Vấn đề trong việc quản lí nhiều Jobs với JobScheduler

Các bác cho em hỏi là làm sao đề mình có thề chạy nhiều Job trong JobScheduler. Khi em code ntn thì nó cứ kêu và chạy cả hai cùng một lúc ( theo cái 1 ) @@

Main

ComponentName componentName = new ComponentName(getPackageName(),JobService.class.getName());
final JobScheduler myjobJobScheduler = (JobScheduler) getSystemService(Context.JOB_SCHEDULER_SERVICE);
final JobInfo builder1 = new JobInfo.Builder(1,componentName).setPeriodic(3000).setPersisted(true).build();
final JobInfo builder2 = new JobInfo.Builder(2,componentName).setPeriodic(10000).setPersisted(true).build();

    btstart.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            myjobJobScheduler.schedule(builder1);
            myjobJobScheduler.schedule(builder2);

        }
    });

    btstop.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Log.d("Stop","stop");
            myjobJobScheduler.cancelAll();
        }
    });

Jobservice

public class JobService extends android.app.job.JobService {
@Override
public boolean onStartJob(JobParameters params) {
Log.d(“param jobinfo id”,params.getJobId()+"");
myjopHander.sendMessage(Message.obtain(myjopHander,params.getJobId(),params));
return true;
}

@Override
public boolean onStopJob(JobParameters params) {
    myjopHander.removeMessages(params.getJobId());
    Log.d("Đã dừng","Dừng "+params.getJobId());
    return false;
}

private Handler myjopHander = new Handler(new Handler.Callback() {
    @Override
    public boolean handleMessage(Message msg) {
        Toast.makeText(getApplicationContext(),"Da chay "+((JobParameters)msg.obj).getJobId(),Toast.LENGTH_SHORT).show();
        jobFinished((JobParameters) msg.obj,true);
        Log.d("RUn ","run "+((JobParameters)msg.obj).getJobId() );
        return false;
    }
});

}

Khi em bấm start thì nó chạy cả 2 cái cùng lúc ( mà cái thừ 2 m để sau 10 s lận mà )
