使用集成测试时，Gradle无法从AndroidManifest.xml中正确获取元数据

Question

Quick summary: I am trying to do integration testing using gradlew connectedAndroidTest on Android Studio 1.2.2 but I get 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/instrumentation testing.

I execute my instrumentation tests using:

gradlew connectedAndroidTest

This uses AndroidManifest.xml located at .../src/androidTest/ and builds and runs the android tests. 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 app by itself (not the integration testing bit) it works properly, ie it picks up the google play version and the google maps key. However, I get the above error when I do integration testing using the above AndroidManifest.xml.

It has got something to do with gradle using the above given AndroidManifest.xml to generate another one, but in doing so it doesn't pick up the value of "@integer/google_play_services_version" but rather just uses it as a literal.

Any help would be much appreciated. Thanks

EDIT

apply plugin: 'com.android.application'

android {
    compileSdkVersion 22
    buildToolsVersion "22.0.1"

    defaultConfig {
        applicationId "com.minttea.halalit"
        minSdkVersion 15
        targetSdkVersion 22
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    testOptions {
        unitTests.returnDefaultValues = true
    }
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile 'com.android.support:appcompat-v7:22.2.0'
    compile 'com.loopj.android:android-async-http:1.4.6'
    compile 'com.google.android.gms:play-services:6.+'

    testCompile 'org.json:json:20141113'
    androidTestCompile 'junit:junit:4.12'
}

I guess it's because it's trying to find these resources in the test resources. As a quick solution, try creating res folder under androidTest/ and duplicating the requested resources there.
