Android: package-related intents not fired

I'm developing a launcher application, I just added a broadcast receiver I will use to update the app list. I initially tried to receive ACTION_PACKAGE_ADDED and ACTION_PACKAGE_REMOVED as they seemed enought for the job, however none where fired so I added all other package-related actions I deemed useful and tried to register for them both in the activity:

val intentFilter = IntentFilter()
        intentFilter.addAction(Intent.ACTION_PACKAGE_ADDED)
        intentFilter.addAction(Intent.ACTION_PACKAGE_REMOVED)
        intentFilter.addAction(Intent.ACTION_PACKAGE_FULLY_REMOVED)
        intentFilter.addAction(Intent.ACTION_PACKAGE_INSTALL)
        intentFilter.addAction(Intent.ACTION_PACKAGE_REPLACED)
        val rec = AppsInstallationsReceiver()
        registerReceiver(rec, intentFilter)

and manifest:

<receiver android:name=".core.installed_apps.AppsInstallationsReceiver">
            <intent-filter>
                <action android:name="android.intent.action.PACKAGE_ADDED" />
                <action android:name="android.intent.action.PACKAGE_REMOVED" />
                <action android:name="android.intent.action.PACKAGE_FULLY_REMOVED" />
                <action android:name="android.intent.action.PACKAGE_INSTALL" />
                <action android:name="android.intent.action.PACKAGE_REPLACED" />
                <data android:scheme="package"/>
            </intent-filter>
        </receiver>

The receiver itself is nothing special:

class AppsInstallationsReceiver : BroadcastReceiver() {

    override fun onReceive(p0: Context?, p1: Intent?) {
        //TODO
    }
}

turns out I only receive PACKAGE_FULLY_REMOVED and only if it's registered in the manifest. Now this is good enought, but I need a way to know when new apps are installed. Since this is a launcher app this feature is critical. Why am I not receiving anything? the activity of course still exists the background since it is used as launcher.
