Android robolectric tests manifest merge issue (android beacon library)

Question

I have the simple Test Case

@Config(constants = BuildConfig.class)
@RunWith(RobolectricGradleTestRunner.class)
public class BaseTest  {

   @Test
   public void startEverTestSugarAppAsFirst() {
       BeaconManager.setsManifestCheckingDisabled(true);
   }

}

Unfortunately the runner hits manifestmerger issue

java.lang.RuntimeException: 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

I wonder if there is any simple work around. I've been going through android beacon library test folder and

BeaconManager.setsManifestCheckingDisabled(true);

doesn't help

Answer 1

Somehow the BeaconManager is being constructed before the call to BeaconManager.setsManifestCheckingDisabled(true); The trick is to figure out where to put that line so it does get executed first.

Looking at the stack trace, I see that the BeaconManager gets constructed from com.lucyapp.client.Client.onCreate on line 67:

...
org.altbeacon.beacon.BeaconManager.getInstanceForApplication(BeaconManager.java:244) at 
com.lucyapp.client.Client.onCreate(Client.java:67)
...

Knowing that, perhaps you can figure out where you can put the BeaconManager.setsManifestCheckingDisabled(true); line such that it gets called before com.lucyapp.client.Client.onCreate(Client.java:67)
