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 am trying to set up an existing react native project. I have got a zip file with project and want to make it run with android emulator from android studio.

For this I run npm install, then npx react-native run-android (while running the android emulator). After that I keep getting an error

Could not find or load main class org.gradle.wrapper.GradleWrapperMain

. I have already tried all possible solutions I could find here and everywhere like running gradle wrapper etc.

After deleting the gradle folder and setting it up again (with gradle wrapper) I've got different error message

React native: Android project not found. Maybe run react-native android first?

So I run react-native upgrade clicked -y to all options ( like shown here. After that I got the same error again

Could not find or load main class org.gradle.wrapper.GradleWrapperMain

I followed the steps of the installation tutorial toolbarAndoid and the implementation tutorial expo, but when running on the android application the following stack appears:

Now, when I am using the APK in android 5.0, everytime my app crashes it open up a small window at bottom to share the report via email. The image bellow shows the share option popping up in Android 5.0, Phone is Sony Xperia E2362.

But when I am using the APK in Android 10, phone xiaomi poco f1. It doesn't show me any window to share the file.But right after I install my app, xiaomi scans the app and gives one option to open it. And when I open the app from that window I get that share report via email popup, after the app crashes.But not when I normally open my app from app menu.Bellow image shows the app scanning window which shows an option to open app and the second image which shows the share report via email when I use scanning window to open app.

I don't know what am I missing. Please help.

I have tried all of the examples out there but I can not figure it out. I am using this https://github.com/xinthink/react-native-material-kit

I am using stack navigation and drawer navigation for some screens. I have created customized status bar with background color white and dark content. However it is working with the stack navigation routes but not with drawer navigation routes. Blue status bar is showing in drawer navigation routes as below:

My Routes.js (Where I used stack navigation)

....import { createStackNavigator, HeaderBackButton } from 'react-navigation-stack';import { Drawer } from '../components/Drawer';const RootStack = createStackNavigator(    {        Drawer: {             screen: Drawer        },         // other screens     },    {        initialRouteName: 'InitialScreen',        headerMode: "none",    })const App = createAppContainer(RootStack);export default App;

My Drawer.js (Where is use Drawer Navigation and blue bar is not changing)

.....import { createDrawerNavigator } from 'react-navigation-drawer';import ProductScreen from '../screens/ProductScreen';export const Drawer = createDrawerNavigator(    {        Product: { screen: ProductScreen }    },    {        navigationOptions: () => ({            drawerLockMode: 'locked-closed',        }),        initialRouteName: "Product",        drawerPosition: 'left',        headerMode: 'none'    });

How to change this blue bar on drawer navigation ?

I a, developing an application using react Native version 0.59.10 an react-native-navigation version 1.1.493. I used MobX for state management.

Currently i am trying to integrate a native SDK that tracks the user driving sessions.

Before the SDK can be initialized the asks the user for location permissions.

Once the SDK is initialized it broadcast an event to the JS layer using the following code:

fun notifyJS(  context: Context?,  receiver: BroadcastReceiver,  eventName: String,  data: WritableMap?) {  val reactApplication = context?.applicationContext as? ReactApplication  val instanceManager = reactApplication?.reactNativeHost?.reactInstanceManager  val reactContext = instanceManager?.currentReactContext  if (reactContext != null) {    Log.d(      LOG_TAG,"React context is available, sending event $eventName"    )    reactApplication.reactNativeHost?.reactInstanceManager?.currentReactContext?.getJSModule(      DeviceEventManagerModule.RCTDeviceEventEmitter::class.java    )?.emit(eventName, data)  } else {    Log.d(LOG_TAG, "React context is not available")    val pendingResult = receiver.goAsync()    instanceManager!!.addReactInstanceEventListener(      object : ReactInstanceManager.ReactInstanceEventListener {        override fun onReactContextInitialized(reactContext: ReactContext) {          Log.v(            LOG_TAG,"React context is initialized sending js event $eventName"          )          reactContext.getJSModule(            DeviceEventManagerModule.RCTDeviceEventEmitter::class.java          )?.emit(eventName, data)          instanceManager.removeReactInstanceEventListener(this)          pendingResult.finish()        }      })    instanceManager.createReactContextInBackground()    Log.d(LOG_TAG, "Called to create context in the background")  }}

at this point the reactContext variable is always null, even if the application is in the foreground which causes the application to restarts itself.

