If you are planning to start a fresh integration, please visit this documentation. This doc is exclusively for the developers who are planning to migrate from the SDK with GCM to the SDK with FCM.

1. Import your GCM project as a Firebase project

Official documentation

2. Add Firebase to your project

Add Firebase to Your App.

3. Add FCM sdk in the app-level build.gradle

dependencies {
  compile "com.google.firebase:firebase-messaging:9.0.0"
}

4. Remove the permissions required by GCM

AndroidManifest.xml - Before

<!-- For GCM notification -->
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />

<!-- Important: Replace 'com.blueshift.sampleapp' with your app's package name -->
<permission
    android:name="com.blueshift.sampleapp.permission.C2D_MESSAGE"
    android:protectionLevel="signature" />

<!-- Important: Replace 'com.blueshift.sampleapp' with your app's package name -->
<uses-permission android:name="com.blueshift.sampleapp.permission.C2D_MESSAGE" />

<!-- For scheduling network operations effectively -->
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

<!-- For analytical purpose (optional) -->
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

AndroidManifest.xml - After

<uses-permission android:name="android.permission.INTERNET" />

<!-- For scheduling network operations effectively -->
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

<!-- For analytical purpose (optional) -->
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

5. Remove the receiver from the app manifest

AndroidManifest.xml - Before

<receiver
    android:name="com.blueshift.gcm.GCMBroadcastReceiver"
    android:permission="com.google.android.c2dm.permission.SEND">
    <intent-filter>
        <action android:name="com.google.android.c2dm.intent.RECEIVE" />
        <action android:name="com.google.android.c2dm.intent.REGISTRATION" />

        <!-- Important: Replace 'com.blueshift.sampleapp' with your app's package name -->
        <category android:name="com.blueshift.sampleapp" />
    </intent-filter>
</receiver>

<service android:name="com.blueshift.gcm.GCMIntentService" />

<!-- Important: Replace 'com.blueshift.sampleapp' with your app's package name -->
<receiver android:name="com.blueshift.rich_push.RichPushBroadcastReceiver">
    <intent-filter>
        <action android:name="com.blueshift.sampleapp.RICH_PUSH_RECEIVED" />

        <category android:name="com.blueshift.sampleapp" />
    </intent-filter>
</receiver>

<meta-data
    android:name="com.blueshift.gcm_sender_id"
    android:value="id:YOUR_GCM_SENDER_ID" />

AndroidManifest.xml - After

<!-- No receiver needed. Yay! -->

6. Deep link receiver

AndroidManifest.xml - Before

<receiver android:name="com.blueshift.rich_push.RichPushActionReceiver">
    <!-- Important: Replace 'com.blueshift.sampleapp' with your app's package name -->
    <intent-filter>
        <action android:name="com.blueshift.sampleapp.ACTION_VIEW" />
        <action android:name="com.blueshift.sampleapp.ACTION_BUY" />
        <action android:name="com.blueshift.sampleapp.ACTION_OPEN_CART" />
        <action android:name="com.blueshift.sampleapp.ACTION_OPEN_OFFER_PAGE" />
        <action android:name="com.blueshift.sampleapp.ACTION_OPEN_APP" />

        <category android:name="com.blueshift.sampleapp" />
    </intent-filter>
</receiver>

AndroidManifest.xml - After

<!-- Important Note: This change is not required if you're using SDK version 2.0.0 and above -->

<receiver android:name="com.blueshift.rich_push.RichPushActionReceiver">
    <!-- Important: Replace 'com.blueshift.sampleapp' with your app's package name -->
    <intent-filter>
        <action android:name="com.blueshift.sampleapp.ACTION_VIEW" />
        <action android:name="com.blueshift.sampleapp.ACTION_BUY" />
        <action android:name="com.blueshift.sampleapp.ACTION_OPEN_CART" />
        <action android:name="com.blueshift.sampleapp.ACTION_OPEN_OFFER_PAGE" />
        <action android:name="com.blueshift.sampleapp.ACTION_OPEN_APP" />

        <category android:name="com.blueshift.sampleapp" />
    </intent-filter>
</receiver>

Register the FCM services for Blueshift SDK

For SDK version v1.1.2.fcm and above, register the following services to do the FCM registration and Message handling by the SDK.

XML

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

<service android:name="com.blueshift.fcm.BlueshiftInstanceIdService">
    <intent-filter>
        <action android:name="com.google.firebase.INSTANCE_ID_EVENT"/>
    </intent-filter>
</service>
