Gradle not fetching metadata correctly from AndroidManifest.xml when using integration testing

Quick summary: I am trying to do integration testing with gradlew connectedAndroidTest on Android Studio 1.2.2, but I am getting the following error:

Position 28:28-65 : No resource found that matches the given name (at 'value' with value '@integer/google_play_services_version').
Position 31:28-51 : No resource found that matches the given name (at 'value' with value '@string/google_maps_key').

      

        
        
        
      

    

Full story: I have two different AndroidManifest.xml, one for release and one for integration testing / testing.

I am running my benchmarks using:

gradlew connectedAndroidTest

      

        
        
        
      

    

This uses AndroidManifest.xml located at ... / src / androidTest / and builds and runs tests on Android. It looks like this:   

<uses-sdk android:targetSdkVersion="22" android:minSdkVersion="15"/>

<uses-feature
    android:glEsVersion="0x00020000"
    android:required="true"/>

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

<application>
    <meta-data
        android:name="com.google.android.gms.version"
        android:value="@integer/google_play_services_version" />
    <meta-data
        android:name="com.google.android.maps.v2.API_KEY"
        android:value="@string/google_maps_key" />

    <uses-library android:name="android.test.runner"/>
</application>

<instrumentation android:name="android.test.InstrumentationTestRunner"
    android:label="Tests for com.company.app"
    android:functionalTest="false"
    android:handleProfiling="false"
    android:targetPackage="com.company.app"/>

</manifest>

      

        
        
        
      

    

When I run the application myself (not the integration testing bit) it works correctly, i.e. it displays google game version and google map key. However, I get the above error when I do integration testing using the above AndroidManifest.xml.

It has something to do with gradle, using the aforementioned AndroidManifest.xml to create another, but it doesn't get the value "@ integer / google_play_services_version", but just uses it as literal.

Any help would be much appreciated. Thanks to
