doWork

Override this method to do your actual background processing. This method is called on a background thread - you are required to synchronously do your work and return the androidx.work.ListenableWorker.Result from this method. Once you return from this method, the Worker is considered to have finished what its doing and will be destroyed. If you need to do your work asynchronously on a thread of your own choice, see androidx.work.ListenableWorker.

A Worker is given a maximum of ten minutes to finish its execution and return a androidx.work.ListenableWorker.Result. After this time has expired, the Worker will be signalled to stop.
