Hi there, please help me understand how to configure

processResources

correctly. What I’m trying to do is: I have a file:

src/main/res/xml/file.xml

which has a string like

<external-path name="my_images" path="Android/data/{$appId}/files/Pictures/" />

. Now I’m trying to replace appId token in gradle build script as follows:

tasks {
    withType<ProcessResources> {
        filesMatching("${projectDir}/src/main/res/xml/file.xml") {
            val tokens = mapOf("appId" to "myApplicationId")
            expand(tokens)
        }
        outputs.upToDateWhen { false }
    }
}

But that seems not working. Build finishes without errors, but if I open that xml file after artifact is produced, the template is not fulfilled. I spend on this a almost a day, please help me understand what’s wrong here.

I think the task type ProcessResources is a task that operates on src/*/resources items. but you are trying to process an android resource. can you use

${applicationId}

in any xml res file or does that only work in the manifest?

Thank you @trevjones I don’t know how didn’t i came across this stackoverflow answer, I’ll try this now. It should work. I think I was just stuck on looking into that ProcessResources as a solution. Out of pure curiosity then: about the task configuration I posted in the beginning, if I want to process and expand some other Android specific templates (in

src/res

not in

src/resources

) will this task be useful at all? I can probably use

from

method of this task for this?

that part gets complicated because of the timing of when that android tool chain handles resource processing. It would probably be more appropriate to implement a custom transform. http://google.github.io/android-gradle-dsl/javadoc/current/
