This is what I used
There's this video by Joannes Mike on YouTube I followed on how to remove header and footer in Flutter WebView but it seems flutter had upgraded her library and this functions don't work anymore.
Been at this for days and it seems no recent info is available.
Heres my code
import 'package:sportybet_betting_tips/main.dart';
import 'package:webview_flutter/webview_flutter.dart';
class sportybet_tips extends StatefulWidget {
const sportybet_tips({super.key});
#override
State<sportybet_tips> createState() => _sportybet_tipsState();
}
class _sportybet_tipsState extends State<sportybet_tips>
{
late final WebViewController controller;
#override
void initState(){
super.initState();
controller = WebViewController()
..loadRequest(Uri.parse('https://accessbettingtips.com/sportybet/'),);
// controller.addJavaScriptChannel(
// "document.getElementsByTagName('header')[0].style.display='none'", onMessageReceived: (JavaScriptMessage ) { });
// controller.loadRequest(Uri.parse('http://accessbettingtips.com'),);
}
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: const Text('Sportybet Betting Tips'),
),
body: WebViewWidget(controller: controller),
// controller.evaluateJavascript(
// "document.getElementsByTagName('header')[0].style.display='none'");
// controller.loadRequest(Uri.parse('http://accessbettingtips.com'),);
);
}
// webview_flutter({required JavaScriptMode JavaScriptMode, required String initialUrl}) {}
}
in your onPageFinished method write like that :
onPageFinished: (url) async {
controller.runJavascript("document.getElementsByTagName('header')[0].style.display='none'");
},

I'm using spring boot in my backend and vuejs in my front-end . I've defined everything in the guide yet I still don't get my project to work.
FrontEnd
connectToWS() {
this.socket = new Sock("http://localhost:8754/stomp-endpoint");
this.stompClient = Stomp.over(this.socket);
this.stompClient.connect(
{},
frame => {
this.connected = true;
console.log(frame);
this.stompClient.subscribe("/topic/greetings", tick => {
console.log(tick);
this.received_messages.push(JSON.parse(tick.body).content);
});
},
error => {
console.log(error);
this.connected = false;
}
);
},
Backend
WebSocketConfiguration Class :
#Configuration
#EnableWebSocketMessageBroker
public class WebsocketConfiguration implements
WebSocketMessageBrokerConfigurer
{
#Override
public void registerStompEndpoints(StompEndpointRegistry registry)
{
// with sockjs
registry.addEndpoint("/stomp-endpoint")
.setAllowedOrigins("http://localhost:8081")
.withSockJS();
}
#Override
public void configureMessageBroker(MessageBrokerRegistry config) {
config.setApplicationDestinationPrefixes("/app")
.enableSimpleBroker("/topic");
}
}
WebSecurityConfigClass :
#Override
protected void configure(HttpSecurity http) throws Exception {
http.cors().and().csrf().disable()
.exceptionHandling().authenticationEntryPoint(unauthorizedHandler).and()
.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS).and()
.authorizeRequests()
.antMatchers("/api/v*/registration/**").permitAll()
.antMatchers("/topic**").permitAll()
.antMatchers("/stomp-endpoint").permitAll()
UPDATE :
The error is actually coming out from the browser . It actually changes the route of the api because it has sockjs integrated into it. I couldn't figure out why the API always gets a /info?t=RandomNumber after it. I need the route to remain the same as I typed it in the front-end.
How can I stop the browser from updating my path. Thanks for helping !
I want to render a YooKassa widget in flutter app, so I've written this code to implement it
https://yookassa.ru/checkout-widget/v1/checkout-widget.js
#JS()
library checkout-widget.js;
import 'package:js/js.dart';
#JS('YooMoneyCheckoutWidget')
class YooMoneyCheckoutWidget {
external YooMoneyCheckoutWidget(YooMoneyCheckoutWidgetParams params);
external render(String viewID);
}
#JS()
#anonymous
class YooMoneyCheckoutWidgetParams {
external factory YooMoneyCheckoutWidgetParams({
String confirmation_token,
String return_url,
Map<String, dynamic> customization,
Function error_callback
});
}
class YooKassa {
YooMoneyCheckoutWidget _checkoutWidget;
YooKassa({String confirmation_token,String return_url}):_checkoutWidget = YooMoneyCheckoutWidget(YooMoneyCheckoutWidgetParams(confirmation_token: confirmation_token, return_url: return_url, customization: {'colors': {'controlPrimary':'#00BF96'}},error_callback: null));
void render(String viewID) => _checkoutWidget.render(viewID);
}
then trying to call the constructor for a JS code
final widget = YooKassa(confirmation_token: 'ct-2834a83d-000f-5000-9000-1316627a4610',return_url: 'https://app.moneyhat.ru/');
and then render it in DivElement in a HTMLElement
final wrapper = html.DivElement()
..style.width = '100%'
..style.height = '100%'
..id = 'pay-form';
ui.platformViewRegistry.registerViewFactory(
viewID,
(int viewId) => wrapper,
);
widget.render('pay-form');
return Scaffold(
body: SizedBox(
height: 500,
child: HtmlElementView(
viewType: viewID,
),
));
}
What's wrong here? Flutter raises an error - YooMoneyCheckoutWidget is not a constuctor
This is my very first post here, so please don't blame me if I'm not as complete and clear as I have to be.
