android - 在 ContentProvider 中获取 WorkManager 实例

Question

我想在内容提供者中安排任务:

class LogProvider : ContentProvider() {
    override fun onCreate(): Boolean {
        Log.i("Lagg", "Initializing LogCollection")
        return try {
            context?.let { LogCollectionInitializer().initializeCollector(it) }
            true
        } catch (e: Exception) {
            false
        }
    }
    // ...
}

初始化器安排工作的地方:

WorkManager.getInstance()
                .enqueueUniquePeriodicWork(
                        CleanLogDatabaseTask.DB_CLEANER_TASK_NAME,
                        ExistingPeriodicWorkPolicy.KEEP,
                        PeriodicWorkRequestBuilder<CleanLogDatabaseTask>(DB_CLEANING_INTERVAL, TimeUnit.MILLISECONDS)
                                .setBackoffCriteria(BackoffPolicy.LINEAR, PeriodicWorkRequest.MIN_BACKOFF_MILLIS, TimeUnit.MILLISECONDS)
                                .build()
                )

问题是我得到这个错误:

 java.lang.IllegalStateException: WorkManager is not initialized properly.  The most likely cause is that you disabled WorkManagerInitializer in your manifest but forgot to call WorkManager#initialize in your Application#onCreate or a ContentProvider.

• 不，我没有禁用 WorkManager init。究竟是什么导致了这个问题？

当我从内容提供商访问 workManager 时，我应该采取不同的行动吗？

众所周知，WorkManager 有自己的内容提供程序。因此，如果您覆盖它并将其优先级设置得更高，它将在其他提供程序之前被初始化。所以在这里:

            android:name="androidx.work.impl.WorkManagerInitializer"
            android:authorities="${applicationId}.workmanager-init"
            android:initOrder="11"
            android:enabled="true"
            android:exported="false" /> ```
