How to get correct jobs count from JobQueue if set same group id

[shinjikao]

I saw JobQueue's countReadyJobs(Constraint constraint) comment mentioned count as 1 since they cannot be run in parallel, but does exist other way to get job count by specific tag if I set same group id? e.g have 50 jobs set "A" group id in queue, and have 30 jobs set "B" group id in queue, How can I get 50 by countReadyJobs() method?

/**
     * Returns the # of jobs that are waiting to be run
     * @return The number of jobs that are waiting in the queue
     */
    int count();

/**
     * counts the # of jobs that can run now. if there are more jobs from the same group,
     * they are count as 1 since they cannot be run in parallel.
     * <p>
     * Exclude groups are guaranteed to be ordered in natural order.
     *
     * @param constraint The constraint to match the jobs
     *
     * @return The number of jobs that are ready to run
     */
    int countReadyJobs(@NonNull Constraint constraint);

My example code snippet

public SyncJob() {
        super(new Params(1).requireNetwork()
                // Make sure that providers can progress in parallel
                .groupBy(createTag())
                .addTags(createTag())
                .setPersistent(persistent)
                // To avoid duplicates
                .singleInstanceBy());
    }
