ServiceNotDeclaredException: The BeaconService is

I get the following error when i run a Unit Test in my Android project (I don't get the error while building the app and running it on a device):

The BeaconService is not properly declared in AndroidManifest.xml. If using Eclipse, please verify that your project.properties has manifestmerger.enabled=true org.altbeacon.beacon.BeaconManager$ServiceNotDeclaredException: The BeaconService is not properly declared in AndroidManifest.xml. If using Eclipse, please verify that your project.properties has manifestmerger.enabled=true

Android Studio automatically merges the AndroidManifest.xml from the Android Beacon Library into my own AndroidManifest.xml, which makes it unnecessary to declare the Beacon Services in my AndroidManifest.xml.

This is my current AndroidManifest.xml (located in my /src/main/ folder, I don't have one in my /src/test/ folder):

<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.xxx.xxx">

        </receiver>
    </application>
</manifest>

I already looked in my manifest-merger-release-report.txt inside my build folder (app/build/outputs/apk/manifest-merger-release-report.txt), but couldn't find any problems.

This is the part which contains the Android Beacon Library:

Any idea what could cause this issue?

When using Robolectric tests with the Android Beacon Library, simply add this line to the top of your test:

BeaconManager.setsManifestCheckingDisabled(true);

This will disable the checking for the proper manifest entries when creating an instance of the BeaconManager. This is necessary, because Robolectric does not give you access to a real AndroidManifest when tests are run. I had encountered the same problem myself when building Robolectric tests inside the library itself. You can see an example of this here:
