I have an app built in react-native in which I have to share these data to LinkedIn

const options = {            title: 'Share via',            message: 'some message',            image:'images need to be shared' //may be multiple images            } 

I tried so many ways but not working. How can I do this?

Getting this crash quite often on firebase crashlytics.

Versions I'm consuming in my project:

"react": "16.8.6",

"react-native": "0.60.5",

"react-native-splash-screen": "3.2.0",

Unable to understand the cause of it. Let me know if anybody can help.

I have implemented an APP that should allow one device one account which I will pass the uniqueId to Web API to be save alongside with user account row in SQL database. This validation happen on Splash and Authentication screen. The flow as below:

Logic Flow:

Device 1:

1. Splash screen: retrieve value from AsyncStorage. If none, proceed to Authentication. If have value, go to #3
2. Fill username and password and click Login.
3. APP will fetch with web API together with userName, encrypted password and uniqueId retrieved from DeviceInfo module.
4. If uniqueId column in SQL is empty, update the column. If have value, compare with uniqueId param. Condition: MATCH-return OK, NOT MATCH-return multiple login alert as exception.
5. Fetch promise resolve OK:- Save encrypted userId and userName into AsyncStorage and go to Dashboard
6. Fetch promise reject:- Show alert and stay at current screen.
7. Notify Web API to clear the uniqueId column and AsyncStorage will clear the token value when user click Logout button

Device 2:

1. Follow directly as Device 1

Situation:

User register 1 device or 1 account. So, if user have 2 device, they have to logout device 1 and login on device 2 to prevent the "Multiple Device Login" alert.

Problem:

As user reported Device 2 are lost or stolen. Our admin system will clear the uniqueId column for reported login information. But the real deal is(for Android, not familiar with ios yet); If user is not logout and press HOME button which fake the report, the APP will rest at task manager and use Device 1 to login. So at the end, 2 device can use 1 account.

Inquiry for the best solutions for the faced PROBLEM:

1. Do I need to pass the uniqueId everytime the APP will fetch from the Web API to be validated when I will enquiry Web API for data?
2. Is it practical to use Headless JS to check with Web API and inform the UI that multiple device alert and automatically logout the current device?
3. Any other better ideas?

Most of tutorial or example show the validation as I doing now, but not found yet for situation on my problem.

Hi my Android expo build is erroring out in Step 5 (Running Gradle). This error is coming when I build using APK.

i have a problem which i trying to solve for about 3 days and i can't find any working solution. The problem is i can't connect my nox player to adb when i trying to connect with localhost and port 62001. Everything i did is:

-nox_adb.exe

nox_adb.exe connect 127.0.0.1:62001 -> unable to connect to 127.0.0.1:62001.

nox_adb.exe connect 127.0.0.1:5037 -> connected to 127.0.0.1:5037 (but when i trying to run react native project with this deviceId, it returns "No Android devices connected")

-adb.exe (from Android SDK)

adb.exe connect 127.0.0.1:62001 -> unable to connect to 127.0.0.1:62001.

adb.exe connect 127.0.0.1:5037 -> failed to connect to 127.0.0.1:5037.

I have installed whole android studio with (i think) needed libraries, Google USB Driver, sdk platforms, etc.Platform: Windows 7 x64Nox: 6.2.0.0

i have read:

• Nox emulator with React Native - cant connect
• Nox App Player not connect with Android Studio - can't connect to ---:62001, react didn't see device when connected

Could someone tell me what I'm doing wrong?

I installed react-native-image-picker according to the documentation.When I am trying to select the image from the phone (after hitting the button), the emulator is giving me this error-null is not an object (evaluating 'ImagePickerManager.showImagePicker')

My React native's version is 0.59.8

and image picker's version is 0.28.0

this the code-

I'm making a react native app and using a native module to get a "string" inside objective-c ios project.

RCT_EXPORT_MODULE();RCT_EXPORT_METHOD(getEmail:(NSString *)email){  RCTLogInfo(@"Getting %@", email);}

I don't know anything about the Objective-C part and I don't know how to store my "email" into something I can use and retrieve inside the AppDelegate.m

Example : [customFieldsDictionary setObject:email forKey:@"EMail"];

If someone can help or guide me through this, it would be awesome !

