RxJava as event bus is called multiple times even when only once triggered

Asked 2021-Jun-10 at 13:42

I am trying to implement the RxJava event bus, where my use case is to get triggered when subscribed and when the event is sent. But with my code even when I send the event once, I am receiving multiple events. It is working fine for the first time, it is behaving weirdly from the second time I login into my application. i.e; For the first time desired code implemented once, for the second time it implemented two time and so on.

How to wait for images to finish processing before reloading data of collection view?

Asked 2020-Sep-27 at 11:13

I am using the new image picker API in iOS 14 and would like to be able to finish my for-loop processing of the images before calling my code at the bottom which updates my data sources and then finally reloads the data of the collection view. Currently, the code at the bottom gets called before the totalConversionsCompleted even hits 1.

how to set different fields from observing a publisher?

Asked 2020-Aug-31 at 06:07

while observing the upload function that sets Ids for pictures in some table I need to set those Ids for profilePictreId and wallpaperPictureId properties. I didn't find any solutions and flatMap or other functions were too hard to understand. I can get the ids as I mentioned below but I need them to be saparated so I can put them in different fields. either give me a solution or a good document. don't worry about other functions in code I only need the separation function for Rx while subscribing. thank you

More Explain: after uploading I need two properties to be set but I only should do it in subscribing method onSuccessUpload. I tried many ways but I get both Ids set to profilePictureId and wallpaperPictureId that is a problem they should be separated.

The subscribe function returns a Subscription object that allows you to manage the created relationship between the observable and the subscriber.

You have only one subscriber so the best thing you can do is to add imageType in your API response like,

IndexOutOfBoundsException: Inconsistency detected error while scrolling

Asked 2020-Jul-03 at 12:18

I have a list which is coming from an API which I'm storing in db. Now I'm fetching list from db and showing it in recyclerview. Then removing all data one-by-one from recyclerview listing. This process is being repeated every 10 seconds using JobScheduler. While I'm scrolling, I'm getting this error. I've tried many solutions given in various SO posts like this but it didn't worked.

ANSWER

Answered 2020-Jul-03 at 12:18

You pass your messageList to the adapter, so the messageList in the adapter and in the activity are the same object references. Then, as I understand, somehow method fetchMessageList is called, it's where the problem appears. You call .clear() on your list and start an asynchronous operation to fetch a new list, to then synchronously post it to your adapter.

The thing is, after you have cleared your list, your adapter keeps the reference to an empty list now, without being notified about the changes. The adapter still "thinks" that your list is the same size as it was before, so when you scroll the RecyclerView, it tries to call at least onBindViewHolder for new appearing items. But, as the list is empty, it throws IndexOutOfBoundsException.

You could try to notify the adapter about the changes immediately after calling messageList.clear(), but it seems to me that just deleting this clearing will solve the problem.

QUESTION

Flutter Firebase Google Sign In not working. Stops after account selection

Asked 2020-Jan-22 at 15:04

I am currently trying to implement google sign in and authentication within my app. I have set up a project and created an app in Firebase, put the google-services.json in the application, added the necessary plugin to build.gradle, and set the SHA-1 key in firebase. Email authentication is working great, however google authentication is causing problems.

All authentication is done from an 'authentication' package I have created. It contains an authentication page and performs all auth logic. The 'main' flutter app which is run, imports this package for use. This 'main' project's build.gradle files contain the additions for the google services plugin (com.google.gms:google-services:4.3.2). Once the 'main' project is run it checks if the user is currently logged in. If not it passes control to the 'authentication' package to display an auth screen and handle the login.

The problem occurs after selecting the google account I want to login with. Once the account is selected, the account selection dialog closes and nothing happens after that. The user is not authenticated (confirmed in Firebase), no exceptions are thrown, and the try-catch surrounding everything does not catch any exceptions. It seems as if all execution of the function halts. I can still move through the app, but the sign in method never finishes execution.

You can see the sign in method below. After the execution of the line final GoogleSignInAccount googleSignInAccount = await googleSignIn.signIn(); execution does not continue for some reason.

Just to turn my previous comment into an official answer:

Initial comment:

There doesn't seem to be anything wrong with the code above. I have nearly identical code that works, with the same version of the google_sign_in plugin. What I would do is debug the native code of the plugin in order to figure out where it gets stuck and then understand why that happens. Given the PlatformException that you mentioned, and after having a quick glance at the plugin's code, it definitely gets stuck somewhere between the onActivityResult callback when selecting the account to sign in with, and sending the result back to Flutter.

After author replied:

It turns out that the author had customized the app's starting Activity such that onActivityResult was no longer calling super.onActivityResult, which prevented the google_sign_in plugin from sending data from the native side back to the Flutter side.

The same mechanism is used whenever an Intent that is meant to return data is launched, such as requesting permissions, or taking a photo with a different app.

onBackpressurDrop is always ready to receive items thus onBackpressureBuffer has no practical effect in your setup. onBackpressurBuffer(int) would fail on overflow so you'd never se the expected behavior with it. In addition, concatMap fetches 2 items upfront by default so it will get source items 1 and 2.

Instead, try using the overload with the backpressure strategy configurable:
