我使用 Android Studio 将我的 android 项目迁移到 AndroidX，但现在当我使用 Robolectric 启动我的单元测试时出现错误：'java.lang.NoClassDefFoundError: Could not initialize class com.google.android.gms.common.GooglePlayServicesUtil' 但是'com.google.android.gms.common.GooglePlayServicesUtil' 存在，我可以在我的文件中使用这个导入。

我尝试 - 将 gradle 升级到最新版本 5.1.1 - 清理、删除缓存、重启 Android Studio - 升级 Robolectric 和地图库

这是我的测试功能：

    @Test
    public void launchGeographicRestrictionEditionActivity() {
        ActivityController<GeographicRestrictionEditionActivity> controller = Robolectric.buildActivity(GeographicRestrictionEditionActivity.class);
        geographicRestrictionEditionActivity = controller.create()
                .start()
                .resume()
                .visible()
                .get();

        GooglePlayServicesUtil.getRemoteContext(null);

        Assert.assertNotNull(geographicRestrictionEditionActivity);
    }

这是我启动测试时的错误：

这是我的项目中导致问题的代码：inflater

    @Override
    public View onCreateView(final LayoutInflater inflater, final ViewGroup container, final Bundle savedInstanceState) {
        mView = inflater.inflate(getMapLayoutResId(), container, false);
.......

我想在没有此错误的情况下启动测试。
