WorkManager beginUniqueWork doesn't work as expected

Question

Currently, I\'m using WorkManager 1.0.0-alpha02.

def work_version = \"1.0.0-alpha02\"
implementation \"android.arch.work:work-runtime:$work_version\" // use -ktx         


        

Answer 1

The answer from @ianhanniballake is of course helpful and correct, but I thought I'd point out that (with a fast-evolving API) there is a new enqueueUniqueWork() method so I guess the OP could now use:

workManager.enqueueUniqueWork(
    SyncWorker.TAG,
    ExistingWorkPolicy.REPLACE,
    oneTimeWorkRequest
);

Answer 2

beginUniqueWork() returns a WorkContinuation object. You need to call enqueue on that WorkContinuation to actually enqueue it with WorkManager:

workManager.beginUniqueWork(
    SyncWorker.TAG,
    ExistingWorkPolicy.REPLACE,
    oneTimeWorkRequest
).enqueue();
