Advanced Usage of WorkManager in multi-process apps
In WorkManager 2.5, we made it easier for multi-process apps to reach out to a specific WorkManager instance running in a designated process.
Now, in WorkManager 2.6, we’ve taken it a step further to add support for Workers to run in any process and allow workers to be bound to a particular process. Multi-process support is particularly useful for apps that need to run Workers in multiple processes. Most apps work well in a single process. But those that require more than one process used to have a hard time managing work between processes. Until now!
Starting from WorkManager 2.6, you can bind a worker to a specific process, using RemoteListenableWorker or RemoteCoroutineWorker. For workers implemented in Kotlin, you should use RemoteCoroutineWorker. Otherwise, you should use RemoteListenableWorker. In this article, we’ll demonstrate a Worker implemented in Kotlin, but for a similar Java implementation, check out our sample linked below.
A RemoteCoroutineWorker can be implemented just like CoroutineWorker. But instead of overriding `doWork`, you override `doRemoteWork`, and then bind to a specified process with two extra arguments provided as part of the input data when building the work request: ARGUMENT_CLASS_NAME and ARGUMENT_PACKAGE_NAME:
For each RemoteWorkerService, you’ll also need to add the service definition in the AndroidManifest like so:
To see these new functionalities in action, check out the new WorkManager Multiprocess Sample that utilizes both RemoteCoroutineWorker and RemoteListenableWorker.
You can also see a detailed list of the changes and improvements we’ve made in WorkManager 2.6 in our release notes here.
