java – Android GCM with product flavors

Posted by: admin May 14, 2020 Leave a comment


I have GCM sample android gradle project. Its worked well, when I add 2 flavors a push notification stopped to work. My compilation manifest (it’s taken from app\build\intermediates\manifests\ex\debug) file is below:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    <uses-permission android:name="com.flavor.app.permission.C2D_MESSAGE" />

        android:protectionLevel="signature" />

            android:permission="com.google.android.c2dm.permission.SEND" >
                <action android:name="com.google.android.c2dm.intent.RECEIVE" />
                <action android:name="com.google.android.c2dm.intent.REGISTRATION" />

                <category android:name="com.flavor.app" />

        <service android:name="com.ex.app.GCMIntentService" />
            class=".AppLocationService" >
                    android:value=".AppLocationService" />

What should I do to fix this problem? Please help.

UPD1. I am using gradle v.0.12+. i think my final manifest file looks good, GCMRegistrar.checkManifest(this); – without errors, but GCMRegistrar.isRegistered(this) always false. =(

UPD2. My first flavor project with original package name (as project in main branch) works well, but second flavor with changed package doesn’t work (registrationId for push is still empty), but in manifest file all permitions are correct.

How to&Answers:

Simpy use the ${applicationId} alias like this

<permission android:name=            "${applicationId}.permission.C2D_MESSAGE"
            android:protectionLevel= "signature" />
<uses-permission android:name=       "${applicationId}.permission.C2D_MESSAGE" />
<uses-permission android:name=       "com.google.android.c2dm.permission.RECEIVE" />

And for the corresponding receiver use this

        android:name = "com.mixpanel.android.mpmetrics.GCMReceiver"
        android:permission = "com.google.android.c2dm.permission.SEND">
            <action android:name = "com.google.android.c2dm.intent.RECEIVE"/>
            <action android:name = "com.google.android.c2dm.intent.REGISTRATION"/>

            <category android:name = "${applicationId}"/>


I found solution in this post GCM not registering when changing package name with Gradle. I just override BroadcastReceiver, if anyone can explain why it helpes please tell me.
