I have a periodic task that requesting location updates on the background, but I need to restrict this task too work for a long period of time, as it will drain battery, so I need to stop it after a few minutes (3 min). Does Work Manager provide some mechanism to restrict the task's execution time ?
WorkManager doesn't have this functionality.
There's a hard limit of 10 minutes when running a Worker and then the OS is going to stop the worker (this is possible to overcome promoting a Worker to a foreground service as described on the blog: Use WorkManager for immediate background execution).
If you want to implement a timeout of 3 minutes you need to implement it in your worker.
Using Kotlin and CoroutineWorker this can be implemented using withTimeout over the block of code that you want to run with a time limit:
class MyWorker(
appContext: Context,
private val params: WorkerParameters
) : CoroutineWorker(appContext, params) {
override suspend fun doWork(): Result {
return withTimeout(3 * 60 * 1000) {
// Do a long computation
// ...
return@withTimeout Result.success()
}
}
}
