Unable to receive notification when app is closed

[wahyu-handayani]

Hi I am using onesignal_flutter: ^3.4.1 and successfully getting notification when I open my app. But when I close my app from background, I didn't get any notification although the status is delivered from onesignal
Here is android/build.gradle

buildscript {
    ext.kotlin_version = '1.6.10'
    repositories {
        google()
        mavenCentral()
        gradlePluginPortal()
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:7.1.2'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath 'gradle.plugin.com.onesignal:onesignal-gradle-plugin:[0.12.10, 0.99.99]'
    }
}

allprojects {
    repositories {
        google()
        mavenCentral()
        jcenter()
    }
}

rootProject.buildDir = '../build'
subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"
}
subprojects {
    project.evaluationDependsOn(':app')
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

and here is android/app/build.gradle

def localProperties = new Properties()
def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) {
    localPropertiesFile.withReader('UTF-8') { reader ->
        localProperties.load(reader)
    }
}

def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null) {
    throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
}

def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) {
    flutterVersionCode = '1'
}

def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null) {
    flutterVersionName = '1.0'
}

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"
apply plugin: 'com.onesignal.androidsdk.onesignal-gradle-plugin'

buildscript {
    repositories {
        // ...
        maven { url 'https://plugins.gradle.org/m2/' } // Gradle Plugin Portal
    }
    dependencies {
        // ...
        // OneSignal-Gradle-Plugin
        classpath 'gradle.plugin.com.onesignal:onesignal-gradle-plugin:[0.12.10, 0.99.99]'
    }
}


android {
    compileSdkVersion 32
    ndkVersion flutter.ndkVersion

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }

    kotlinOptions {
        jvmTarget = '1.8'
    }

    sourceSets {
        main.java.srcDirs += 'src/main/kotlin'
    }

    defaultConfig {
        // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
        applicationId "com.example.onesignal_notif"
        // You can update the following values to match your application needs.
        // For more information, see: https://docs.flutter.dev/deployment/android#reviewing-the-build-configuration.
        minSdkVersion 21
        targetSdkVersion 31
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
    }

    buildTypes {
        release {
            // TODO: Add your own signing config for the release build.
            // Signing with the debug keys for now, so `flutter run --release` works.
            signingConfig signingConfigs.debug
        }
    }
}

flutter {
    source '../..'
}

dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    implementation 'com.onesignal:OneSignal:[4.0.0, 4.99.99]'
}

is there something that I missed inside build.gradle ? I also open my question on https://stackoverflow.com/questions/73316209/unable-to-receive-notification-from-onesignal-when-app-is-closed-from-background

Hello,

add OneSignal.OSRemoteNotificationReceivedHandler code in Native and also meta tag for it..

Hello,

can you show how to implement this??

[krishnapandya]

add NotificationServiceExtension.kt at native side

          import android.content.Context
          import com.onesignal.OSNotificationReceivedEvent
          import com.onesignal.OneSignal
          import android.app.Notification              
          import android.R
          import androidx.core.app.NotificationCompat              
          
          class NotificationServiceExtension : OneSignal.OSRemoteNotificationReceivedHandler {
              override fun remoteNotificationReceived( context: Context,notificationReceivedEvent: OSNotificationReceivedEvent
              ) {
                  val notification = notificationReceivedEvent.notification
                  val mutableNotification = notification.mutableCopy()
                  notificationReceivedEvent.complete(mutableNotification)
              }
          }

add that in manifest::

  <meta-data
                android:name="com.app.onesignal.NotificationServiceExtension"
                android:value="com.app.view.services.NotificationServiceExtension" />

                android:value="com.app.view.services.NotificationServiceExtension" />

how about for java? Thanks

[rituapplocum]

@krishnapandya Is the above solution working for you?

[tukuttemita]

This is a fatal problem, whether to use this pub or not.

Hello everyone! Apologies that this issue has gone stale.

Based on the original issue description, it sounds as though notifications are not received when the app is in a force-closed state. While undesirable, this is expected behavior on some Android devices. We have some troubleshooting steps to try here.

I'm going to close this issue but please @ mention me if there are still questions or concerns.

Thanks!
