工作状态观察者始终处于排队状态 [英] workstatus observer always in enqueued state

问题描述

我试图观察我的 workers 但他们总是处于 queued 状态或者有时它是 RUNNING 但从来没有 SUCCEED 或 FAILED.

I am trying to observe my workers but they are always in queued state or sometime it's RUNNING but never SUCCEED or FAILED.

是 workStatus.state 来自 doWork() 的返回还是不同?

is workStatus.state from return in doWork() or it's different?

这是我的工作脚本:

package com.mockie.daikokuten.sync.workers

import androidx.work.Worker


class TestWorker:Worker()
{

override fun doWork():Worker.Result
{
    return Worker.Result.SUCCESS
}

}

这是观察工人的脚本:

 val test = PeriodicWorkRequest.Builder(
            TestWorker::class.java,
            PeriodicWorkRequest.MIN_PERIODIC_INTERVAL_MILLIS,
            TimeUnit.MILLISECONDS)
            .addTag("test_worker")
            .build()

    WorkManager.getInstance()?.enqueueUniquePeriodicWork("test_worker", ExistingPeriodicWorkPolicy.KEEP, test)

    WorkManager.getInstance()!!.getStatusesByTag("test_worker")
            .observe(this, Observer { workStatus ->
                if (workStatus != null)
                {
                    for(ws in workStatus)
                    {
                        Log.d(":dump2 id ", ws.id.toString())
                        Log.d(":dump2 tag", ws.tags.toString())
                        Log.d(":dump2 state", ws.state.toString())
                    }
                }
            })

这是Logcat中的结果:

this is the result in Logcat:

 07-23 17:12:30.901 29740-29740/com.mockie.daikokuten D/:dump2 tag: [test_worker, com.mockie.daikokuten.sync.workers.TestWorker]
 07-23 17:12:30.901 29740-29740/com.mockie.daikokuten D/:dump2 state: ENQUEUED

推荐答案

对于您的定期工作请求，您应该看到

For your periodic work request you should see

ENQUEUED - RUNNING - ENQUEUED

其中后一个 ENQUEUED 是下一个工作请求的状态.

where the latter ENQUEUED is the state of the next work request.

您可能会在 RUNNING 和 ENQUEUED 之间短暂地获得 SUCCEEDED，但我从未见过这种情况.

You might get very briefly a SUCCEEDED between RUNNING and ENQUEUED, but I have never seen that.

您看到的一次性工作请求

For a onetime work request you see

ENQUEUED - RUNNING - SUCCEEDED

或者你在 doWork() 中返回的任何东西.

or whatever you return in doWork().
