WorkManager 重试不工作

Question

我有一个自定义 backoff policy 的 WorkManager。但这不起作用。

我想在 10 秒的最小退避时间后触发重试。
如果 Worker 作业保留在 WorkManager 中，它们会随机执行/在重新启动应用程序后执行（我不知道它们何时被触发，即使规定的默认值为 30 秒）。

查询工人

public void startWorker() {
    Constraints constraints = new Constraints.Builder()
        .setRequiredNetworkType(NetworkType.CONNECTED)
        .build();
         Log.i("WorkManager", "starting workmanager");

        OneTimeWorkRequest work = new OneTimeWorkRequest.Builder(UploadWorker.class)
                .setInitialDelay(5, TimeUnit.SECONDS)
                .setConstraints(constraints)
                .setBackoffCriteria(BackoffPolicy.LINEAR, WorkRequest.MIN_BACKOFF_MILLIS, TimeUnit.MILLISECONDS) // Custom retry not working
            .build();

    WorkManager.getInstance().enqueue(work);
}

工人

public class UploadWorker extends Worker {

    @Override
    public Worker.Result doWork() {

        // Do the work here--in this case, compress the stored images.
        // In this example no parameters are passed; the task is
        // assumed to be "compress the whole library."
        Log.i("WorkManager", "do some stuff " + getId());

        // Indicate success or failure with your return value:
        return Result.RETRY;

        // (Returning RETRY tells WorkManager to try this task again
        // later; FAILURE says not to try again.)
    }
}

我正在使用 work-runtime 的 1.0.0-alpha07 版本。

这是一个错误还是我遗漏了什么？
