4. WHAT IS JOBSCHEDULER? • API 21 -> JobScheduler class. • can be used to schedule everything that is not time critical for the user
5. COMPARISON • Conditional scheduling • run only when device is on power supply • tasks that require network access or a Wi-Fi connection. • device is idle • start after, deadline, predefined time interval • batch jobs
7. extend the JobService class, implement the onStartJob and onStopJob. return true from on the onStopJob to restart the job. The onStartJob is performed in the main thread, if you start asynchronous processing in this method, return true otherwise false.
9. STEP 1 • register in AndroidManifest.xml • BIND_JOB_SERVICE allows JobScheduler to access our service and only it can do it <service
 android:name=".service.TestJobService"
 android:permission="android.permission.BIND_JOB_SERVICE"
 android:exported="true"/>
