I have a App component which is:

import Home from './screens/Home';import * as React from 'react';const App = () => {  return <Home />;};export default App;

My home component looks like:

  export default class Home extends React.PureComponent {  render() {    return (<><View style={styles.container}><Text style={styles.heading}> Location Manager </Text><CurrentLocation /><LocationList /></View><ClearButton /></>    );  }}

I wrote a component that watches for location changes:it looks like:

export const useGeolocation = (): [string, GeolocationData] => {  const [error, setError] = useState('');  const [position, setPosition] = useState<GeolocationData>({    latitude: 0,    longitude: 0,  });  useEffect(() => {    const watchId = Geolocation.watchPosition(      (pos) => {        setError('');        setPosition({          latitude: pos.coords.latitude,          longitude: pos.coords.longitude,        });      },      (e) => setError(e.message),    );    return () => Geolocation.clearWatch(watchId);  }, []);  return [error, position];};

Now how do I use this component? where do I place this? I read it on a tutorial that it will unsubscribe when user is not using the app (backgrounded) or component will unmount? How to achieve that?

I integrated React Native into an existing Android project. The code compiles fine, but when I get to the part of my app that initializes React Native, the app crashes.

Relevant part of the backtrace:

java.lang.RuntimeException: Requested enabled DevSupportManager, but DevSupportManagerImpl class was not found or could not be created      Caused by: java.lang.RuntimeException: Requested enabled DevSupportManager, but DevSupportManagerImpl class was not found or could not be created        at com.facebook.react.devsupport.DevSupportManagerFactory.create(DevSupportManagerFactory.java:77)      Caused by: java.lang.reflect.InvocationTargetException        at java.lang.reflect.Constructor.newInstance(Native Method)        at com.facebook.react.devsupport.DevSupportManagerFactory.create(DevSupportManagerFactory.java:70)      Caused by: java.lang.NoClassDefFoundError: com.facebook.react.bridge.JSPackagerWebSocketClient        at com.facebook.react.devsupport.DevServerHelper.<init>(DevServerHelper.java:108)        at com.facebook.react.devsupport.DevSupportManagerImpl.<init>(DevSupportManagerImpl.java:141)

The key part is

java.lang.NoClassDefFoundError: com.facebook.react.bridge.JSPackagerWebSocketClient.

I'm not sure why this class wouldn't be found. The location where this crash happens in the React Native source code is here.

UPDATE: If it's relevant, I was getting compile-time errors before this that I fixed with the solution here (which excludes okhttp-ws) which I wonder may be causing this.

UPDATE 2: I'm starting to think this is related to excluding okhttp-ws since I noticed in JSPackagerWebSocketClient.java there are imports such as:

import okhttp3.ws.WebSocket;

So I guess the real question is what is the real fix for the original issue I was having, which is:

com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: okhttp3/internal/ws/RealWebSocket$1.class

I'm using React Native v0.31.0.

I'm trying to use the exoplayer for my React Native app using the React Native video package.

I have an app with both a HLS stream and a mp4 videos, these videos and are stored on my server (https).

When browsing through videos the player gets stuck in an infinite buffer state and stays that way until I restart the app. This is completely random. The only way to reproduce the problem is just watching videos and switch the source multiple times.

When looking in the Android logcat there are no errors. adb bugreport doesn't work either.

Is someone familiar with this issue?

Soon new Huawei phones will stop supporting Google Play and Google Mobile Services.

Huawei is preparing its own ecosystem called HMS https://developer.huawei.com/consumer/en/service/hms/developer.html

Their app store is called "Huawei App Gallery" and has its documentation here: https://developer.huawei.com/consumer/en/doc/30202

They are now sending messages to developers (including me) that encourage them to release an app to their store. They are claiming that they only need an APK file and no changes to the application are needed.

My questions are:

• Is a react-native app going to work without code changes?
• Is Firebase SDK going to work?
• What is the real hidden cost of maintaining an app in another Android ecosystem?

I am getting an error saying unable to instantiate activity. This activity is a module ModuleX which is inside the main project and also it's enabled for dynamic feature.

Also, I have recently added one another library TwilioRN on the main project ProjectX. Both ModuleX and TwilioRN has the same dependencies using same version.

