Android Robolectric and vector drawables
I am using some vector drawables in my app but only for v21 and up - they are in the resource folder drawable-anydpi-v21 and also have fallback bitmap versions for the other api levels (drawable-hdpi.mdpi,...).
When I run a robolectric with this config
@Config(sdk = 16, application = MyApp.class, constants = BuildConfig.class, packageName = "com.company.app")
I get the following error on inflate of the views using these drawables
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
the relevant parts of the build.gradle are:
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"
}
So it looks as though even though i have specified sdk=16 Robolectric seems to take the drawables from drawable-anydpi-v21.
Is this a bug is roboelectric? or
Is there a better way to specify what the APK level is? or
Is there a way to let roboelectric read the vector tag? or
Some other way of doing it?
Do you specifically require your tests to target JELLYBEAN ?
Given you do specifically require your tests to target JELLYBEAN , you may want to put your v21+ assets in the res/drawable-v21 folder instead of res/drawable-anydpi-21 .
I too was recently getting the same error with tests after adding an ImageView to a layout that uses a VectorDrawable as its source.
<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"
/>
Using robolectric v3.1, I was able to get my tests to pass again with the following config annotation:
@Config(constants = BuildConfig.class, sdk = Build.VERSION_CODES.LOLLIPOP, packageName = "com.package")
Hope this helps.
You can do one thing. Take the source of RoboElectric and replace all lines
ContextCompat.getDrawable(context, drawableId)
with
AppCompatDrawableManager.get().getDrawable(context, drawableId)
Compile roboelectric and use it. It will allow roboelectric to use vectors.
