I did react-native run-ios.It's success. but stopping at the splash screen.

I use react native .

I try it. and reload.

How fix it?

I built my responsive online game using html&css, javascript and php. I'm planning to export it as an android application. Because I don't have enough knowledge of languages for android development (I used react native but I'm not comfortable with it), I'll try to export my app in WebView / I'll make hybrid application.

I built it in React Native, it works, but I'm not happy with speed. It looks like there is 0.5s delay every time when I click button or slide.

My question is: Which programming language will do it in best way? Is it possible to speed up react native webview a little bit?

How to properly link a user to reviews page at App Store app in React Native application on iOS?

This is still something that is required, I see this message all the time, but it's completely invalid from what I have experienced. Almost every package I work with, I still have to run the react-native link.

Can anyone tell me what's up with this? Is it just particular packages, or why do I still need to run react-native link all the time, when it tells me I shouldn't run it. I mean, it's really just adding it to the pod file for iOS and gradle for Android.

Anyone else experiencing this?

I have a view which has overlapping views, the root view is an absolute view while the child views which is the buttons shown below is relative, the upper side of the buttons is touchable but the bottom side marked in yellow is not, therefore onPress is not triggered:

Code used for this:

I have read online websites that this is an issue with react-native it does not support overlapping views.Any workaround that can be done to avoid this kind of issue or bug in react-native?

I have been into the process of upgrading react-native version from 0.59.1 to 0.62.0, since RN 0.60.0 all the native libraries are linked automatically using pods. I had to include these lines in podfile require_relative '../node_modules/@react-native-community/cli-platform-ios/native_modules' and use_native_modules!, why is it necessary to add these lines ?

I am testing my React Native app using Appium and WebdriverIO. Having difficulty in changing slider values.

Normally in XCUITest I can easily achieve this using the following code:

app.sliders["slider-red"].adjust(toNormalizedSliderPosition: 0)

How to do the equivalent in Appium/WebdriverIO? I read somewhere that I should call sendKeys(). I tried the following:

$('~slider-red').sendKeys(['0']);

But it is giving me the following error:

invalid element state: Error Domain=com.facebook.WebDriverAgent Code=1 "The on-screen keyboard must be present to send keys"

It looks like sendKeys is for input fields, not for sliders!

I've implemented react-native-background-fetch in my app, and it works well on Android, but not on ios - Xcode Version 11.4

Simulate Background Fetch works. I noticed also that Background Fetch triggers once on the first application start, but not anymore. On Android Background Fetch triggers every 15 min.

My configuration is:

react-native: 0.62.1

react-native-background-fetch: 2.8.0

Here is my code:

App.js

class App extends Component {  componentDidMount () {    ...    newPostNotificationService.initNotifications()    ...

newPostsNotificationSevice.js

initNotifications = async () => {  this.configureNotifications() // Configures PushNotification  BackgroundFetch.registerHeadlessTask(this.fetchNewPosts)  BackgroundFetch.configure({    minimumFetchInterval: 15,    stopOnTerminate: false,    startOnBoot: true,    enableHeadless: true  }, this.fetchNewPosts,    (error) => {      console.log(error, '[js] RNBackgroundFetch failed to start')    })  BackgroundFetch.status((status) => {    switch (status) {      case BackgroundFetch.STATUS_RESTRICTED:        console.log('BackgroundFetch restricted')        break      case BackgroundFetch.STATUS_DENIED:        console.log('BackgroundFetch denied')        break      case BackgroundFetch.STATUS_AVAILABLE:        console.log('BackgroundFetch is enabled')        break    }  })}

fetchNewPosts Method in newPostsNotificationSevice.js

async fetchNewPosts(taskId) {  console.log('BackgroundFetch Start', taskId)  if (AppState.currentState === 'active') {    BackgroundFetch.finish(taskId)    return  }  dataStorageService.getSettings().then(async (settings) => {    if (!settings.notifications) {      BackgroundFetch.finish(taskId)      return    }    const url = config.API_URL + config.API_ENDPOINTS.POSTS +'&per_page=1&page=1'    let data    if (!config.DATA_MOCK.NEW_POSTS) {      data = await fetch(url)        .then((response) => {          return response.json()        })        .catch((error) => {          console.error(error)        })    } else {      data = postsMock.posts    }    data = data.map(item => {      return new PostShort(item)    })    data = data.filter(item => {      return item.sendPush    })    if (data.length === 0) {      BackgroundFetch.finish(taskId)    }    dataStorageService.getPostsIndex().then(postsIndex => {      if (postsIndex.length > 0 && postsIndex.indexOf(data[0].id) !== -1) {        BackgroundFetch.finish(taskId)        return      }      dataStorageService.getNotificationsIndex().then(notificationsIndex => {        if (notificationsIndex.indexOf(data[0].id) !== -1) {          BackgroundFetch.finish(taskId)          return        }        const notificationBody = entities.decode(data[0].title)        const notificationNumber = notificationsIndex.length + 1        console.log('notificationNumber', notificationNumber)        PushNotification.localNotification({          title: config.NOTIFICATION_TITLE, // (optional)          message: notificationBody, // (required)          playSound: true, // (optional) default: true          soundName: 'default',          number: notificationNumber,          id: notificationNumber.toString()        })        dataStorageService.insertIntoNotificationsIndex([data[0].id])        BackgroundFetch.finish(taskId)      })    })  })}

I made iOS setup following this instructions: https://github.com/transistorsoft/react-native-background-fetch/blob/HEAD/docs/INSTALL-AUTO-IOS.md

Why Background Fetch doesn't trigger periodically on iOS like on Android does?

EDIT START:

I found a solution:

in your XCode you need to found Build phases link, then Link Binary With Libraries select lRCTBlob and click -(minus) in the end of list

EDIT END

currently trying to upgrade react-native to 0.61.5 from 0.59.10 and faced this error:

ld: library not found for -lRCTBlob

clang: error: linker command failed with exit code 1 (use -v to see invocation)

I've tried pod install, pod install --repo-update, pod update and that:

1. Clear the cache of pod with:

   1.1 rm -rf ~/Library/Caches/CocoaPods

   1.2 rm -rf Pods

   1.3 rm -rf ~/Library/Developer/Xcode/DerivedData/*

   1.4 pod deintegrate

   1.5 pod setup

2. And delete the project's Pods directory. The location of it is project directory > ios > Pods.
3. Then in the project directory > ios location, install pod with pod install
4. And react-native run-ios in project directory.

Any help welcome!

I'm trying to use a prepopulated SQLite DB for my react native app. I'm using Expo and the downloadAsync() Function to load my DB from my assets folder. This works as expected on IOS, as I can load the DB and retrieve the data.

On Android however I just can't get this to work. The db file is there in the internal storage of my emulator, but every time I try to retrieve data, an error occurs since 'there is no such table'.

My guess is that SQLite doesn't properly search for my db but instead creates a new one, where my tables are obviously missing.

I've been trying for over 7 hours now, so I appreciate any kind of help.

Folder structure:

App.js-assets--db---db.db-src--connection---connectionClass

App.js

const App = () => {    const [dbLoaded, setDbLoaded] = useState(false);       if(!dbLoaded){        downloadDB().then((value) => setDbLoaded(value));        return <></>    } else {        return (<Navigation/>        );    }};

ConnectionClass.js

export const downloadDB = async () => {    await FileSystem.deleteAsync(`${FileSystem.documentDirectory}SQLite`, {idempotent : true});    await FileSystem.makeDirectoryAsync(`${FileSystem.documentDirectory}SQLite`, {intermediates: true });    return await FileSystem.downloadAsync(        Asset.fromModule(require('../../assets/db/WaKanji.db')).uri,        `${FileSystem.documentDirectory}SQLite/WaKanji.db`    ).then(({status}) => {        if(status === 200){                           return true        }        return false    }).catch(error => {        console.log('Err\n'+ error);        return false;    });};

All in a sudden when i tried to add new pods to the Podfile and tried to install them, the process is getting infinite!

Here is the log:

And it gets stuck here and when i checked the activity indicator a process called git-remote-https is continuosly fetching the source from the repo, but it doesnt end either! Why so?? How to fix it

In my React Native app, I'm trying to make an API call with this code:

test = async () => {    try {      let a = await fetch('https://rxapitest.alliancepharmacygroup.ca:12345/', {        method: 'GET',      }).then(response => {        console.log("success")      })    } catch(err) {      console.log("error")    }  }

On Android this works fine. In Postman the request works fine. And when I replace the URL with https://google.com or something, it works fine. So it seems that the problem is with this particular URL for iOS only.

Here's my stacktrace:

Does anyone know how I can approach this?

I'm sure I'm missing something simple. I have a React Native project working and I'm attempting to get it on the app stores. Following those instructions, after I have created my provisioning profile in the Apple Developer Dashboard, it says to double click the developer provisioning profile to launch xcode. It's these instructions exactly:

Now find the files you just downloaded on your computer, and double-click each of them in turn, causing Xcode to launch. Verify the profiles are there by opening a project or starting a new one for this test.

So I double-click my file, and xcode does launch but no windows open up. I do not have an xcode project for my react native app so I have nothing to open. There is no menus for 'build settings' or 'general' so I'm not sure how to proceed.

For reference, here is my react native directory structure:

my_project/    .expo/    assets/    node_modules/    src/    .bablerc    .gitignore    App.js    app.json    package-lock.json    package.json    README.md

Did I miss a step somewhere? How do I get an xcode project from this?

This is really annoying me. if i use http://my-domain.com its work with out Network request failed, but https://my-domain.com its keep giving me Network request failed error.

i been looking online and still not fix this issue. Please help.

I have a React Native app.

I realized I didn't inject any code to restart app in certain condition
(e.g. when update detected, force restart, reload)

Is there anyway to apply updates to apps in users devices?
Like by command line specifying device id or something?

Thank you.

I want to fetchdata from server when my app closed (in background || died) and stop fetching when it again opened.

So I need to call a function right after app goes to backgroundstate or even force closed (died) and stop it when comes again to foreground.

How can I do it with react-native to be work on both Android and IOS?

I prefer if it is possible without any third party libs, because most third party libs are not maintained in long term.
