JobScheduler.schedule(作业)未启动JobService

我正在使用一个用于JobScheduler 的lib来处理棒棒糖前设备.我正在使用一个棒棒糖设备.问题是mJobScheduler.schedule(作业)应该启动我的工作服务,但它没有启动.此外,当我包含.setPeriodic(2000)方法时,应用程序崩溃了

堆栈跟踪.

我的主要活动

public class MainActivity extends AppCompatActivity {

JobScheduler mJobScheduler;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    mJobScheduler=JobScheduler.getInstance(this);
    constructJob();
}

private void constructJob() {

    JobInfo job = new JobInfo.Builder(0 /*jobid*/, new ComponentName(this,MyService.class))
            .setMinimumLatency(1000)
            .setOverrideDeadline(2000)
            .setRequiredNetworkType(JobInfo.NETWORK_TYPE_UNMETERED)
            .setRequiresCharging(true)
            .setPeriodic(2000)
            .build();



    mJobScheduler.schedule(job);

}
}

MyService类

public class MyService extends JobService {
@Override
public boolean onStartJob(JobParameters params) {
    Toast.makeText(getApplicationContext(),"onStartjob",Toast.LENGTH_SHORT).show();
    Log.i("tag","onstartjob");
    return false;
}

@Override
public boolean onStopJob(JobParameters params) {
    return false;
}
}

我的清单文件

你不能同时使用setPeriodic()和setOverrideDeadline().

因为在定期作业上设置此属性没有意义,所以这样做会在调用build()时抛出IllegalArgumentException.

请参阅:JobInfo.Builder javadoc
