使用Hilt注入CoroutineWorker [英] Injecting CoroutineWorker using Hilt
本文介绍了使用Hilt注入CoroutineWorker的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在尝试使用匕首刀柄注入协程工人，我已经按照文档中的所有说明进行操作
I am trying to inject a coroutine worker using dagger hilt, I 've followed all the instructions in the documentation
https://developer.android.com/training/dependency-injection/hilt-jetpack 旨在供工人"使用不是协程工人"..
https://developer.android.com/training/dependency-injection/hilt-jetpack which was intended for "Worker" not "coroutine Worker"..
但是它给出了一个错误:
but it gives an error :
java.lang.NoSuchMethodError:没有接口方法getBackgroundExecutor()Ljava/util/concurrent/Executor
..在stackoverflow上发布了相同的问题，答案不适合我的情况
..the same question was posted on stackoverflow with an answer that doesn't suit my case
这是代码和错误
如果能提供帮助，我将不胜感激...这是我的代码
I would be grateful if anyone can help...here's my code

推荐答案
我认为这是不正确的导入语句:以下是代码段
I think it's an incorrect import statement: Here are the snippets
请检查您的Hilt模块是否导入错误.
Please check your Hilt Modules for bad imports.
