Define a string in gradle and also use a flavor-specific applicationId

Question

I've seen scripts that manipulate the build tasks of gradle and am now wondering if it's possible to set a string outside the `defaultConfig but treat it as default for all flavors.

Basically I've multiple flavors and all of them have a specific ApplicationId. I want to use that id to set a string resource to be used later in my java code.

defaultConfig {
    minSdkVersion 11
    targetSdkVersion 21
    versionCode 1
    versionName "1.0"
}

productFlavors {
    one {
        applicationId "com.my.app.one"
    }
    two {
        applicationId "com.my.app.two"
    }
}

I want to set a string like this:

resValue "string", "authority", applicationId + ".dataprovider"

What I've tried:

• If I put it in the defaultConfig section the applicationId is still null, thus I get a wrong string
• Putting it to each flavor's section works but since I have multiple flavors creates a lot of code repetition

Looking for an alternative.

P.S. I'm using Android Studio 0.8.12.

Well after a lot of searching I've managed to find the answer to this. Perhaps someone will find this useful.

productFlavors.all {
    resValue "string", "authority", applicationId + ".dataprovider"
}

This simple snippet sets a string to all flavors after their invidual variables have been set. It's kind of like a defaultConfig but not quite since it's executed after the flavor blocks.

Extra:

Turns out I can even set the applicationId! My final result so far is:

def final String AUTHORITY = '.dataprovider'

productFlavors.all {
    applicationId "com.my.app." + name
    resValue "string", "authority", applicationId + AUTHORITY
    buildConfigField "String", "AUTHORITY", "\""+applicationId + AUTHORITY+"\""
}

Now I can get each flavor provider's authority through BuildConfig.AUTHORITY and @string/authority, which I use in the manifest and in my class file respectively:

<provider
    android:name="com.my.app.DataProvider"
    android:authorities="@string/authority"
    android:exported="false" />

public class DataProvider extends ContentProvider {
    public static final String PROVIDER = BuildConfig.AUTHORITY;
    public static final Uri SEARCH_URI = Uri.parse("content://" + PROVIDER + "/search");
}
