I got this problem when i expo publish my react native app with or without --release-channel dev flag.I set up a config file environment.js to get different release version like this :

import Constants from "expo-constants";import { Platform } from "react-native";const localhost = Platform.OS === "ios" ? "localhost:8080" : "10.0.2.2:8080";const ENV = {  localhost: {    //apiUrl: localhost,    apiUrl: "http:xxxx",  },  dev: {    apiUrl: "http:xxxx",  },  staging: {    apiUrl: "http:xxxx",    // Add other keys you want here  },  prod: {    apiUrl: "http:xxxx",    // Add other keys you want here  },};const getEnvVars = (env = Constants.manifest.releaseChannel) => {  // What is __DEV__ ?  // This variable is set to true when react-native is running in Dev mode.  // __DEV__ is true when run locally, but false when published.  if (__DEV__ || env === undefined || env === null || env === "") {    return ENV.localhost;  } else if (env.indexOf("dev") !== -1) {    return ENV.dev;  } else if (env.indexOf("staging") !== -1) {    return ENV.staging;  } else if (env.indexOf("prod") !== -1) {    return ENV.prod;  }};export default getEnvVars;

I intercept the config with creation of new intance of axios like this :

import axios from "axios";import { getKey } from "./deviceStorage";import getEnvVars from "../../environment";const { apiUrl } = getEnvVars();const instance = axios.create({  // .. where we make our configurations  baseURL: apiUrl,});instance.interceptors.request.use((config) => {  const token = getKey("id_token");  token.then((value) => {    config.headers.Authorization = value ? `Bearer ${value}` : "";  });  return config;});export default instance;

when i emulate on my device every thing work fine but when i expo publish and scan QR code with my device the app crash after splash screen and i got this error say :

Please any help thanks !!!

I'm using React Native at work on the latest macOS version, allowing me to easily use Simulator for testing and debugging on iOS.

Now I want to debug and test on Android. I have a personal Android device, but it's hard for me to get the app working on it using Expo (don't have a physical cable on me atm, and security at work makes it hard for tunneling service to work over the same network with our staging build).

I'm trying to get an Android emulator running on macOS. I personally hate Android Studio and would rather not use it. I know that there's sdkmanager and the Android Command Line tools that Microsoft provides, but I'm not sure how to get started using with those. I'd be using Genymotion if it was free, but it isn't unfortunately.

What do other React Native developers who test and debug on Android do?

Thanks!

Trying to run the react native app on mobile device connected using react-native run-android. The app build was successful but the app crash on opening and on the command prompt it stucks on Starting: Intent { cpm=com.project.projectname/.MainActivity }

The App installed on the mobile device but always keep stopping. Can someone help me how to debug this and i cant see where the error messages at.

this the whole command prompt output

I'm using react-native-firebase v6.4.0. I successfully registered a background handler with setBackgroundMessageHandler and everything works fine. Now I'm trying to handle notification tap when the app is in background/quit and I'm using onNotificationOpenedApp/getInitialNotification. The problem I'm facing is that the first method is never triggered while the second is triggered but remoteMessage parameter is always null. I've also tried to generate a release build but the result is the same.

index.js

// importsmessaging().setBackgroundMessageHandler(async remoteMessage => {  // storing the message with redux});function HeadlessCheck({isHeadless}) {  return isHeadless ? null : <App />;}AppRegistry.registerComponent(appName, () => HeadlessCheck);

App.js

// other importsimport messaging from '@react-native-firebase/messaging';import {store, persistor} from './Store';export default function App() {  useEffect(() => {    (async () => await messaging().registerDeviceForRemoteMessages())();    const unsubscribe = messaging().onMessage(async remoteMessage => {      store.dispatch(storeNews(remoteMessage));    });    messaging().onNotificationOpenedApp(remoteMessage => {      // The below code gets never executed      Alert.alert('here');      console.log('Notification caused app to open from background state:',        remoteMessage,      );    });    messaging()      .getInitialNotification()      .then(remoteMessage => {        console.log(remoteMessage); // always prints null        if (remoteMessage) {          // Never reached          Alert.alert('here');          console.log('Notification caused app to open from quit state:',            remoteMessage,          );        }      });    return unsubscribe;  }, []);  return (<><StatusBar barStyle="dark-content" /><Provider store={store}><PersistGate loading={null} persistor={persistor}><RootNavigator /></PersistGate></Provider></>  );}

I am getting these errors.

