into a sub-object on
RecordDto instead of having them directly on
RecordDto. (For instance, a
tabs property with the type
Record.) But if you can't or don't want to do that:
Provided you can distinguish the index keys from the other keys based on their name, it will work as you have it with a slight tweak. For instance, your key is a number followed by
_tab and none of your other properties fits that pattern, so a template literal type works for the key of the index signature and differentiates those from the other property names:
I have these tables...
ANSWERAnswered 2022-Jan-27 at 09:47
Lateral joins come in handy when dealing with JSON or XML.
I usually retrieve the data I need from the various tables in lateral queries. For example :
I am developing an Sports Mobile App with flutter (mobile client) that tracks it's users activity data. After tracking an activity (swimming, running, walking ...) it calls a REST API developed by me (with springboot) passing that activity data with a POST. Then, my user will be able to view the logs of his tracked activities calling the REST API with a GET.
As I know that my own tracking development isn't as good as Strava, Garmin, Huawei and so on ones, I want to let my app users to connect with their Strava, Garmin and so on accounts to get their activities data, so I need users to authorize my app to get that data using OAuth.
In a first approach, I have managed to develop all the flow of OAuth with flutter using the Authorization Code Grant. The authorization server login is launched by flutter in a user agent (chrome tab), and once the resource owner has done the login and authorize my flutter app, my flutter app takes the authorization code and the calls to the authorization server to get the tokens . So I can say, that my client is my flutter App. When the oauth flow is done, I send the tokens to my Rest API in order to store them in a database.
My first idea was to send those tokens to my backend app in order to store them in a database and develop a process that takes those tokens, consult resource servers, parses each resource server json response actifvities to my rest API activity model ones and store in my database. Then, if a resource owner consults its activities calling my Rest API, he would get a response with all the activities (the mobiles app tracked ones + Strava, Garmin, resource servers etc ones stores in my db).
I have discarded the option to do the call to the resource servers directly from my client and to my rest api when a user pushes a syncronize button and mapping those responses directly in my client because I need the data of those resource servers responses in the backend in order to implement a medal functionality. Further more, Strava, Garmin, etc have limits of usage and I don't want to let my resource owners the hability to push the button the times they want.
Here is the flow of my first idea:
Client calls the authorization server launching a user agent to an oauth login. In order to make the resource owner login and authorize. The url and the params are hardcoded are hardcoded in my client.
Resource owner logins and authorize client.
Callback is sent with code.
Client captures code of the callback and makes a post to he authorization server to get the tokens. As some authorization servers accept PKCE, I am using PKCE when its possible, to avoid attacks and hardcoding my client secret in my client. Others like Strava's, don't allow PKCE, so I have to hardcode the client secret in my client in order to get the tokens.
Once the tokens are returned to my client, I send them to my rest api and store in a database identifying the tokens resource owner.
To call the resource server:
One periodic process takes the tokens of each resource owner and updates my database with the activities returned from each resource server.
The resource owner calls the rest api and obtains all the activities.
The problem to this first idea is that some of the authorization servers allow implementing PKCE (Fitbit) and others use the client secret to create the tokens (Strava). As I need the client secret to get the tokens for some of those authorization servers, I have hardcoded the secrets in the client and that is not secure.
I know that it is dangerous to insert the client secrets into the client as a hacker can decompile my client and get the client secret. I can't figure how to get the resource owner tokens of Strava without hardcoding the client secret if PKCE is not allowed in the authorization server.
As I don't want to hardcode my client secrets in my client because it is insafe and I want to store the tokens in my db, I dont see my first approach as a good option. Further more, I am creating a POST request to my REST API in order to store the access token and refresh token in my database and if i am not wrong, that process can be done directly from the backend.
I am in the situation that I have developed a public client (mobile app) that has hardcoded the client secrets because I can't figure how to avoid doing that when PKCE isn't allowed by the authorization server to get the tokens.
So after thinking on all those problems, my second idea is to take advantage of my REST API and do the call to the authorization server from there. So my client would be confidential and I would do the OAuth flow with a Server-side Application.
