I did something that works but I am still a bit confused.

The manifest in App A, App B and App C, is the same,
as the user doesn't have to nstall App A. But I still want the my
service to be running.

So in all the manifests I did something like

<service android:enabled="true" android:exported="true"
                        android:name=".TestService">
                        <intent-filter>
                                <category 
android:name="android.intent.category.DEFAULT" />
                                <action 
android:name="com.myprivate.action.MARK" />
                        </intent-filter>
</service>

and in all

App A/B/C/D.Activity.onCreate() {
...
Intent intent = new Intent("com.myprivate.action.MARK");
                startService(intent);
...
}

And the outcome that startService doesn't create the service if it is
already exist.
And the "Package Name" of the service is of the FIRST installation.

I don't understand why while there are 2 (or more) identical intent
filters, we don't get an error message
of collision.
In case of Activities we can manually choose which activity will
handle the intent.
