I'm using React Native 0.71.1 with a bare workflow and I want to get user current location. As I've seen there are many libraries to accomplish this task, two of them are:
expo-location
[react-native-geolocation-service][1]
[1]: https://github.com/Agontuk/react-native-geolocation-service
I have used the second one for long time, and use the corresponding function to prompt the popup to ask for location permission, but since I have update the react native version, the popup is presented, using both libraries, at the first time the app is open.
I don't want this behaviour, since I'd like to prompt the popup when I want, using the Geolocation.requestAuthorization("whenInUse") function provided by the library.

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.

My app is a custom image picker written in React Native using Expo, that lets a user select a particular image for uploading. When a user presses an Upload button in any third-part Web page, I want my app to open rather than the standard Android file picker dialog.
Is this possible? I'm only interested in Android at the moment. I've looked at Expo's ImagePicker, but this launches the standard Android System UI in response to a call from an app. In contrast, I need my app to open, not ImagePicker, in response to a user's click on a file upload button in a Web page.
ContentProviders looks like a promising approach, but I can't see how to use it in Expo, and I'm not sure if this is the right approach anyway.
Intents all seem to load the standard system UI image picker.
Is what I want possible, and if so, what approach should I use to achieve it?
I can't find a way to programmatically close an ActionSheetIOS. When the device orientation changes, if there is an action sheet open, I need to close it before reopening it (otherwise it is erroneously anchored to the wrong location). I haven't been able to find a way to trigger closing it without requiring user input. Is this possible programmatically?
The documentation does not mention this being possible in the current version (0.38.0). I also could not find any related issue, so the only ideas that comes to mind are either finding a package that implements the functionality JS.coach, or extending the implementation of ActionSheetIOS to include that functionality. Maybe this question might be helpful.
React Native version 0.69.0 has added the ActionSheetIOS.dismissActionSheet() method, which will dismiss the most upper action sheet.
I want to add login items programmatically in Mountain Lion (10.8).
Until now I was able to add login items by editing this plist:
/Users/test/Library/Preferences/loginwindow.plist
and adding items (path,name,hide) to AutoLaunchedApplicationDictionary dictionary
in the OS doesn't work anymore. Items that are added to this dictionary are not launched on login. I see that the login items are saved in a file called: com.apple.loginitems.plist
but I don't understand how to add an item to this file. I tried to add the item to CustomListItems dictionary with parameters like name,path, hide but they were not launched on login.
Does anyone know how can I add from code login item?
I understand you want to start your program automatically when your user logs in.
In older versions of OS X, it was possible to add login items manually by editing loginwindow.plist. Apple deprecated this approach when they added LaunchAgent and LaunchDaemon functionality to the OS.
Since you are using Mountain Lion, the correct way to have a program launch is to create a launchagent for it. This is a .plist file that you can use to tell OS X to a) perform some action (e.g.: launch /some/program.app) when b) a specific event occurs (e.g.: logging in, logging out, etc)
You will find Apple's official document on creation of LaunchAgents over here.
This looks like a great tutorial on the modern way of doing things: The launch at login sandbox project
It starts with a paragraph buried in the App Sandbox design guide:
Creating a Login Item for Your App
To create a login item for your sandboxed app, use the SMLoginItemSetEnabled function (declared in ServiceManagement/SMLoginItem.h) as described in “Adding Login Items Using the Service Management Framework” in Daemons and Services Programming Guide.
(With App Sandbox, you cannot create a login item using functions in the LSSharedFileList.h header file. For example, you cannot use the function LSSharedFileListInsertItemURL. Nor can you manipulate the state of launch services, such as by using the function LSRegisterURL.)
And rolls from there...