My idea is based on this image.
In order to avoid the client secret hardcoding in my mobile client, could the following code flow based on the image work and be safe to connect to Strava, Garmin, Polar....?
Strava connection example:
Mobile public Client Calls my Rest API to get as a result the URI of Strava Authorization server login with needed params such as: callback, redirect_uri, client_it, etc.
Mobile client Catches the Rest API GET response URI.
Mobile client launches a user agent (Chrome custom tab) and listen to the callback.
The login prompt to strava is shown to the resource owner.
The resource owner inserts credentials and pushes authorize.
Callback is launched
When my client detects the callback, return to client and stract the code from the callback uri.
Send that code to my REST API with a post. (https://myrestapi with the code in the body)
REST API CLIENT
Now, the client is my REST API, as it is going to be the one that calls the authorization server with the code obtained by the mobile client. The client will take that code and with the client secret hardcoded in it will call to the Authorization server. With this approach, the client secret is no more in the mobile client, so it is confidential.
The authorization server returns the tokens and I store them in a database.
- Takes those tokens from my database and make calls to the resource servers of strava to get the activities. Then parses those activities to my model and stores them into the database.
Is this second approach a good way to handle the client secrets in order to avoid making them public? Or I am doing something wrong? Whatr flow could I follow to do it in the right way? I am really stuck with this case, and as I am new to OAuth world I am overwhelmed with all the information I have read....
ANSWERAnswered 2022-Jan-25 at 12:54
From what I understand, the main concern here is, you want to avoid hardcoding of client secret.
I am taking keycloak as an example for the authorization server, but this would be same in other authorization server as well since the implementation have to follow the standards
In the authrization servers there are two types of client's one is the
1.Confidential client - These are the one's that require both client-id and client-secret to be passed in your Rest api call
The CURL would be like this, client secret required

I'm currently studying Jetpack Compose in an attempt to build a feature-rich application using modern Android architecture components. Traditionally, each screen (or navigation unit) in my application would be either an activity or a fragment, each with its own lifecycle bindings, but with Jetpack Compose and the Compose Navigation library, I would do something like this:
ANSWERAnswered 2021-Aug-29 at 04:50
The Compose application is designed to be used in a single-activity architecture with no fragments.
You can still have multiple activities or fragments and use
setContent in each of them, but in this case the transfer of data between activities falls on your shoulders. Use this approach if you're adding new Compose screens to an existing application built the old way.
But with Compose, it's much easier to do all the navigation within a single activity using Compose Navigation. Much less code, better performance due to no unnecessary code layers, easy to transfer data, etc.
To work with the view lifecycle, check out compose side-effects:
LaunchedEffectcan be used to execute an action when the view appears. It also runs on a coroutine context that is bound to the current composable: you can easily run suspend functions, and when the view disappears from view hierarchy - the coroutine will be canceled.
DisposableEffectcan be used to subscribe to/unsubscribe from callbacks.
When you rotate the screen, all effects will restart no matter which key you passed.
I am developing an app where the app will detect Bluetooth signals (Sensoro Smart Beacon device) and open the activity. But I want the app to still be able to detect the signal even when the application on the background or even when killed. I used a foreground service, it detects the signal when I open the application and move between activities but when sending the app to the background and opening other applications, the listener stops although the service still working. I am printing the logs.
System.out.println("Sensoro 2" ); keeps printing even when I kill the application or open another application. But the printing logs in BeaconManagerListener are not working. I tried to use background service but it didn't work also.
Can you please advise if there is a way to make the listener works in a service when the app in background or killed?
Here is the service code:
ANSWERAnswered 2021-Nov-18 at 07:15
I looked at the Android rules and regulations page
According to Google documents, from Android 8 onwards, all applications that do not have a Google-approved signature will be removed from the background after a few minutes.
But the solutions:
- The first solution is to run the application in debug mode
- The second solution is to assign a signature to the application and send it to Google for approval
- The third solution is to remove the google play service application from the emulator or android phone
