JobService不在Android上运行

我尝试在Android上与JobScheduler和JobService合作 我的安装是RPI(Raspberry PI)运行IOT RPI3 1.0.2

这是我的简单代码:

    package com.mystuff.jobservicetest;

    import android.app.Activity;
    import android.app.job.JobInfo;
    import android.app.job.JobParameters;
    import android.app.job.JobScheduler;
    import android.app.job.JobService;
    import android.content.ComponentName;
    import android.content.Context;
    import android.os.Bundle;
    import android.util.Log;


    public class MainActivity extends Activity {

    private static final String TAG = MainActivity.class.getSimpleName();

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        JobScheduler jobScheduler = (JobScheduler) getSystemService(
                Context.JOB_SCHEDULER_SERVICE);
        ComponentName name = new ComponentName(this, JobServiceTest.class);
        JobInfo jobInfo = new JobInfo.Builder(1,name).setPeriodic(1000).build();
        int result = jobScheduler.schedule(jobInfo);
        Log.d(TAG, "result = "+result);
    }

    public class JobServiceTest extends JobService {

        @Override
        public boolean onStartJob(JobParameters jobParameters) {
            Log.d(TAG, "Service job started");
            return false;
        }

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

androidmanifest.xml看起来很简单,如下所示:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.mystuff.jobservicetest">

    <application>
        <uses-library android:name="com.google.android.things" />

        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.IOT_LAUNCHER" />
                <category android:name="android.intent.category.DEFAULT" />
            </intent-filter>
        </activity>
        <service android:name=".MainActivity$JobServiceTest"
            android:permission="android.permission.BIND_JOB_SERVICE"/>
    </application>

</manifest>

logcat的结果是:

w/jobinfo:1的指定间隔为+1毫秒。夹持到+15毫秒 1的规定弯曲度为+1S0ms。夹紧至+5M0S0ms

d/mainActivity:结果=1

我缺少“服务作业已启动”日志。似乎没有人打电话给OnStartJob。

有什么提示吗?

谢谢