TypeError:undefined is not an object (evaluating'_reactnative.View.propTypes.style')

Environment

• Environment:

  • OS: macOS High Sierra 10.13.1
  • Node: 8.9.1
  • Yarn: 0.17.10
  • npm: 5.6.0
  • Watchman: 4.7.0
  • Xcode: Xcode 9.2 Build version 9C40b
  • Android Studio: 2.3 AI-162.4069837

• Packages: (installed)

  • react: 16.0.0
  • react-native: 0.51.0

Steps to Reproduce

Run this code

import React, {Component} from 'react';import {View, Text, TouchableOpacity} from 'react-native';class App extends Component {  render() {    return (<View style={styles.container}><View><TouchableOpacity style={[styles.boxShadow, shadow]}><Text style={styles.text}>LOGIN</Text></TouchableOpacity></View></View>);  }}const shadow = {  shadowColor: '#30C1DD',  shadowRadius: 10,  shadowOpacity: 0.6,  elevation: 8,  shadowOffset: {    width: 0,    height: 4  }}const styles = {  container: {    flex: 1,    justifyContent: 'center',    alignItems: 'center'  },  boxShadow: {    width: 200,    height: 50,    borderRadius: 10,    backgroundColor: '#ed7171',    justifyContent: 'center',    alignItems: 'center'  },  text: {    color: '#ffffff'  }};export default App;

Expected Behavior

Is there way to achieve like this Shadow in Android

as shadow Props of react-native only supports in iOS

• color need to be changed
• Tried elevation but can not change default greyed color
• able to achieve in ios with shadowColor props but not in android as it is only support iOS

Actual Behavior

See sample code and preview.

• It should be work for android too.
• Shadow color is always grey, however I tried to change..

Reproducible Demo

This is sample snapshot in which I can only get shadow with elevation with only grey color [default].

I am using ViroARSampleApp code to demonstrates placing, rotating and dragging objects in AR. Everything is working fine when I run react-native run-android --variant=arDebug but when I detach data cable and run the app then the application is running fine but objects are not rendered.

I tried to make proper APK file and install to the device but facing the same issue. I tried these commands to make build react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res/, cd android, ./gradlew assemblearDebug. i also tried ./gradlew bundlearDebugJsAndAssets.

I am new in react native and AR, kindly suggest me the solution for this issue.

I wanted to implement my own font (from google) to use it inside my app. I loaded it and it works because some text gets changed by it. However some text doenst change which doesnt make sense to me.

I guess its a bug somehow maybe somebody has experienced this. Its a simple screen with simple code.

import React, {Component} from 'react';import {View, Text, StyleSheet, Button} from 'react-native';import COLORS from '../assets/COLORS';import {TextInput} from 'react-native-gesture-handler';class BMI extends Component {  render() {const BMI = 20;    return (<View style={styles.container}><Text style={styles.textStyle}> BMI - Calculator </Text><Text style={{color: COLORS.white, fontSize: 20}} >Dein momentaner BMI:  <Text style={{color: COLORS.primary, fontSize: 24}} >{BMI}</Text> </Text><View><View style={styles.InputContainer}><Text style={styles.inputText}>AGE</Text><TextInput style={styles.TextInput} /></View><View style={styles.InputContainer}><Text style={styles.inputText}>HEIGHT</Text><TextInput style={styles.TextInput} /></View><View style={styles.InputContainer}><Text style={styles.inputText}>WEIGHT</Text><TextInput style={styles.TextInput} /></View><View style={{marginTop: 25, marginHorizontal: 15}}><Button onPress={() => alert("Hello")} title="Calculate" color={COLORS.lightB} /></View></View></View>    );  }}const styles = StyleSheet.create({  container: {    flex: 1,    alignItems: 'center',    // justifyContent: "center",    backgroundColor: COLORS.darkBG,  },  textStyle: {    color: COLORS.lightB,    fontSize: 30,    fontWeight: 'bold',    marginVertical: 30,    fontFamily: "Pacifico"  },  InputContainer: {    justifyContent: 'space-around',    flexDirection: 'row',    width: '100%',    marginVertical: 20,  },  inputText: {    color: COLORS.white,    width: '30%',    marginLeft: 15,    fontSize: 18,    fontFamily: "Pacifico"  },  TextInput: {    backgroundColor: COLORS.primary,    width: '60%',    color: COLORS.white,    fontFamily: "Pacifico"  },});export default BMI;

As u can see I load pacifico and it works but only for this text ( see pic below ):

I'm writing a React Native app that uses the react-navigation 5.x library, specifically @react-navigation/drawer. I have four screens in the drawer, each with an icon and a label.

