Using build types in Gradle to run same app that uses ContentProvider on one device

Question

I have set up Gradle to add package name suffix to my debug app so I could have release version that I\'m using and debug version on one phone. I was referencing this: http:

My solution is to use placeholder replacement in AndroidManifest.xml. It also handles packageNameSuffix attributes so you can have debug and release as well as any other custom builds on the same device.

applicationVariants.all { variant ->
    def flavor = variant.productFlavors.get(0)
    def buildType = variant.buildType
    variant.processManifest.doLast {
        println '################# Adding Package Names to Manifest #######################'
        replaceInManifest(variant,
            'PACKAGE_NAME',
            [flavor.packageName, buildType.packageNameSuffix].findAll().join()) // ignores null
    }
}

def replaceInManifest(variant, fromString, toString) {
    def flavor = variant.productFlavors.get(0)
    def buildtype = variant.buildType
    def manifestFile = "$buildDir/manifests/${flavor.name}/${buildtype.name}/AndroidManifest.xml"
    def updatedContent = new File(manifestFile).getText('UTF-8').replaceAll(fromString, toString)
    new File(manifestFile).write(updatedContent, 'UTF-8')
}

I have it up on a gist too if you want to see if it evolves later.

I found to be a more elegant approach than the multiple resources and XML parsing approaches.