I have basic understanding in native development, and i search the web for hours about the case but i cant seem to understand how the context can be null when the application is in the foreground.

So i am guessing there is the possibility that maybe this code gets the wrong context...?

My application uses some other 3rd party libraries and this is the current package.json file

On my testing to figure out what causing this behavior i started removing libraries from my code, even when i only loaded the: ReactNativePackage, ReactNativeConfigPackage and the RNNPackage to issues occurs so i am pretty sre the problem comes from the use of react-native-navigation.

So i tried to create a new black application to reproduce this issue but on a brand new application (same react-native and rnn version) the issue does not reproduce. So i am guessing that over time while developing the application some configurations and patches were placed somewhere in the code.

I am having really hard time to debug and targeting what causing this issue

I want to use ComponentName in my react native module.

PackageManager pm = reactContext.getPackageManager();ComponentName cn = new ComponentName(reactContext,com.my.app.MyClass.class);pm.setComponentEnabledSetting(cn,PackageManager.COMPONENT_ENABLED_STATE_ENABLED,PackageManager.DONT_KILL_APP);

I want to use code like this.HoweverCan't get com.my.app.MyClass.class What should I do?

Is there a method that like getResources() for class?

I'm trying to detect a click on a notification.

I use react-native 0.61 and : react-native-notifications 3.1.4 (but get the same results with react-native-push-notification 3.1.9).

Everything works well but one thing: if I tap a notification or if I open my app from a notification with a notification from Firebase admin (or curl to FCM) I don't get those events fired:

Notifications.events().registerNotificationOpened

and

Notifications.getInitialNotification()

Howewer if I post a simple local notification with Notifications.postLocalNotification, everything works well.

Here is my standard curl request:

curl -X POST \  https://fcm.googleapis.com/fcm/send \  -H 'Authorization: key=mykey' \  -H 'Content-Type: application/json' \  -H 'Host: fcm.googleapis.com' \  -d '{"to" : "cgh6P5BESPesyBJwYlaSPi:APA91bEuLwxgZq4JUlo2Su-_l1DqNVoAPzC2eHQy07IQlTuUcZNRuFiLzlbiFuCsHhU74SgYbrIkY7e2v4uQbYCspzRLlDrwrfha40Ozv613xwyYPtR3lJMaTuNcNAhGh8bdrmMY4B3N","payload" : {"body" : "Body of Your Notification in Data","title": "Title of Your Notification in Title", "pushNotification": true,    }

Again, the notification appears but if I click on it, I don't get any event fired. However if I use postLocalNotification I get those events.

I have been struggling with this for days now, do I have to do something with intents in my AndroidManifest? Is there an example project with this working?

I'm working on a mobile application where at some point on registration we send user a link in email for verification. When user opens the link in the email, it verifies the user. Now the issue is it works great on web but on mobile we expect the app to be open because we have defined the intent-filter(I've attached my intent code below) but it doesn't. Basically gmail opens the link in in-App browser and if I open link explicitly on a browser the intent works fine and it opens the app but in in-App it doesn't work.

AndroidManifest.xml

<!-- for deep linking --><intent-filter android:autoVerify="true"> <action android:name="android.intent.action.MAIN"/><action android:name="android.intent.action.VIEW"/><category android:name="android.intent.category.DEFAULT"/><category android:name="android.intent.category.BROWSABLE"/><category android:name="android.intent.category.LAUNCHER"/><data android:scheme="https" android:host="*.example.net" android:path="*" /><data android:scheme="https" android:host="example.net" android:path="*" /></intent-filter>

package.json

{  ..."react-native": "0.59.10", "react-navigation": "3.9.1",  ...}

I am using react native 0.61.2. When I build the release APK, I get some text with "D8: ". I am unable to understand what does it mean.

Bellow is the loghttps://gist.github.com/ElavanResu/9cc4ce051daa1340a4531668e1bc2061

Please help me in understanding this

Everything on iOS works fine. On Android I am getting the warning "Setting a timer for a long period of time, i.e. multiple minutes, is a performance and correctness issue on Android as it keeps the timer module awake, and timers can only be called when the app is in the foreground. See https://github.com/facebook/react-native/issues/12981 for more info. (Saw setTimeout with duration 589668ms)"

I don't use any timers in my app so I am assuming this is from an NPM module I have installed. How can I determine which one is causing this?

