Pushmanager

Pushmanager is a small wrapper for FCM (Firebase Cloud Messageing) and your app needs just a few methods to interact with it.

Installation

Add google-services as dependency to your project build.gradle

buildscript {
    ...
    dependencies {
        ...
        classpath "com.google.gms:google-services:4.3.5"
        ...
    }
}

and add jitpackto your repositories

allprojects {
    repositories {
        ...
        maven { url "https://jitpack.io" }
    }
    ...
}

Add this dependency to your app build.gradle and apply the plugin at the bottom:

implementation 'com.github.grumpyshoe:android-module-pushmanager:1.3.1'

...
apply plugin: 'com.google.gms.google-services'

Usage

Get instance of PushManager:

val pushmanager: PushManager = PushManagerImpl

Put your google-services.json to the app-root folder.

Create a class extending PushmanagerMessagingService and implement handleNotificationPayload. Here you can decide if a notification should be silent handled or shown to the user according to it's reason.

class MyService : PushmanagerMessagingService() {

    override fun handleNotificationPayload(context:Context, remoteMessageData: RemoteMessageData): NotificationData? {

      Log.d("PushManager", "handlePayload - ${remoteMessageData.title} - ${remoteMessageData.body}" )

      // create pending intent (example)
      val notificationIntent = Intent(context, SomeActivity::class.java)
      notificationIntent.putExtra("info", "Some information for pending intent")
      notificationIntent.flags = Intent.FLAG_ACTIVITY_CLEAR_TOP or Intent.FLAG_ACTIVITY_SINGLE_TOP
      val contentIntent = PendingIntent.getActivity(context, 0, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT)

      // create notification (example)
      return NotificationData(
            context = context,
            title = remoteMessageData.title ?: "Default Title",
            message = remoteMessageData.body ?: "Default Message",
            channelId = "channel_global_notifications",             // needed SDK >= Android O
            autoCancel = true,
            pendingIntent = contentIntent)
    }
}

Add your implementation to you Manifest.xml

<application ... >

       <service
           android:name=".MyService">
           <intent-filter>
               <action android:name="com.google.firebase.MESSAGING_EVENT"/>
           </intent-filter>
       </service>
       ...

</application>

Register to FCM

Call the method register in your onCreate to register to FCM. Notice that register is a coroutine so you have to use something like GlobalScope.launch to run this function.

pushmanager.register(
      context = this,
      onTokenReceived = { token ->
          Log.d("PushManager", "token received: $token")
      },
      onFailure = { exception ->
          Log.d("PushManager", " error during registration: ${exception?.message}")
      })

Unregister from FCM

To unregister from FCM you need to register first. Notice that unregister is a coroutine so you have to use something like GlobalScope.launch to run this function.

pushmanager.unregister(context)

Topics

Subscribe to Topic

To subscribe to a topic just call subscriptToTopic:

pushmanager.subscriptToTopic(
      topic = "wurst",
      onSuccess = {
          Log.d("PushManager", "successfully subscribed")
      },
      onFailure = { exception ->
          Log.d("PushManager", " error while subscribing: ${exception?.message}")
      })

Unsubscribe from Topic

To unsubscribe from a topic call unsubscriptFromTopic:

pushmanager.unsubscriptFromTopic(
      topic = "wurst",
      onSuccess = {
          Log.d("PushManager", "successfully unsubscribed")
      },
      onFailure = { exception ->
          Log.d("PushManager", "error while unsubscribing: ${exception?.message}")
      })
