JobScheduler problems on Android 8

Question

I have my application that uses JobScheduler to check is it alive or not. As far as it must work in cases:

• User removed app from recent apps
• Smartphone was rebooted or battery was exhausted

Anyway application should launch as soon as it is possible.

I used JobScheduler that worked perfect. But since under sdk26 Android doesn't launch my app if it was removed from recents.

What is the solution now? How can I setup JobScheduler to force it to launch my JobService ?

When you schedule your periodic job, use setPersisted(true) . This will keep the job scheduled even after a reboot. Note: Requires the RECEIVE_BOOT_COMPLETED permission. After your app is installed, your user must open it one time before the scheduled job stays persistent across reboots.

JobInfo jobInfo = new JobInfo.Builder(
                        JOB_ID, new ComponentName(context, MyJobService.class))
                        .setPeriodic(30 * 60 * 1000)
                        .setPersisted(true)
                        .setRequiresBatteryNotLow(true)
                        .build();
