android - 协程 worker : interrupt doWork() on cancelPendingIntent action

Question

当触发通知的取消操作时，是否可以取消在 doWork() 中完成的工作？

class TestWorker(context: Context, parameters: WorkerParameters) :
    CoroutineWorker(context, parameters) {

    override suspend fun doWork(): Result {

        setForeground(createForegroundInfo())
        doStuff()
        return Result.success()
    }

    private fun doStuff() {
        for (i in 0..10) {
            Log.d(LOG, "Can this be interrupted?")
            Thread.sleep(1000)
        }
    }

    private fun createForegroundInfo(): ForegroundInfo {
        val cancelIntent = WorkManager.getInstance(applicationContext)
            .createCancelPendingIntent(id)

        val notification = NotificationCompat.Builder(applicationContext, CHANNEL_ID)

            ...

            .addAction(android.R.drawable.ic_delete, "cancel", cancelIntent)
            .build()

        createChannelIfNeeded()
        return ForegroundInfo(1, notification)
    }

Thread.sleep(1000) 不可被协程中断。如果您使用delay(1000)，那么它将按照 this blog post 被中断。 .

private suspend fun doStuff() {
    for (i in 0..10) {
        Log.d(LOG, "Can this be interrupted?")
        delay(1000)
    }
}