Thank you

I have been trying to add ReactNative to my existing android application. I followed the instructions from this link. I could add it but the app gets crashed once I open the react native activity. I have started server using

adb reverse tcp:8081 tcp:8081

and started react-native using

react-native start

I get a dialogue that the js files are loading. But finally end up with a crash. Following is the error that is being printed in logcat:

java.lang.UnsatisfiedLinkError: couldn't find DSO to load: libreactnativejni.so    at com.facebook.soloader.SoLoader.loadLibraryBySoName(SoLoader.java:213)    at com.facebook.soloader.SoLoader.loadLibrary(SoLoader.java:178)    at com.facebook.react.bridge.JSCJavaScriptExecutor.<clinit>(JSCJavaScriptExecutor.java:19)    at com.facebook.react.ReactInstanceManager.onJSBundleLoadedFromServer(ReactInstanceManager.java:413)    at com.facebook.react.ReactInstanceManager.createReactContextInBackground(ReactInstanceManager.java:236)

I am completely lost as I am unable to figure out the cause for this issue.

Thanks in advance.

I googled a lot but none of findings is equal to my case:

1. Only 64-bit Android devices affected (tried on several - all the same)
2. Debug build on same devices attached via USB works with no issues
3. Release signed build hangs on every 64-bit device (tried both 64/32 versions)
4. 32-bit and universal signed release works like a charm on 32-bit devices

How it could be possible that SAME CODE works differently in debug and release, why? Different JS Core used?

[UPD]catlog shows problem with pouchdb replication:

I'm using fetch API post call from react native app to chargebee Node tab for creating new customer and getting JSON response error message on android.

The error in image is coming from handle error console.log(error);

Within my expo SDK36 project, I want to display a website in a web view using https://github.com/react-native-community/react-native-webview

This is the expo documentation https://docs.expo.io/versions/latest/sdk/webview/

I did expo install react-native-webview

Basically, my code look like this live demo : https://snack.expo.io/@kopax/sponaneous-waffle

Within the snack, it work on android and ios, but with real redevice, I keep having blank pages.

Any idea how I can solve this and display a website using a webview?

I also tried:

<WebView      style={{        flex: 1,        width: '100%',        height: '100%',        alignSelf: 'stretch',      }}      source={{        uri: 'https://www.lemonde.fr',      }}      startInLoadingState={true}      scalesPageToFit={true}      javaScriptEnabled={true}      domStorageEnabled={true}      {...props}/>

It's always an empty View.

How can I fix it?

I need to integrate Amazon pay with react native app. But I could not find any solution. Is there any way to implement?

For the app that I am currently working on, I am using the following snippets of code to access the device photo gallery to then replace a default image displayed on the screen. I have the default value set to null which should be fine? This works fine on Android however I receive this error on iPhone devices.

Any ideas on how to fix it? (Avatar is what the image is)

state = {user: {  name: "",  email: "",  password: "",  //Fix it!  //Works on Android for some reason? But fix the emulator error  avatar: null},errorMessage: null

};

handlePickAvatar = async () => {UserPermissions.getCameraPermission()let result = await ImagePicker.launchImageLibraryAsync({  mediaTypes: ImagePicker.MediaTypeOptions.Images,  allowsEditing: true,  aspect: [4, 3]})if(!result.cancelled){  this.setState({user: { ...this.state.user, avatar: result.uri} });}

};

<View style={{position: "absolute", top: 45, alignItems: "center", width: "100%"}}><Text style={styles.greeting}>{'Hello!\nSign up to get started.'}</Text><TouchableOpacity style={styles.avatarPlaceholder} onPress={this.handlePickAvatar}><Image source={{uri:this.state.user.avatar}} style={styles.avatar}/><Ionicons         name="ios-add"        size={40}         color="#00d589"        style={{marginTop:6, marginLeft:2}}></Ionicons></TouchableOpacity></View>

I only seem to receive the JSON value of type NSNULL cannot be converted to a valid URL error on the iPhone emulator due to the state that "avatar" is set to null. I followed this Youtube tutorial exactly up to 4:30 https://www.youtube.com/watch?v=UNFDILca9M8

Is there something I am missing? I have all the packages installed and can't see what the issue is.

I am using react-native-maps 0.23.0 version. I am facing image rendering issue in custom callout in android in API level 26 and above. It's working in API 23 but according to google new policy target API level at least 26 to submit apps on play store that's why I can not use API level 23.

Image not showing in callout in android but in iOS is working fine.

Code:
