Java.util.concurrent.RejectedExecutionException 使用 WorkManager 时

Question

我正在使用工作管理器和 kotlin 协程

implementation "androidx.work:work-runtime-ktx:2.0.0"
implementation 'org.jetbrains.kotlinx:kotlinx-coroutines-core:1.1.0'
implementation 'org.jetbrains.kotlinx:kotlinx-coroutines-android:1.1.0'

我的 worker class 扩展 CoroutineWorker

我这样安排

private const val WORK_TAG = "myWork"
  private val constraints = Constraints.Builder().setRequiredNetworkType(NetworkType.CONNECTED).build()

  fun schedule() {
         val work =
            OneTimeWorkRequestBuilder<MyWorker>().setConstraints(constraints).setInitialDelay(6, TimeUnit.HOURS)
                .addTag(WORK_TAG).build()
        WorkManager.getInstance().enqueue(work)
    }

在 Google Play 控制台中，我注意到某些 Android 版本 (https://ibb.co/DzBkpzy)

出现崩溃

在崩溃报告日志中，我没有看到任何代码行。你能帮助我吗。谢谢

Answer 1

ScheduledThreadPoolExecutor@1c2ffc76[Terminated

工作管理器试图在已终止的线程池上安排任务。由于该线程池不受您控制，而且它似乎不是一个常见问题，因此很难为此创建实际的修复程序。

最多你可以尝试将其报告为 androidx 库中的错误，但如果没有更多信息，它可能不可能 'fixed'

Answer 2

这已在较新版本的 WorkManager 中得到修复。您可以使用版本 2.0.1-rc01 或 1.0.1-rc01。

Answer 3

根据官方发布文档，在2.2.0-rc01版本中进行了修复。

Fixed a bug in the AlarmManager implementation that causes the Service to shutdown prematurely and resulting in a RejectedExecutionException in rare cases
