I faced same issue, it happens in Android, but works well in IOS. I guess this issue about Flipper Network.

For while, I commented

initializeFlipper(this, getReactNativeHost().getReactInstanceManager())

in this file /android/app/src/main/java/com/{your_project}/MainApplication.java

Whoever is still struggling with this issue. it's happening because of Flipper network plugin. I disabled it and things work just fine.

My workaround to make this work is commenting out line number 43

Try setting up the toggle-dark-mode event handler once when you start your Electron app.

Your code doesn't need to be in the ready event even.

Internally, the EvenEmitter hold an array of listeners for each event type. When you emit an event type, the EvenEmitter just goes through it's array of listeners and execute it. Therefore, the listeners are executed in the order it was added by addListener or on method.

To answer your questions there are two parts: a) it executes in the order you added the listener and b) it depends if the listeners are async or not. If your listeners are synchronous, then you can expect that behavior. If your listeners are async, you can't expect that. Even if your execute your async synchronously, they will not necessarily resolve at the same time because it's the nature of being async.

I don't think you need to use new Blog in your test, it will create an instance of Mongoose document (the weird object in your log). Create a Mongoose document is the job of the API. You only need to send the Javascript object.

RxJava sequences are synchronous by default thus the subscribe call above will run your emission code right there. To achieve the interleaving, you need a way to tell the source when both consumers are ready to receive. This can be done several ways:

I followed the answer in this question and it worked for me, but I still don't fully understand why it didn't work on first addition then it worked on the next ones previously.

I won't do a better job explaining than the article I used to look into this a little while back but I think the term you're hunting for is executor.

The function passed to new Promise is called the executor. When new Promise is created, the executor runs automatically. It contains the producing code which should eventually produce the result. In terms of the analogy above: the executor is the “singer”.

Its arguments resolve and reject are callbacks provided by JavaScript itself. Our code is only inside the executor.

When the executor obtains the result, be it soon or late, doesn’t matter, it should call one of these callbacks:

resolve(value) — if the job is finished successfully, with result value. reject(error) — if an error has occurred, error is the error object. So to summarize: the executor runs automatically and attempts to perform a job. When it is finished with the attempt, it calls resolve if it was successful or reject if there was an error.

The issue is that if the first Promise rejects, the second Promise is never part of the Promise chain that has the catch

Two possible solutions ...

One way to handle this is separately add a "dummy" catch to the second promise

Try to use PublishSubject, seems like it was created for cases like yours.
