notice:
- 1.Only supprot API-21.
- 2.should state "android.permission.BIND_JOB_SERVICE" in Manifest.
1.Get JobScheduler SystemService
JobScheduler jobScheduler = (JobScheduler) getSystemService(Context.JOB_SCHEDULER_SERVICE);
2.Set JobInfo builder
JobInfo.Builder builder = new JobInfo.Builder(1,
new ComponentName(getPackageName(), JobSchedulerService.class.getName()));
builder.setPeriodic( 3000 );
3.extends JobService，achieve onStartJob() & onStopJob().
public class JobSchedulerService extends JobService {
@Override
public boolean onStartJob(JobParameters params) {
mJobHanlder.sendMessage(Message.obtain(mJobHanlder, 1, params));
return false;
};
@Override
public boolean onStopJob(JobParameters params) {
mJobHanlder.removeMessages(1);
return false;
}
}
4.Cancel Job
jobScheduler.cancelAll();

permission : ACCESS_NETWORK_STATE & WAKE_LOCK & RECEIVE_BOOT_COMPLETED
service : android:name="com.github.airk.trigger.TriggerLoop"
receiver : com.github.airk.trigger.PersistReceiver
1.Get Trigger Instance
Trigger trigger = Trigger.getInstance(TriggerActivity.this);
2.New A Job
Job job1 = new Job(new Action() {
@Override
protected void act() {
Toast.makeText(TriggerActivity.this, "btJob1", Toast.LENGTH_SHORT).show();
}
}).attachOn(ThreadSpace.BACKGROUND)
.repeat()
.withExtra(new Condition() {
@Override
public String[] getAction() {
return new String[]{CUSTOM_COND1};
}
});
3.Schedule Job
trigger.schedule(job1, job2, job3, persistAfterRebootJob);

1.Get JobScheduler Instance
JobScheduler jobScheduler=JobScheduler.getInstance(LowAPIJobSchedulerMainActivity.this);
2.Set JobInfo Builder
JobInfo job = new JobInfo.Builder(1,
new ComponentName(getPackageName(), LowAPIJobSchedulerService.class.getName()))
.setMinimumLatency(1000)
.setOverrideDeadline(2000)
.setRequiredNetworkType(JobInfo.NETWORK_TYPE_UNMETERED)

public class LowAPIJobSchedulerService extends JobService {
private Handler mJobHanlder = new Handler(new Handler.Callback() {
@Override
public boolean handleMessage(Message msg) {
Toast.makeText(getApplicationContext(), "JobService task running", Toast.LENGTH_SHORT).show();

4.Cancel Job