The issue
I am new to React native and I recently began to develop a react native app which could read my incoming SMS's aloud. I already achieved to retrieve the incoming messages and to read them aloud... But only if the app is the foreground.
So, could you please advise me some libraries or tutorials on the subject ?
I'm working on a Nokia 5 with Android 9.
I currently use the following libraries :
React-native-android-sms-listener to retrieve the incoming messages.
React-native-tts to read the content aloud.
What I already tried
I'm searching the Internet for more than a week now (includig Stack Overflow and this example question) and I can't find what I'm looking for. I already tried React-native-background-timer and React-native-background-job. But I couldn't never get a background timer working and React-native-background-job allows tasks to be executed every 15 minutes only (due to the Android limitations).
So I read many articles like this one explaining how to use Headless JS and other libraries until I found this codeburst tutorial today, explaining how to develop a background service to record audio calls. I tried to adapt it, but the background service never starts.
My code
I must tell you that I don't have any knowledge in Java, so the native code below may contain mistakes, even if it is based on tutorials and the React native documentation.
Currently, when the app is launched, the service IncomingSMSService is called. This service, developed following the Codeburst tutorial referenced above, relies on Headless JS and a JS function that listen to the incoming messages and then read them aloud thanks to React-native-tts.
Here is these two files :
IncomingSMSService.java
package com.ava.service;
import android.content.Intent;
import android.os.Bundle;
import com.facebook.react.HeadlessJsTaskService;
import com.facebook.react.bridge.Arguments;
import com.facebook.react.jstasks.HeadlessJsTaskConfig;
public class IncomingSMSService extends HeadlessJsTaskService {
#Override
protected HeadlessJsTaskConfig getTaskConfig(Intent intent) {
Bundle extras = intent.getExtras();
if (extras != null) {
return new HeadlessJsTaskConfig(
"HandleIncomingSMS",
Arguments.fromBundle(extras),
5000,
true
);
}
return null;
}
}
HandleIncomingSMS.js
import { AppRegistry } from 'react-native';
import SmsListener from 'react-native-android-sms-listener';
import Tts from 'react-native-tts';
const HandleIncomingSMS = async (taskData) => {
SmsListener.addListener(message => {
Tts.getInitStatus().then(() => {
Tts.speak(`New message from number ${message.originatingAddress} : ${message.body}`);
});
});
}
AppRegistry.registerHeadlessTask('HandleIncomingSMS', () => HandleIncomingSMS));
These pieces of code are called in a BroadcastReceiver here (IncomingSMSReceiver.java) :
package com.ava.receiver;
import android.app.ActivityManager;
import android.app.ActivityManager.RunningAppProcessInfo;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import com.ava.service.IncomingSMSService;
import com.facebook.react.HeadlessJsTaskService;
import java.util.List;
public final class IncomingSMSReceiver extends BroadcastReceiver {
#Override
public final void onReceive(Context context, Intent intent) {
if (!isAppOnForeground((context))) {
Intent service = new Intent(context, IncomingSMSService.class);
context.startService(service);
HeadlessJsTaskService.acquireWakeLockNow(context);
}
}
private boolean isAppOnForeground(Context context) {
ActivityManager activityManager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
List<ActivityManager.RunningAppProcessInfo> appProcesses =
activityManager.getRunningAppProcesses();
if (appProcesses == null) {
return false;
}
final String packageName = context.getPackageName();
for (ActivityManager.RunningAppProcessInfo appProcess : appProcesses) {
if (appProcess.importance ==
ActivityManager.RunningAppProcessInfo.IMPORTANCE_FOREGROUND &&
appProcess.processName.equals(packageName)) {
return true;
}
}
return false;
}
}
I also requested the good permissions in my AndroidManifest file, and I registered the service like so :
<service
android:name="com.ava.service.IncomingSMSService"
android:enabled="true"
android:label="IncomingSMSService"
/>
<receiver android:name="com.ava.receiver.IncomingSMSReceiver">
<intent-filter android:priority="0">
<action android:name="android.provider.Telephony.SMS_RECEIVED"/>
</intent-filter>
</receiver>
What am I doing wrong ? I don't even see service in the Running services tab of the Android Developer options... Any ideas ?
Thanks in advance for your help.
