JobScheduler多次调用onStartJob(),但作业已完成.一切工作正常,如果我安排一个单一的工作,并等到它完成.但是,如果我同时安排两个或多个具有不同ID的作业,则onStartJob()在调用后再次调用jobFinished().

例如,我使用除ID之外的完全相同的参数来安排作业1和作业2,然后顺序为:

1. onStartJob() 对于工作1和工作2
2. 两个作业都完成了,所以jobFinished()它们都被调用了
3. 之后,onStartJob()对于具有相同ID的两个作业再次调用它

我的工作非常基础而且并不复杂.

public class MyJobService extends JobService {

    @Override
    public boolean onStartJob(final JobParameters params) {
        new Thread(new Runnable() {
            @Override
            public void run() {
                try {
                    // do something

                } finally {
                    // do not reschedule
                    jobFinished(params, false);
                }
            }
        }).start();

        // yes, job running in the background
        return true;
    }

    @Override
    public boolean onStopJob(JobParameters params) {
        // mark my background task as stopped

        // …

我正在写一篇关于JobScheduler的教程,我发现了一个奇怪的行为.我要求在1秒内安排3个不同的作业(.setOverrideDeadline(1000)),但它们都被提交并运行了两次......所以这里的代码:

public class MyApplication extends Application {
    private static final int JOB_ID_HanlderThread = 100;
    private static final int JOB_ID_ExecutorService = 200;
    private static final int JOB_ID_AsyncTask = 300;
    JobScheduler mJobScheduler;
    ExecutorService myExecutorServiceForJobs=null;
    private static MyApplication INSTANCE;
    public static MyApplication getInstance(){
        return INSTANCE;
    }


    /**