Screenshot

My problem is that the labels for each screen do not line up correctly -- see the 'Device Configuration' item compared to the others. The alignment seems to depend on the size of the icon, with the wider icons pushing the label more to the right.

I've tried hard-coding the size of the icon so that they're all the same, but that didn't work. I'm not sure what else to try. I'd appreciate any ideas!

My code:

function Icon(props) {    return (<Ionicon            name={props.name}            size={props.size}            color={props.color}        />    );}const DrawerNavigator = createDrawerNavigator();function Drawer() {    return (<DrawerNavigator.Navigator            drawerContentOptions={{                activeTintColor: Colors.drawerScreenSelected            }}><DrawerNavigator.Screen                name="Home"                component={Tabs}                options={{                    drawerIcon: ({color, size}) => (<Icon name="md-home" color={color} size={size} />                    )                }}            /><DrawerNavigator.Screen                name="Login"                component={LoginScreen}                options={{                    drawerIcon: ({color, size}) => (<Icon name="md-log-in" color={color} size={size} />                    )                }}            /><DrawerNavigator.Screen                name="Device Configuration"                component={DeviceConfigScreen}                options={{                    drawerIcon: ({color, size}) => (<Icon name="md-bluetooth" color={color} size={size} />                    )                }}            /><DrawerNavigator.Screen                name="Email Data"                component={ExportDataScreen}                options={{                    drawerIcon: ({color, size}) => (<Icon name="md-at" color={color} size={size} />                    )                }}            /></DrawerNavigator.Navigator>    );}export default Drawer;

I'm creating an app in React Native in which I want to download a video in the application, but that video should not appear in Gallary of the device. It should download in the application's folder. How should I do that any idea?

I am currently working on a react-native application.I would like to use the camera with the 'expo' package.

I manage to display the camera, but when I switch between my components (main menu component/ settings component) and I return to the camera component, the camera preview is black.

In fact it is the same problem as here: https://github.com/expo/expo/issues/5952

I used the proposed solution but it still doesn't work.

import React, { useState, useEffect } from 'react';import { Text, View, TouchableOpacity, Dimensions } from 'react-native';import { Camera } from 'expo-camera';import { useFocusEffect, useNavigation } from '@react-navigation/native';import { FontAwesome, Ionicons,MaterialCommunityIcons } from '@expo/vector-icons';import { withNavigationFocus } from 'react-navigation';import * as Permissions from 'expo-permissions'import styles from './styles';class CameraPage extends React.Component {  camera = null;  state = {      hasCameraPermission: null,  };  async componentDidMount() {      const camera = await Permissions.askAsync(Permissions.CAMERA);      const hasCameraPermission = (camera.status === 'granted');      this.setState({ hasCameraPermission });  };  render() {      const { hasCameraPermission } = this.state;      if (hasCameraPermission === null) {          return <View />;      } else if (hasCameraPermission === false) {          return <Text>Access to camera has been denied.</Text>;      }      else if (this.props.isFocused)      {        return (<View style={{ flex: 1 }}><Camera style={{ flex: 1 }} type={this.state.cameraType}></Camera><Text> IS FOCUS </Text></View>        )      }  };};export default withNavigationFocus(CameraPage);

The app launches by default in the camera component and the camera preview is displayedAs I have said, when I switch the component and come back to the camera the preview stays black,but the text 'IS FOCUS' is displayed so this.props.isFocused is true.

Therefore the problem comes from the camera itself. But I do not understand.

Any ideas where the problem comes from?

I am using following code to render a webview:

const someHTMLFile = require('./somefile.html')render() {  return (<View style={{flex: 1}}><WebView          style={{flex: 1}}          source={someHTMLFile}          ref={( webView ) => this.webView = webView}      />      </View>  );}

In this html file, there is a form which is automatically submitted when the webview loads (with some data sent from reactnative part of code) and in the end, the file is redirected to a specific url, where some processing is done (on the send data), and right now, it returns nothing. So the screen goes blank.

So, at this point, I want to close the webview and take the user back to my reactnative app.. So, how can I do that? any suggestions?