UPDATE (01/06/2019)
After reading or watching several tutorials like this one or this video, I managed to get my app working in the foreground. It now displays a persistent notification.
BUT, I don't know how I can "link" my service and my Broadcsat Receiver to this notification (for now, the service is called only if the app is in foreground).
Here is my updated code :
// IncomingSMSService
package com.ava.service;
import android.graphics.Color;
import android.app.Notification;
import android.app.PendingIntent;
import android.app.Service;
import android.content.Context;
import android.content.ContextWrapper;
import android.app.Notification;
import android.app.NotificationChannel;
import android.app.NotificationManager;
import android.content.Intent;
import android.os.Handler;
import android.os.IBinder;
import android.support.v4.app.NotificationCompat;
import com.facebook.react.HeadlessJsTaskService;
import com.ava.MainActivity;
import com.ava.R;
public class IncomingSMSService extends Service {
private NotificationManager notifManager;
private String CHANNEL_ID = "47";
private int SERVICE_NOTIFICATION_ID = 47;
private Handler handler = new Handler();
private Runnable runnableCode = new Runnable() {
#Override
public void run() {
Context context = getApplicationContext();
Intent myIntent = new Intent(context, IncomingSMSEventService.class);
context.startService(myIntent);
HeadlessJsTaskService.acquireWakeLockNow(context);
handler.postDelayed(this, 2000);
}
};
#Override
public IBinder onBind(Intent intent) {
return null;
}
#Override
public void onCreate() {
super.onCreate();
createNotificationChannel();
}
#Override
public void onDestroy() {
super.onDestroy();
}
public void createNotificationChannel() {
NotificationChannel notificationChannel = new NotificationChannel(CHANNEL_ID, "General", notifManager.IMPORTANCE_HIGH);
notificationChannel.enableLights(true);
notificationChannel.setLightColor(Color.RED);
notificationChannel.setShowBadge(true);
notificationChannel.setLockscreenVisibility(Notification.VISIBILITY_PUBLIC);
getManager().createNotificationChannel(notificationChannel);
}
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
this.handler.post(this.runnableCode);
Intent notificationIntent = new Intent(this, MainActivity.class);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);
Notification notification = new NotificationCompat.Builder(this, CHANNEL_ID)
.setContentTitle("Ava")
.setContentText("Listening for new messages...")
.setSmallIcon(R.mipmap.ic_launcher_round)
.setContentIntent(contentIntent)
.setOngoing(true)
.build();
startForeground(SERVICE_NOTIFICATION_ID, notification);
return START_NOT_STICKY;
}
private NotificationManager getManager() {
if (notifManager == null) {
notifManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
}
return notifManager;
}
}
My headlessJS task :
// HandleIncomingSMS.js
import SmsListener from 'react-native-android-sms-listener';
import Tts from 'react-native-tts';
import Contacts from 'react-native-contacts';
import { text } from 'react-native-communications';
module.exports = async () => {
// To lower other applications' sounds
Tts.setDucking(true);
// Prevent the TTS engine from repeating messages multiple times
Tts.addEventListener('tts-finish', (event) => Tts.stop());
SmsListener.addListener(message => {
Contacts.getAll((err, contacts) => {
if (err) throw err;
const contactsLoop = () => {
contacts.forEach((contact, index, contacts) => {
// Search only for mobile numbers
if (contact.phoneNumbers[0].label === 'mobile') {
// Format the contact number to be compared with the message.oritignatingAddress variable
let contactNumber = contact.phoneNumbers[0].number.replace(/^00/, '+');
contactNumber = contactNumber.replace(/[\s-]/g, '');
// Phone numbers comparison
if (contactNumber === message.originatingAddress) {
if (contact.familyName !== null) {
Tts.speak(`Nouveau message de ${contact.givenName} ${contact.familyName} : ${message.body}`);
} else {
// If the contact doesn't have a known family name, just say his first name
Tts.speak(`Nouveau message de ${contact.givenName} : ${message.body}`);
}
} else if (contactNumber !== message.originatingAddress && index === contacts.length) {
// If the number isn't recognized and if the contacts have been all checked, just say the phone number
Tts.speak(`Nouveau message du numéro ${message.originatingAddress} : ${message.body}`);
}
}
});
}
contactsLoop();
// Redirect to the SMS app
text(message.originatingAddress, message = false);
});
});
}
I also added the good permissions in my AndroidManifest.xml file like the following :
...
<uses-permission android:name="android.permission.FOREGROUND_SERVICE"/>
<uses-permission android:name="android.permission.WAKE_LOCK"/>
...
I made some progress but I am still stuck, so if you have any idea, please share them ! Thank you !
I wrote a simple cordova plugin which displays an alert.
