Android Robolectric和矢量drawables

我在我的应用程序中使用了一些矢量drawables但仅适用于v21及更高版本 – 它们位于资源文件夹drawable-anydpi-v21中,并且还具有其他api级别的回退位图版本(drawable-hdpi.mdpi,…).

当我使用此配置运行robolectric时

@Config(sdk = 16,application = MyApp.class,constants = BuildConfig.class,packagename = "com.company.app")

我使用这些drawables对视图的膨胀产生以下错误

Caused by: android.content.res.resources$NotFoundException: File ./app/build/intermediates/data-binding-layout-out/dev/debug/drawable-anydpi-v21/ic_info_outline_white_24dp.xml from drawable resource ID #0x7f02010e
Caused by: org.xmlpull.v1.XmlPullParserException: XML file ./app/build/intermediates/data-binding-layout-out/dev/debug/drawable-anydpi-v21/ic_info_outline_white_24dp.xml line #-1 (sorry,not yet implemented): invalid drawable tag vector

build.gradle的相关部分是：

android {
      compileSdkVersion 23
      buildToolsVersion "23.0.3"
      defaultConfig {
        applicationId "com.example.app"
        minSdkVersion 16
        targetSdkVersion 23
        versionCode 79
        versionName "0.39"
        // Enabling multidex support.
        multiDexEnabled true
        vectorDrawableS.UseSupportLibrary = true

        testApplicationId "com.example.app.test"
        testinstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
      }
      testOptions {
        unitTests.returnDefaultValues = true
      }
   }
   dependencies {
    compile 'com.android.support:support-vector-drawable:23.4.0'
    TESTCompile "org.robolectric:robolectric:3.1"
    TESTCompile "org.robolectric:shadows-multidex:3.1"
    TESTCompile "org.robolectric:shadows-support-v4:3.1"
   }

所以即使我已经指定了sdk = 16,Robolectric似乎也从drawable-anydpi-v21中获取了drawables.

<ImageView
    android:contentDescription="@String/content_image_description"
    android:src="@drawable/bAnner"
    android:layout_gravity="right"
    android:layout_width="@dimen/bAnner_width"
    android:layout_height="@dimen/bAnner_height"
    />

@Config(constants = BuildConfig.class,sdk = Build.VERSION_CODEs.LOLLIPOP,packagename = "com.package")
