Robolectric：错误android.content.res.Resources $ NotFoundException

Question

Error on buildActivity() call of Robolectric. It is getting manifest file correctly but getting an error "android.content.res.Resources NotFoundException: String resource ID 0x7f0b2de8".

Setup : Android Studio 2.3.3 on windows and robolectric-compile 'org.robolectric:robolectric:2.4' and gradle plugin, Android plugin 2.3.2 and GradleVersion 4.4

Tried option "android.enableAapt2=false" in gradle.properties file but is of no use.

@RunWith(RobolectricTestRunner.class)
@Config(manifest="src/main/AndroidManifest.xml", emulateSdk = 18)
public class SignalMonitorActivityTest {
    private SignalMonitorActivity objActivity;
    private ActivityController<SignalMonitorActivity> controller;
    @Before
    public void setUp() throws Exception {
         //Robolectric.setupActivity(SignalMonitorActivity.class);    
        controller = Robolectric.buildActivity(SignalMonitorActivity.class).create();
        controller.start();
        controller.visible();
        controller.resume();
    }

Error :

WARNING: no system properties value for ro.build.date.utc DEBUG: Loading resources for com.ABC.android.com_common_Configuration from .\\src\\main\\res...

Try adding the following in build.gradle

android {
  testOptions {
    unitTests {
      includeAndroidResources = true
    }
  }
}

dependencies {
  testImplementation 'org.robolectric:robolectric:2.4'
}

Try adding this in gradle.properties

android.enableUnitTestBinaryResources=true
