We were working on a react native project. One of my team members added some native modules on Linux and linked android. By then I am trying to link things in iOS but the build is always failing with this kind of error trace. The Android project is building normally.

I deleted xyz.xcworkspace and Podfile.lock then tried pod install.
Also, I tried to delete my node_modules and then yarn install followed by yarn link.

I am running a react-native application on Mac. but I am getting "RNCSafeAreaView" was not found in the UIManager.

Boa noite, alguém poderia me explicar se já conseguiu usar o ionicicon em um projeto react native no windows 10? Passei a tarde inteira pesquisando e testando mas não consegui renderizar nem um icon. O FonteAwsome funciona mas ionicicon não consegui.

dependencia do package.json:

"dependencies": {"react": "16.9.0","react-native": "0.61.5","react-native-ionicons": "^5.0.0-rc","styled-components": "^5.0.1"}

Link install npm:

npm install react-native-ionicons

Utilizo React-native > 0.6, então não preciso linkar mais.Segui o código:

import React, { Component } from 'react';import { View, Text, StyleSheet } from 'react-native';import Icon from 'react-native-ionicons';class MyClass extends Component {  render() {    return (<View style={styles.container}><Text>MyClass</Text><Icon ios="ios-add" android="md-add" /></View>    );  }}const styles = StyleSheet.create({  container: {    flex: 1,    justifyContent: 'center',    alignItems: 'center',    backgroundColor: '#ccc',  },});export default MyClass;

Segui os passos desse tutorial mas não resolveu, nele mostra como usar no windows mas não entendi também o guia, se alguém poder me ajudar agradeço.enter link description here

How to enable option "set as wallpaper" ? I'm using expo and I'm not able to find any API to enable that functionality.I only able to download image. I want to trigger set as wallpaper option.I tried to use react-native-wallpaper-manager library but it has not worked for me.

I developed an application that through some requests by AXIOS to certain apis it presents data, the app is very simple, I have checked all links and they all start with HTTP or HTTPS .. The application works perfectly if I generate the apk in DEBUG mode , but if I create an apk release the error comes ...

it is worth mentioning that this is a project ejected from the expo

this is the logcat log when i open the app release:

I've read pretty much read every article from google search, watched all the YouTube tutorials and checked out all the StackOverflow questions relating to this but cannot find my answer.

The official (but outdated) docs is not all that useful at all.

My git bash just keeps showing

And if I try to type in android.bat, it returns

The "android" command is deprecated.

For command-line tools, use tools\bin\sdkmanager.bat

And then if I try to type in sdkmanager.bat, I get

I found out about the official SDK Manager installer made by Google Inc. and now my folder C:\Users\RickyDam\AppData\Local\Android\android-sdk looks like this

But I still get

It is almost like it cannot find the files found in the Android res directory such as strings.xml

Am I missing some setting in the app/build.gradle file that is causing the build process to fail in this fashion?

I'm trying to run an app inside my Android emulator and on my Iphone using Expo and Create React Native App.

I' ve ran the following commands to do this.

create-react-native-app MyFirstAppnpm run android

After doing the run command the app runs in the emulator with the following error:

Something went wrong! Could not load *ip*. Network response timed out.Uncaught error: java.net.SocketTimeoutException: connect timed out.

The same thing happens when I scan the QR code on my Iphone and I can't reach the ip in my web browser.

I've found the following fixes on internet but nothing seems to work:

• Add port 19000 to the inbound rules in Windows Firewall
• Update Java and npm
• npm start instead of npm run android

Edit:

I installed Expo XDE to start the server. It works fine when I use a tunnel but that option is extremely slow when reloading changes. It still doesn't work with localhost or LAN. Is it possible that I have to use something like port forwarding to open this port on my router?

Also: When I typ: localhost:19000 in Google Chrome I get some Json returned. But this doesn't work when I'm in Expo!

I am trying to update the react native app in the app store I am getting the error with it.

I want to run react native app on Android simulator. When I run expo start, Metro Builder opens on the chrome (http://localhost:19002/), Then I click on the Run on Android device/emulator. App installs on the simulator but Expo app gets this error:I think this is for ports. How can I solve this error? I upgrade react native and do many issues from StackOverflow. but problem not solve.

I am new to react native trying to save data to mogo db database I am getting the warning but my data is inserted in database.

My Code is as follows:

fetch("http://8ae1999e.ngrok.io/send-data", {            method: "post",            headers: {'Content-Type': 'application/json',            },            body: JSON.stringify({                name,                email,                phone,                picture,                salary,                position            })        }).then(res => res.json())            .then(data => {                console.log(data)                Alert.alert(`${data.name} is saved.`)                navigation.navigate("Home");            })

But it gives me warning

while posing data and can't navigate to Home Screen as well.

I'm a new in react native so first thing I made is to install react native by running npm install -g react-native-cliand after running react-native infoI get this

the error as showing in the log Is about the adb but I can use the adb command to install and get logcat in both the emulator and the real devices without any error

the code that I run is the default one that is created by react nativealso the app is installed successfully on my emulator but when I run it I get an error tells me the app will stophow I can solve this issue ?

I currently have a react native app with one main screen that navigates to a second screen that has 3 text inputs. The problem I am having only occurs on Android. On the second screen, whenever a text input is in focus and I try to navigate back via react navigations’ back button, the keyboard hides, then reappears, then hides, and then transitions back to the first screen. It seems when I initially press the back button the inputs focus is blurred, then when I let go it refocuses on the input and then blurs it again and then navigates back. Not sure why this is happening on Android. It works as expected on iOS. Any solutions?

Thanks!

In my scenario, I am trying to create a validation logic within render return. I have asycstorage value I am getting value and validate by using below code

render() {    const value = AsyncStorage.getItem(‘username’);  return ({value !== null &&        (<View……………..</View> )})}

Above code not validating also based on validation result it is not rendering. If value not equal to null mean, I need to render view. How to achieve this?

So I have the following lifecycle component. It will not compile as apparently I need a semicolon right after the '()'. This makes no sense at all to me. I have never seen it that way before

  componentDidMount() {    navigator.geolocation.getCurrentPosition(      position => {        this.fetchWeather(position.coords.latitude, position.coords.longitude);      },    );  }}```eslint is giving me an error where ```componentDidMount``` is being called as I need a semicolon. Huh? Can anyone see why this would be? I have not seen it called with a semicolon like this componentDidMount();  When I put in the semicolon then I get an error saying **ReferenceError: Can't find variable componentDidMount**. This is very confusing to me. I left out the state definition to make this more readable and shorter code to look at too.This is a react-native mobile weather application that I am building for a personal project.

How does one debug their React code with React Native while the app is running in app simulator?

I've installed react-native-cli globally:

npm install -g react-native-cli

Then run:

react-native init AwesomeProjectcd AwesomeProject

I got the following structure:

-- AwesomeProject   ---- node_modules      ------ react-native    

When I run react-native run-android I get an error:
Command run-android unrecognized. Did you mean to run this inside a react-native project?

When I run react-native start I get the same.

react-native -v
prints:
react-native-cli: 0.2.0
react-native: n/a - not inside a React Native project directory

What I'm doing wrong?
