java.lang.NoSuchMethodError：いいえ仮想メソッドgetSystemService

Question

jobserviceを呼び出すjobschedulerを実装しようとしていますが、これは5分ごとに特定のgeoLocationに費やされた時間を取得するトリガです。下のコードはMarshmallow以上で動作していますが、ロリポップ以下ではクラッシュします。 これはロリポップのために働くだろう、このいずれかを試してみてください

>これは私のログエラー - である>

JobScheduler jobScheduler = context.getSystemService(JobScheduler.class); 

エラー - を作るように私のコード - >

ComponentName serviceComponent = new ComponentName(context, SyncDbToServerJobService.class); 
     JobInfo.Builder builder = new JobInfo.Builder(0, serviceComponent); 
     PersistableBundle bundle = new PersistableBundle(); 
     bundle.putString(Constants.ENTERED_TIME, enteredTime); 
     builder.setPeriodic(intervalMillis).setExtras(bundle).setPersisted(true); 
     builder.setRequiredNetworkType(JobInfo.NETWORK_TYPE_UNMETERED); // require unmetered network 
     builder.setRequiresDeviceIdle(true); // device should be idle 
     builder.setRequiresCharging(false); // we don't care if the device is charging or not 
     JobScheduler jobScheduler = context.getSystemService(JobScheduler.class); 
     jobScheduler.schedule(builder.build()); 

これです

ComponentName jobService = new ComponentName(getApplicationContext().getPackageName(), SyncService.class.getName()); JobInfo.Builder builder = new JobInfo.Builder(0, jobService); builder.setPeriodic(10000); builder.setRequiredNetworkType(JobInfo.NETWORK_TYPE_ANY); jobScheduler = (JobScheduler) this.getSystemService(JOB_SCHEDULER_SERVICE); jobScheduler.schedule(builder.build());
