Need Context in WorkManager

It depends on what kind of Context do you need. According to the documentation of the Worker class, you can simply call getApplicationContext() method directly from the Worker class to get the Context of the entire application, which should be reasonable in this use case.

The documentation of the Worker class does not mention that calling getApplicationContext() should be the preferred way of getting the Context. On the other hand, it does explicitly document that the public constructor of Worker takes a Context as the first parameter.

public Worker (Context context, 
            WorkerParameters workerParams)

So if you need a context in the Worker class, use the one from its construction.
