expo

问题 I developed an app with React Native and distributed it with Expo. I published the final version into Google Play and Apple Store. Some time later I discovered in Expo's docs on Publishing that expo publish allows you to create an OTA ("over the air") update that is built into Expo and updates the app automatically, according to this answer: The standalone app knows to look for updates at your app's published url. This I tested and worked very well. However, now I see that people downloading

问题 I have to eject from expo in my react native project, but I still want to maintain some functionalities provided by their libraries, like notifications. Is it possible? Thanks in advance! 回答1: Starting with SDK33 Expo was changed to install its own modules separately as required.

Check whether a module is available on MainApplication.java for Android or info.list for ios.

问题 After using expo's ImagePicker and saving the image in the local cache, I am trying to save the image to firebase storage (or its new name, Cloud Storage for Firebase).

Client Side : const { uri } = await this.camera.takePictureAsync(options); let formData = new FormData(); formData.append('file', { uri: uri.replace("file:///", ""), type:'image/jpg', name:'userProfile.jpg', }); const

Im using this code, the only difference is that im using expo kit, so my MainApplication.java is different (inherits from another class by default): public class MainApplication extends MultiDexApplication { // Needed for `react-native link` public List<ReactPackage> getPackages() { return Arrays.<ReactPackage>asList( new MainReactPackage(), new

问题 I am creating a react native app using expo, and I am creating a dropdown in the header. On iOS the dropdown works as desired, and goes 'above' the main content, while on Android it is clipped or goes 'under'. I am not sure if in reality iOS is acting strange, or Android is.

问题 I am sorry for the black marks in the image. I have seen multiple posts suggesting an answer to this problem, Lock unlocks keychain (tried it), pod Update (tried it), clear build(tried it), signing, skip install in build settings(tried it) - None of them actually worked. I built my iOS app in react native with Expo, after which I did expo eject to create the iOS folder for Xcode build and archiving, the build is successful every time and it even runs on the simulator and in my device(iPhone 7
