如何在 Android worker 中检测前一个 worker 失败的一系列 Worker
How to detect within an Android worker that within a sequence of Workers a previous worker has failed
我正在调查 Android 名工人。
api "androidx.work:work-runtime:2.6.0-alpha01"
我正在创建独特的工作，需要多个工人依次 运行
Worker_A -> Worker_B -> Worker_C
如果 Worker_A 或 Worker_B returns Result.failure() 有什么方法可以在 Worker_C[=17= 内检测到这一点]
如 WorkManager 中所述 Chaining Work documentation:
Chains of OneTimeWorkRequest execute sequentially as long as their work completes successfully (that is, they return a Result.success()). Work requests may fail or be cancelled while running, which has downstream effects on dependent work requests.
回答你的问题：
In the event either Worker_A or Worker_B returns Result.failure() is there any approach I can take to detect this within Worker_C?
不，Worker_C 无法检测到 Worker_A 或 Worker_B 的故障，因为它根本不会是 运行。
Chaining and Worker statuses 对此进行了详细介绍。
