找不到Robolectric ShadowGeocoder类文件

Question

我想用Robolectric创建一个ShadowGeocoder：

    Field field = FetchAddressIntentService.class.getDeclaredField("geocoder");
    field.setAccessible(true);
    Geocoder geocoderMemberVariable = (Geocoder) field.get(fetchAddressIntentService);
    ShadowGeocoder shadowGeocoder = Shadows.shadowOf(geocoderMemberVariable);
    shadowGeocoder.setSimulatedResponse(ADDRESS, CITY, STATE, ZIP, COUNTRY_CODE);

但是在Shadows.shadowOf我收到错误：

Error:(63, 48) error: cannot access OverlayItem
class file for com.google.android.maps.OverlayItem not found

在我的gradle我正在使用：

testCompile "org.robolectric:robolectric:3.0"
testCompile 'org.robolectric:shadows-maps:3.0'

如何解决这个问题？
