Back-off for a fixed period with JobScheduler
What I am trying to achieve is: Three (may increase) JobServices are scheduled. Each job keeps invoking on a difference set of RESTful APIs from a service until it decides to end. The service API has an hourly quota limitation, and will return a certain code when invoked too frequently. The quota is calculated for each application, meaning invocations by all three jobs are counted as a whole. When a job receives the error code indicating the quota is exceeded, it stops running and wait for re-schedule. Since the quota is hourly basis, the job only needs to wait for 60 minutes for the cool-down. To test the back-off strategy, I had an experiment building the job like this: new JobInfo.Builder(JOB_ID, new ComponentName(this, QuickJob.class)) .setOverrideDeadline(ONE_MINUTE) .setMinimumLatency(HALF_MINUTE) .setRequiredNetworkType(JobInfo.NETWORK_TYPE_ANY) .build(); Basicly what the QuickJob does is it logs the timestamp, calls jobFinished(params, true) and waits for Android to reschedule. From the logs I could see that the first time the job stopped for approximately 1 minute, second time 2 minutes, then it's 4 minutes, 8, ..., which fits the description of the BACKOFF_POLICY_LINEAR policy. However, in my case, as described in the beginning, I only need the job to back-off for an hour, not 1, 2, 4, 8 hours. I thought about triggering the jobs at the start of every hour with AlarmManager, but I think it's nice to have the network type settings over the jobs. Another possible solution I thought about is to have the jobs call jobFinished() with needsReschedule being false, but schedule themselves to run again in the next hour. But this just feels hacky and not... right. So what are my choices now?
