Use package name in XML

Question

I'm using Android Studio to build my application. I would like to use gradle buildTypes. I add a suffix to the package name with applicationIdSuffix to modify the package name for a test build type.

buildTypes {       
    debug {
        runProguard false
        proguardFile 'proguard-rules.txt'
        applicationIdSuffix  '.dev'
        versionNameSuffix  '-dev'
    }
}

Is it possible to use this information in a xml file. My plan is to modify the account type:

<account-authenticator xmlns:android="http://schemas.android.com/apk/res/android"
    android:accountType=<<PACKAGE NAME HERE ??>>
    android:icon="@drawable/icon"
    android:label="@string/app_name"/> 

Thanks!

Here's another temporary workaround until the Android Gradle plugin gets support for placeholders in resource files.

You can dynamically create a String resource via Gradle in the defaultConfig and/or buildTypes and/or productFlavors closure:

android {
    defaultConfig {
        applicationId 'com.foo.bar'
        resValue 'string', 'package_name', applicationId
    }
}

You can then reference it in your authenticator.xml file just like you do for the label:

<account-authenticator xmlns:android="http://schemas.android.com/apk/res/android"
    android:accountType="@string/package_name"
    android:icon="@drawable/icon"
    android:label="@string/app_name"/>
