Android WorkManager Check if Work Is in Queue or Running

NOTE:

In this example, I check WorkInfo using unique work name from Android Schedule Daily Repeating/Reminder Alarm at Specific Time With WorkManager example. Since I am using workManager.enqueueUniqueWork(REMINDER_WORK_NAME, ExistingWorkPolicy.REPLACE, workRequest), I can be sure there is only one WorkInfo for this unqiue work name.
I am using kotlinx-coroutines-guava to convert ListenableFuture from WorkManager.getWorkInfosForUniqueWork to kotlin coroutines suspend function.
If you need to continuously listen to WorkInfo changes, you might want to try getWorkInfosForUniqueWorkLiveData.

Code

suspend fun check(workName: String) {    Timber.d("$workName.check")    val workManager = WorkManager.getInstance()    val workInfos = workManager.getWorkInfosForUniqueWork(workName).await()    if (workInfos.size == 1) {        // for (workInfo in workInfos) {        val workInfo = workInfos[0]        Timber.d("workInfo.state=${workInfo.state}, id=${workInfo.id}")        if (workInfo.state == WorkInfo.State.BLOCKED || workInfo.state == WorkInfo.State.ENQUEUED || workInfo.state == WorkInfo.State.RUNNING) {            Timber.d("isAlive")        } else {            Timber.d("isDead")        }    } else {        Timber.d("notFound")    }}

NOTE: What is WorkInfo.State.BLOCKED?

From this source

BLOCKED : This state occurs only if the work is in a chain and is not the next work in the chain.

ENQUEUED : Work enters this state as soon as the work is next in the chain of work and eligible to run. This work may still be waiting on Constraints to be met.

RUNNING : In this state, the work is actively executing. For Workers, this means the doWork() method has been called.

Usage

val WORK_NAME = ...check(WORK_NAME)
