Adds vmservices to retrieve android applink settings #125998

chunhtai · 2023-05-03T18:16:53Z

fixes #120408

Added two gradle tasks, one for grabing the application id, one for grabbing app link domains.

Added a new vmservices to call these two gradle tasks and return the result.

The expected work flow is that the devtool will first call a vmservices to grab all avaliable build variants. It will then choose one of the build variant and call this new services to get application id and app link domains.

I need this check to avoid crash when running gradle in flutter modules that are use in add to app scenario

I think this is because you are depending on steps that only exist for apps. But I would expect add to app to work and potentially problems with libraries.

Does this need to be cherry picked into either beta or stable?

for add to app, these tasks can only be added in the main android project.

I think in the future I should refactor this out into a separate gradle plugin to support add-to-app, but I would like to make the decision later when we have more concrete design for add-to-app support in deeplink validation tool.

This doesn't need to be cherry pick as there isn't a client using these tasks yet.

Hi, @chunhtai is this still a work in progress? Seems like you have some tests failing

chunhtai · 2023-05-11T22:38:04Z

These tests failures seem to be related to #126557

+            project.tasks.register("print${variant.name.capitalize()}ApplicationId") {


I think according to https://developer.android.com/reference/tools/gradle-api/7.4/com/android/build/api/variant/ApplicationVariant#applicationId() this depends on some task running that will merge the manifests. That means this task depends on another task (possibly as simple as assembleVariant). Given this I think you should add a dependsOn block as defined here. https://docs.gradle.org/current/userguide/tutorial_using_tasks.html#sec:task_dependencies

I think you might actually want variant.outputs.each see example here https://developer.android.com/build/gradle-tips#configure-dynamic-version-codes to print the applicationId.
But I am not sure how task registration interacts differently if you use outputs.

FWIW I am trying to give good guidance here if you explore these things and they dont work you can ignore my comments.

It looks like it is not depending on any task, I ran it after a clean, and it still works. Also the application id is per applicationvariant I think? i didn't see a property on variantoutput for applicationID.
