HOW TO USE

Creating a One-Time Adhoc Job

// To issue an adhoc task that can continue to run in the background 
CrossJobs.Current.RunTask(async () => 
{
    // your code
});

Scheduling a background job

// first define your job
public class YourJob : IJob
{
    public async Task Run(JobInfo jobInfo, CancellationToken cancelToken)
    {
        var loops = jobInfo.GetValue("LoopCount", 25);

        for (var i = 0; i < loops; i++)
        {
            if (cancelToken.IsCancellationRequested)
                break;

            await Task.Delay(1000, cancelToken).ConfigureAwait(false);
        }
    }
}
var job = new JobInfo
{
    Name = "YourJobName",
    Type = typeof(YourJob),

    // these are criteria that must be met in order for your job to run
    BatteryNotLow = this.BatteryNotLow,
    DeviceCharging = this.DeviceCharging
    NetworkType = NetworkType.Any,
    Repeat = true; //defaults to true, set to false to run once OR set it inside a job to cancel further execution
};

// you can pass variables to your job
job.SetValue("LoopCount", 10);


// lastly, schedule it to go - don't worry about scheduling something more than once, we just update if your job name matches an existing one
CrossJobs.Current.Schedule(job);

Cancelling Jobs

// Cancelling A Job
CrossJobs.Current.Cancel("YourJobName");

// Cancelling All Jobs
CrossJobs.Current.CancelAll();

Running Jobs On-Demand

// Run All Jobs On-Demand
var results = await CrossJobs.Current.RunAll();

// Run A Specific Job On-Demand
var result = await CrossJobs.Current.Run("YourJobName");
