請試試這個：// the service classimport android.app.job.JobParameters;import android.app.job.JobService;import android.util.Log;/** * JobService to be scheduled by the JobScheduler. * start another service */public class mService extends JobService {    private static final String TAG = "SyncService";    @Override    public boolean onStartJob(JobParameters params) {        Log.d("TAG", "onStartJobb");        return true;    }    @Override    public boolean onStopJob(JobParameters params) {        Log.d("TAG", "onStopJob");        return true;    }}// in main activity@RequiresApi(api = Build.VERSION_CODES.N)public void onResume(){    super.onResume();    JobScheduler scheduler = getSystemService(JobScheduler.class);    if(scheduler.getPendingJob(1) == null) {        ComponentName componentName = new ComponentName(this, mService.class);        //JobInfo.Builder builder = new JobInfo.Builder(0, serviceComponent);        JobInfo.Builder info = new JobInfo.Builder(1, componentName)                .setRequiresCharging(false)                .setRequiredNetworkType(JobInfo.NETWORK_TYPE_UNMETERED)                .setPersisted(true)                .setMinimumLatency(1 * 1000)                .setOverrideDeadline(3 * 1000)                //.setPeriodic(60 * 60 * 1000)                //.build()                ;        int resultCode = scheduler.schedule(info.build());        if (resultCode == JobScheduler.RESULT_SUCCESS) {            Log.d("TAG", "Service is not running, Job " + String.valueOf(1) + " Scheduled.");        } else {            Log.d("TAG", "Service is not running, However job scheduling failed.");        }    } else{        Log.d("TAG", "Service is already scheduled.");    }}請注意，這里是Periodic min interval的限制，不幸的是15分鐘，當我們把它設置得更小，SDK將其更改為15分鐘，并將flex interval設置為5分鐘，最終我們得到服務啟動從作業的調度時間開始大約 7-8 分鐘后。這就對了 ）。這對我有用，