JS file: alert.js
module.exports = {
alert: function(title, message, buttonLabel, successCallback) {
cordova.exec(successCallback,
null, // No failure callback
"Alert",
"alert",
[title, message, buttonLabel]);
}
};
Java File: Alert.java
package com.acme.plugin.alert;
import android.app.AlertDialog;
import android.app.AlertDialog.Builder;
import android.content.DialogInterface;
import org.apache.cordova.CallbackContext;
import org.apache.cordova.CordovaInterface;
import org.apache.cordova.CordovaPlugin;
import org.apache.cordova.CordovaWebView;
import org.apache.cordova.PluginResult;
import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;
public class Alert extends CordovaPlugin {
protected void pluginInitialize() {
}
public boolean execute(String action, JSONArray args, CallbackContext callbackContext)
throws JSONException {
if (action.equals("alert")) {
alert(args.getString(0), args.getString(1), args.getString(2), callbackContext);
return true;
}
return false;
}
private synchronized void alert(final String title,
final String message,
final String buttonLabel,
final CallbackContext callbackContext) {
new AlertDialog.Builder(cordova.getActivity())
.setTitle(title)
.setMessage(message)
.setCancelable(false)
.setNeutralButton(buttonLabel, new AlertDialog.OnClickListener() {
public void onClick(DialogInterface dialogInterface, int which) {
dialogInterface.dismiss();
callbackContext.sendPluginResult(new PluginResult(PluginResult.Status.OK, 0));
}
})
.create()
.show();
}
}
How do I call the alert function of alert.js from another js? And what parameter should i pass to map to successCallback??
according to cordova git for creating plugin see github page you can do it like this
Add the following code to wherever you need to call the plugin functionality:
cordova.plugins.<PluginName>.<method>();
where <PluginName> is your plugin name and <method> is your method.
I'm trying to run a background service in Android using HeadlessJS API from react native. I've used the official docs to do it:
MainTask file:
package com.test.test;
import android.content.Intent;
import android.os.Bundle;
import android.support.annotation.Nullable;
import android.widget.Toast;
import com.facebook.react.HeadlessJsTaskService;
import com.facebook.react.bridge.Arguments;
import com.facebook.react.jstasks.HeadlessJsTaskConfig;
public class MyTaskService extends HeadlessJsTaskService {
#Override
protected #Nullable HeadlessJsTaskConfig getTaskConfig(Intent intent) {
Bundle extras = intent.getExtras();
if (extras != null) {
return new HeadlessJsTaskConfig(
"SomeTaskName",
Arguments.fromBundle(extras),
5000);
}
return null;
}
}
I've also registered the task like this:
AppRegistry.registerHeadlessTask('SomeTaskName', () => 'SomeTaskName')
and SomeTaskName is a function that looks like this:
export async function SomeTaskName (taskData) {
alert('Esto es una tarea en background')
}
The way that I'm using to trigger this background task is using the startService method:
startService(new Intent(this, MyTaskService.class));
I tried startService in different parts of the android code but I can't see any alert or warning logs.
I'm trying to figure this out too. Here's what I've found so far.
If you don't put "extras" into to the Intent you pass to start the service then getTaskConfig() returns null.
protected #Nullable HeadlessJsTaskConfig getTaskConfig(Intent intent) {
Bundle extras = intent.getExtras();
if (extras != null) {
return new HeadlessJsTaskConfig(
"SomeTaskName",
Arguments.fromBundle(extras),
5000);
}
return null;
}
Either remove the check for extras != null, or add something like this before you call startService:
Intent myIntent = new Intent(this, MyTaskService.class);
myIntent.putExtras("isReady",true);
startService(myIntent);
Also, make sure you add the service to the manifest.
<application>
....
<service android:name=".MyTaskService" android:enabled="true" android:label="MyTaskService" />
</application>
You could change your getTaskConfig method to support an intent that has no extras:
#Override
protected #Nullable HeadlessJsTaskConfig getTaskConfig(Intent intent) {
Bundle extras = intent.getExtras();
WritableMap data = extras != null ? Arguments.fromBundle(extras) : null;
return new HeadlessJsTaskConfig(
"SomeTaskName",
data,
5000);
}
Your Application class needs to implement ReactApplication and return an initialized ReactNativeHost, eg:
private final ReactNativeHost reactNativeHost = new ReactNativeHost(this) {
#Override
public boolean getUseDeveloperSupport() {
return BuildConfig.DEBUG;
}
#Override
protected List<ReactPackage> getPackages() {
return Arrays.<ReactPackage>asList(
new MainReactPackage()
);
}
};
#Override
public ReactNativeHost getReactNativeHost() {
return reactNativeHost;
}
You also have to add the service to your manifest, as A. Rob mentioned.
Edit
Instead of implementing ReactApplication (see above) it seems like you could also override protected ReactNativeHost getReactNativeHost() within the HeadlessJsTaskService.