I see that I can ignore the waring, but I would like to report the issue to the module maintainer.

I am using React Native and integrated library react-native-obfuscating-transformerto obfuscate my code. Now after decompiling my APK, I believe my whole js code is under assets/index.android.bundle.

How can I debundle it and see my code whether obfuscation worked or not.

We are looking for options to harden our app and need the following

• Obfuscation
• Jailbreak/Root detection
• Hook detection
• Swizzle detection (iOS)

What I found were:

Android - Obfuscation by proguard - Root detection using RootBeer https://github.com/scottyab/rootbeer - Hook detection ?

iOS - Obfuscation by xcode during builds - Jailbreak detection using https://github.com/TheSwiftyCoder/JailBreak-Detection - Hook detection ? - Swizzle detection?

How is hook detection done for iOS and Android.

Also for cordova/flutter apps are there any libraries for Hook detection and general app hardening in general?

I dont have any errors but I still cant open screen that I want. Here is my FlatList item:

let categories = [         {            screenName : Player,            name : "Category 1",            img : require("../Assets/Slika.jpg"),        },

Here is TouchableOpacity with onPress

return (<View style={styles.container}><FlatList                    data={categories}                    showsHorizontalScrollIndicator={false}                    numColumns={categories.length / 5}                    showsVerticalScrollIndicator={false}                    keyExtractor={(item, index) => index.toString()}                    renderItem = {({item, index}) => {                        return (<TouchableOpacity onPress={() => item.screenName}><Surface style={styles.surface}><ImageBackground                            source={item.img}                             style={styles.img}                            blurRadius={0.5}><Icon name="music" color="#fff" size={22}/><Text style={styles.name}>{item.name}</Text></ImageBackground></Surface></TouchableOpacity>                        );                    }}                /></View>

I'm new at React-Native. I'm trying to build an app on mobile. But when I run this code I'm getting this error: React.createElement: type is invalid -- expected a string (for built-in components). My App.js:

import React from 'react';import { StyleSheet, View } from 'react-native';import { Header } from './components/Header';export default function App() {  return (<View style={styles.screen}><Header title="guess a number"/></View>  );}const styles = StyleSheet.create({  screen:{    flex: 1  }});

My Header.js:

import React from 'react';import { View, Text, StyleSheet } from 'react-native';const Header = props => {    return(<View style={styles.header}><Text style={styles.headerTitle}> {props.title}</Text></View>    );};const styles=StyleSheet.create({    header: {        width:'100%',        height:90,        paddingTop: 36,        backgroundColor:'#f7287b',        alignItems: 'center',        justifyContent: 'center'    },    headerTitle: {        color:'black',        fontSize: 18    }});export default Header;

What should i do?

I am new to react-native and payment gateway and creating an android app,I am using "react": "16.9.0","react-native": "0.60.5","react-native-razorpay": "^2.1.30",

also i linked the using react-native link react-native-razorpay

and imported package as

import RazorpayCheckout from 'react-native-razorpay';

and calling gateway as :

    RazorpayCheckout.open(options).then((data) => {       .............        alert(`Success: ${JSON.stringify(data)}`);    }).catch((error) => {        alert(`Error: ${JSON.stringify(error)}`);    });

the code works when i am running the app in debug mode, but when i create apk using bundleRelease and assembleRelease.

apk works fine until i try to make payment.

My conclusion : when apk goes to the RazorpayCheckout.open function call app crashes. I dont know how to debug that and hit a dead end here.

I need to implement an accessibility feature of Voiceover(ios) or talkback(android) in React-native webview for both android and ios.

I am facing two issues:

1: I have div's and paragraphs (p tag) whose content has been read out by device. But I need to add some string as prefix or postfix in those.

Example

code is: <div> Hey Tap me to see magic </div>

Spoken content needed: 1 element of list "Hey Tap me to see magic" click to perform xyz action

.

2: Whenever action happen (i.e. on double tap of element) Device should speak:"Magic has happened"

What I have tried

I have tried using speechSynthesis of HTML% Text to Speech:var msg = new SpeechSynthesisUtterance('Hello World');window.speechSynthesis.speak(msg);

This approach is working for my 2nd issue in ios (iphone X),But No response in android devices

Thanks
