Answer 1

我们无法直接为您提供代码，因为您的知识，我们建议您使用步骤或一些代码快照来指导您。

。实施firebase Job Dispatcher Firebase JobDispatcher
。成功添加库后，会创建一个扩展JobService的服务，如下所示。

import com.firebase.jobdispatcher.JobParameters;
import com.firebase.jobdispatcher.JobService;

public class MyJobService extends JobService {
    @Override
    public boolean onStartJob(JobParameters job) {
        // Do some work here
        //getLatestLocationAndUpdateOnserver()
        //Don't miss to reschedule job
        return false; // Answers the question:z "Is there still work going on?"
    }

    @Override
    public boolean onStopJob(JobParameters job) {
        return false; // Answers the question: "Should this job be retried?"
    }
}

。最后，安排Job-like bellow

private void scheduleJob() {
        FirebaseJobDispatcher dispatcher = new FirebaseJobDispatcher(new GooglePlayDriver(this));
        Bundle myExtrasBundle = new Bundle();
        myExtrasBundle.putString("request_sender", "Data Want to add");
        com.firebase.jobdispatcher.Job myJob = dispatcher.newJobBuilder()
                .setService(MyJobService.class) // the JobService that will be called
                .setTag("my-unique-tag")
                .setTrigger(Trigger.executionWindow(600, 610)) //this will fire after 10minute 
                .setReplaceCurrent(true)// uniquely identifies the job
                .setExtras(myExtrasBundle)
                .build();
        if (dispatcher != null) {
            dispatcher.cancel("my-unique-tag");
        }
        dispatcher.mustSchedule(myJob);
    }