I have a @react-navigation/bottom-tabs navigator when my app opens whose contents are like:

<Tab.Navigator        tabBarOptions={{            activeTintColor: '#77dd77',            inactiveTintColor: 'gray',        }}        tabBar={props => <MyTabBar {...props} />}        backBehavior={"history"}><Tab.Screen            name="Home"            component={Home}            options={{ title: 'Home' }}        /><Tab.Screen            name="Orders"            component={Orders}            options={{ title: 'Orders' }}        /><Tab.Screen            name="Profile"            component={Profile}            options={{ title: 'Profile' }}        /></Tab.Navigator>

I have a BackHandler in my code that makes the app exit when back button is pressed from the home page. Everything is fine and I have checked that the backhandler gets called when back button is pressed.

But when I switch to any other tab and then return to the homepage and press back to exit the app, backhandler stops working and the app shows error "The action 'GO_BACK'was not handled by any navigator. Is there any screen to go back to?"

This is a development-only warning but in the signed version, the app doesn't show any error and doesn't even exit.

How can I address this 'GO_BACK' action?

I'm trying to debug my project and to deploy it as APK.I'm using only android. When I debug the project or install the signed release APK it crashes.Now I search the error with ./gradlew build --stacktrace

What I've tried:- jetify- dependencies: implementation(:react-native-screens)and many things more, but I can't tell it all.

It's blocking my work.

The exception for ./gradlew build --stacktrace is:

I want to set my tabBar of borderRadius 30 and set the backgroundColor of the tabBar, but the problem is that there is white color background in the tabBar even if I have set the backgroundColor to other color! How to resolve this?

tabBarOptions: {  showIcon: true,  showLabel: false,  activeTintColor: '#333645',  inactiveTintColor: 'grey',  style: {    backgroundColor: '#FEB6B9',    height: 50,    borderRadius: 30,    marginBottom: 10  }}

I can't set the color of the status bar on iOS and Android on React Native with Expo.I just managed to hide it.

Code :

import * as React from 'react';import { WebView } from 'react-native-webview';import { StatusBar } from 'react-native'export default class App extends React.Component {   render() {      return <><StatusBar hidden={true} /><WebView source={{ uri: 'https://foo.co' }} style={{ marginTop: 33 }} /></>   }}

I already tried :

<StatusBar hidden={false} barStyle="light-content" />

and :

<StatusBar barStyle = "dark-content" hidden = {true} backgroundColor = "#00BCD4" translucent = {true}/>

I am really confused about how this StatusBar works.

Thank you in advance!

It also happens with typescript template

I am using this library in RN to implement fingerprint scanning react-native-fingerprint-scanner and its working fine with scanning but I would like to implement a function that registers a new fingerprint for this app. I was absolutely not able to find it anything on the internet related to this.

Here is the code that I have implemented so far:

import React, { Component } from 'react';import {    Alert,    Image,    Text,    TouchableOpacity,    View,    ViewPropTypes} from 'react-native';import FingerprintScanner from 'react-native-fingerprint-scanner';import PropTypes from 'prop-types';import ShakingText from './ShakingText.component';import styles from './FingerprintPopup.component.styles';class FingerprintPopup extends Component {    constructor(props) {        super(props);        this.state = { errorMessage: undefined };    }    componentDidMount() {        FingerprintScanner            .authenticate({ onAttempt: this.handleAuthenticationAttempted })            .then(() => {                this.props.handlePopupDismissed();                Alert.alert('Fingerprint Authentication', 'Authenticated successfully');            })            .catch((error) => {                this.setState({ errorMessage: error.message });                this.description.shake();            });    }    componentWillUnmount() {        FingerprintScanner.release();    }    handleAuthenticationAttempted = (error) => {        this.setState({ errorMessage: error.message });        this.description.shake();    };    render() {        const { errorMessage } = this.state;        const { style, handlePopupDismissed } = this.props;        return (<View style={styles.container}><View style={[styles.contentContainer, style]}><Image                        style={styles.logo}                        source={require('../pictures/finger_print.png')}                    /><Text style={styles.heading}>                        Fingerprint{'\n'}Authentication</Text><ShakingText                        ref={(instance) => { this.description = instance; }}                        style={styles.description(!!errorMessage)}>                        {errorMessage || 'Scan your fingerprint on the\ndevice scanner to continue'}</ShakingText><TouchableOpacity                        style={styles.buttonContainer}                        onPress={handlePopupDismissed}><Text style={styles.buttonText}>                            BACK TO MAIN</Text></TouchableOpacity></View></View>        );    }}FingerprintPopup.propTypes = {    style: ViewPropTypes.style,    handlePopupDismissed: PropTypes.func.isRequired,};export default FingerprintPopup;

EDIT: Or at least I would like to prompt the user to set Fingerprint if they already don't have any finger enrolled in the phone.