ProjectX - build.gradle    - implementation project(':react-native-twilio-video-webrtc')        - dependencies             - implementation 'com.twilio:video-android:5.6.0' - ModuleX (dynamic feature)    - build.gradle       - implementation 'com.twilio:video-android:5.6.0'

Actual Behaviour:

• when I removed TwilioRN from main project, com.projectX/com.moduleX.videocall.VideoActivity activity started successfully and it worked.
• But when twilioRN are present, VideoActivity activity is not called and getting crashed.

Expected Behaviour:

Hi I'm using react native, so I needed exoplayer to show subtitle on it in android....I added exoplayer inside my app, after that should I do something to use exoplayer as default or it will link to react-native-video ?thanks

I'm using the Expo Admob library as part of my React Native app.

https://docs.expo.io/versions/latest/sdk/admob/

The Rewarded Admob Ad feature that works perfectly with a Test Admob Unit Id fails when using my production Admob Unit Id.

This works great! The ad loads.

await AdMobRewarded.setAdUnitID('ca-app-pub-3940256099942544/5224354917'); // Test ID, Replace with your-admob-unit-idawait AdMobRewarded.requestAdAsync();await AdMobRewarded.showAdAsync();

If I replace setAdUnitID(...) with my production key, the ad does not load instead throws the following error. I am running this using the Expo client so I can capture the error message however I am still getting an error when running it in production (eg. installing the apk).

I'm using

Expo: 37.0.3expo-ads-admob: 8.1.0react: 16.9.0react-native: 0.61.4

Is there something here that I have missed?

I am trying to open URL in a specific browser using package name in Android. I am using Expo's WebBrowser.openBrowserAsync()

Per documentation, you can pass the browser package name.

https://docs.expo.io/versions/v37.0.0/sdk/webbrowser/#webbrowseropenbrowserasyncurl

package (optional) (string) -- (Android only). Package name of a browser to be used to handle Custom Tabs

So, I tried using the code below, but its showing a browser selection dialog. How can I open it automatically in Chrome without prompting for the browser selection dialog?

WebBrowser.openBrowserAsync('https://google.com', { package: 'com.android.chrome' });

After running npx react-native run-android i got the common issue "Task 'installDebug' not found in project ':app".'

Following an advice i tried to do this https://reactnative.dev/docs/signed-apk-android, but when i run:$ ./gradlew bundleRelease from android directory i got: "Task 'bundleRelease' not found in root project 'MoscowForDummies'."

My gradle.properties:

MYAPP_UPLOAD_STORE_FILE=my-upload-key.keystoreMYAPP_UPLOAD_KEY_ALIAS=my-key-aliasMYAPP_UPLOAD_STORE_PASSWORD=Profit***MYAPP_UPLOAD_KEY_PASSWORD=Profit***

Part of my build.gradle:

android {compileSdkVersion rootProject.ext.compileSdkVersioncompileOptions {    sourceCompatibility JavaVersion.VERSION_1_8    targetCompatibility JavaVersion.VERSION_1_8}defaultConfig {    applicationId "com.moscowfordummies"    minSdkVersion rootProject.ext.minSdkVersion    targetSdkVersion rootProject.ext.targetSdkVersion    versionCode 1    versionName "1.0"}signingConfigs {    release {        if (project.hasProperty('MYAPP_UPLOAD_STORE_FILE')) {            storeFile file(MYAPP_UPLOAD_STORE_FILE)            storePassword MYAPP_UPLOAD_STORE_PASSWORD            keyAlias MYAPP_UPLOAD_KEY_ALIAS            keyPassword MYAPP_UPLOAD_KEY_PASSWORD        }    }}

and my ~/.bash_profile:

export ANDROID_HOME=$HOME/Android/Sdkexport PATH=$PATH:$ANDROID_HOME/emulatorexport PATH=$PATH:$ANDROID_HOME/toolsexport PATH=$PATH:$ANDROID_HOME/tools/binexport PATH=$PATH:$ANDROID_HOME/platform-tools

Does anybody have any advice how to fix the problem?

I have a react.js web app I need to convert to the mobile app, Is there any way to do that? I have tried to search for a solution but I did not find anything that can helpThanks.

For a project, I have to indicate, with colored arrows, in which direction are the markers that aren't shown in the visible region.

When the user scrolls, or zoom on the map, the arrows move accordingly to where the not visible markers are compared to the current center of the visible region.

Here is a picture that demonstrate what is needed :

I am using react-native-mapview and added regular views over the map to show the indicators.

I've started working on this by comparing the coordinates and calculating the point of intersection between lines (border lines and line made by the 2 coordinates) at each frame. It works fine on iOS but is pretty laggy on Android, especially chan there are a lot of markers involved.

What would be the best and optimized way to do this ?

I've a problem with deeplink on iOS. Here is the case : I've a web page with a classic button using an universal link such as https://my-app/routeA/params.

If the user directly clicked on this link through mail, note, message the deeplink to my mobile app is working. However, if he clicked with the button (on the web page), through safari or chrome, the deeplink doesn't work.

By the way, the deeplink works well on Android when the user click on the button (within the web page).

So it seems to be a problem with web navigator on iOS. Any ideas what's wrong here ?

Is it possible to load "sub-apps" inside a mobile application? The way like Expo client does that - you start a "parent" app and inside that you dynamically load other apps.

Requirements:

• Parent app downloadable from the store.
• Sub-apps not published in the store
• Sub-apps always up to date - possibility to update them independently on the parent app.
• Android and iOS compatible

I am not able to inject this simple js code into react-native webview.

I referred this link also but no solution provided here.

Then I found this one which works for html props but not uri.

import React, { Component } from 'react';import { Platform,  StyleSheet,  Text,  View,  WebView} from 'react-native';export default class App extends Component<{}> {  injectjs(){    let jsCode = 'alert(hello)';    return jsCode;  }  render() {    return <WebView     javaScriptEnabled={true}    injectedJavaScript={this.injectjs()}     source={{uri:"https://www.google.com"}} style={{ marginTop: 20 }} />;  }}

I'm using react-native-best-viewpager to make a easy viewpager without too many work on some graphics stuff, but i'm in need of using nested viewpagers (One inside other), like the code below, but the problem it's that the second viewpager dont scroll, only the first one. If this was a Scrollview i would use nestedScrollEnabled={true}, but this is a viewpager:

import React, { Component } from 'react'import {IndicatorViewPager, PagerTabIndicator, PagerDotIndicator } from 'react-native-best-viewpager'import { View } from 'react-native'class MainScreen extends Component {    _renderTabIndicator() {        let tabs = [            {                text: 'Screen'            }]        return <PagerTabIndicator tabs={tabs} />    }    _renderDotIndicator() {        return <PagerDotIndicator pageCount={1} />    }    render() {        return (<View style={{flex: 1}}><IndicatorViewPager style={{height: 500}} initialPage={1} indicator={this._renderTabIndicator()}><View style={{flex: 1}}><IndicatorViewPager style={{height: 300}} indicator={this._renderDotIndicator()}><View style={{flex: 1}}><View style={{BackgroundColor: 'black', height: 50, width: 50}}/></View></IndicatorViewPager></View></IndicatorViewPager></View>        )    }}export default MainViewport;

(Just a example code)

Thanks in advance!

I have trying to figure out this few days, but no luck.

Please, any helps would be very appreciated.

I am developing react native app I am trying to use firebase authentication with otp code from sms and it is work with ios, but not with android. In android I have such errorI try to solve this issue like it is described hereI ran ./gradlew signingReport from android folder and found that I have error Error: Missing keystoreDoes anyone know how to solve this? Thanks!

I'm trying out react native and ejected into a full build environment. Sadly, the eject-script did not create a sensible .gitignore file.

Not knowing a lot about app-development, I wonder what directories I could .gitignore here?

I'm guessing:

• android/build
• android/app/build
• android/.gradle/

Are these alright, or are there any more directories I should .gitignore?

I am a beginner in react-native. When I am running the command react-native run-android, the Node.js window opens for a while and then closes immediately. Please do help me.

According to RN docs this should be impossible but I'm getting a red screen error on my app downloaded from the playstore. The playstore version generally works fine but there was a null value on one of the screens and it popped a redscreen.

Definitely uploaded the release version of APK using Build --> Generate Signed Bundle/APK. I'm totally at a loss of where else to look as I can't find any mentions of similar situations through searches.

Build.gradle file looks like:

 buildTypes {        release {            minifyEnabled enableProguardInReleaseBuilds                signingConfig signingConfigs.release            proguardFiles getDefaultProguardFile("proguard-android.txt"), "proguard-rules.pro"        }        debug {    debuggable false}

Edit for additional steps I've tried:

Tried following this RN guide for releasing as well: https://reactnative.dev/docs/signed-apk-android to no avail.

Confirmed the apk I'm using is in-fact a release build using jarsigner -verify -verbose -certs my_application.apk

Testing using a console.error() just after I see the app load successfully and that consistently shows a red screen.
