I'm currently working on an application in React Native. I need to be able to read and manage audios for my project.
I find the documentation for Expo AV rather badly done, there is a lack of examples of use.
To make it simple, I want to get the didJustFinish value (boolean). To do so, I created a loop using setOnPlaybackStatusUpdate but I don't understand how to get the didJustFinish value back afterwards.
Okay, I found the solution.
Here's an example:
yourSoundObject.setOnPlaybackStatusUpdate((playbackStatus) => {
console.log(playbackStatus.didJustFinish)
console.log(playbackStatus.positionMillis)
})
playbackStatus is a property that is only added in the function called by setOnPlaybackStatusUpdate.
For ease of use I've done this in an anonymous function

I would like to create a box to select the date as in the attached photo.
What do you recommend to create something similar in react native with expo?
I tried using MUI's Mobile DatePicker API, but it doesn't work, errors occur.
Update:
I created this box to select the date, but when I go to press it gives me an error.
The error is the following:
https://www.npmjs.com/package/#react-native-community/datetimepicker
Works with Expo. Static version set at 3.x.x (something version 3). So you won't have the full functionality that is described on their docs, but you'll have enough.
expo install #react-native-community/datetimepicker
instead of npm to ensure you get the compatible version.
This library can be a bit difficult to work with. The main suggestion I have for you is to create a custom component on your own that looks like your design. Then wrap it with a TouchableOpacity and onPress set the DateTimePicker to show its modal. Grab the value you need from the onChange result, and pass it to your local state. Dont try anything fancy after that because as I mentioned earlier, the library is difficult to work with and really fights hard against any customization. It works well though and will certainly solve your problem.
The problem
So, I am developing a react native application and I am facing the callenge of selecting multiple images from the user gallery. Just like apps like WhatsApp, Telegram, Twitter and even Reddit do. So with that in mind, i tried to use launchImageLibraryAsync from expo-image-picker but, as specified in their documentation, the "multiple selecion" of images is only supported on the web.
What I have thinked of
So, based on several searches, it seemed like i had to build my own "Gallery". To do this, so far i've tried to use #react-native-community/cameraroll and expo-media-library, but both of them requires that we pass the first property to the getPhotos (for #react-native-community/cameraroll) or to the getAssetsAsync (for expo-media-library) functions, which defines the first items to be fetched. This is a problem because I do not want to fetch like 20 items and then, when the user reaches the end of the list, it fetches more 20 items. I need something like this (this example is from Telegram). You can see that the app never stops me from scrolling, it goes all the way through my entire gallery.
What would also be nice
If you use reddit mobile, you can see that you can also select multiple photos using the several Apps like Google Photos, Files, Google Drive and so on.
This would be even nicer because I wouldn't need to implement a custom made Picker. Do you guys know how could I implement this?
OBS: I am using Expo with Bare Workflow, so I can use just about any package. I also opened a discussion at the Expo repo about it. You can check it here: https://github.com/expo/expo/discussions/15210.
Thank you in advance :)
I have been using this package called expo-images-picker check it out. It has similar function to what you need. It works in Mobile as well.

we working with expo and using mapview, however, there are many restrictions in react native maps, as we are planning to implement turn by turn navigation. Integrating Mapbox would have been the best option, however we do not think it’s best to eject the project as expo doesn’t still support Mapbox. Although, I came across a package, react native maps navigation, I would like to know if anyone has been able to successfully implement it in their project and it functioned properly, and also know if there are any drawbacks that comes along with it. I am asking this because the author says “Please note that this module is usable but still under heavy development. Some properties and/or component names might change without notice.”
Kindly give your suggestions and advice. Thanks
Mapbox works very well in a react-native projects and recommend to use this service for your project but effectively, it don't works with expo so for me, you should eject your project to use it.
I paste here some packages I used for a GPS project (The last one is to get the current position of an user)
react-native-mapbox-gl/maps
mapbox-sdk
react-native-geolocation
Hope that could help you
Problem
I'm integrating React Native into an existing Android app (ie. making a hybrid app). I've created an Activity to host a React Native view. This works fine.
Now, I need to pass structured data from native into React Native. Represented as JSON, it looks something like this:
{
"landscape": ["http://example.com/1.jpg", "http://example.com/2.jpg"],
"portrait": ["http://example.com/3.jpg", "http://example.com/4.jpg"]
}
Given the context I describe how can I make this data available as props inside of the React Native app?
I see that this is an initialProperties argument available, but it seems to accept a Bundle, which as far as I can tell (Android newbie here) only accepts scalar values.
One option I am considering
Create JSON object in Java
Convert to a string
Add to Bundle and pass into initialProperties
Ingest as JSON and deserialize in React Native app
... but this seems hackish and requires me to add special code for Android that was not required for iOS.
Alternatives?
Is there a straightforward approach that I am missing?
Have you tried passing an array of strings into the Bundle?
bundle.putStringArray("landscape",yourArrayOfStrings]);
As far as I've searched it appears to be impossible to load modules (=plugins/libraries?) dynamically (I'm very new to React Native..).
What I'd like to accomplish is to let the user of the app load additional functions as she/he desires.
Example:
A user wants to add a music plugin to the app.
Intuitively, I'd long for something like dynamic library loading. The user would fetch the library, it'll be loaded into the code and can then be executed. However, in React Native it seems like there are only modules that can be loaded?
Alternatively, I'd hope that auto-updating the app would allow to add modules "on-the-fly" ( https://github.com/aerofs/react-native-auto-updater or www.npmjs.com/package/react-native-hot-load ). But I fear that this is only for JS and data content?
The ability to dynamically add functionality to the app is an essential part of the app. I have no previous experience worth mentioning in mobile app development.
Question: Is it possible to dynamically add functionality (also native in nature) to React Native apps?
If not, would there be a workaround?
EDIT: I have found the following repository on github: https://github.com/yusefnapora/react-dynamic-linking-example .
Unfortunately, without any description. I have no idea about Objective-C, but the repo name sounds promising. Anybody knows what its purpose is?
