android–JobScheduler不重复工作

概述我正在使用JobScheduler.setPeriodic()来重复我的JobIntentService.它第一次工作但从不重复.在Android7.0上运行ConcurrentCheck.javaintmdelaymilles=30000;JobSchedulerjobScheduler=(JobScheduler)mActivity.getSystemService(JOB_SCHEDULER_SERVICE);Com

我正在使用JobScheduler.setPeriodic()来重复我的JobIntentService.它第一次工作但从不重复.在Android 7.0上运行

ConcurrentCheck.java

int mdelaymilles  = 30000;JobScheduler jobScheduler = (JobScheduler) mActivity.getSystemService(JOB_SCHEDulER_SERVICE);        Componentname componentname = new Componentname(mActivity, ConcurrentCheckService.class);        JobInfo jobInfo = new JobInfo.Builder(JOB_ID, componentname)                .setPeriodic(mdelaymilles)                .setrequiredNetworkType(JobInfo.NETWORK_TYPE_ANY)                .build();        int resultCode = jobScheduler.schedule(jobInfo);        if (resultCode == JobScheduler.RESulT_SUCCESS) {            Log.d(LOG_TAG, "Job scheduled!");            Intent intent = new Intent();            intent.putExtra(LAST_position, lastposition);            JobIntentService.enqueueWork(mActivity, ConcurrentCheckService.class, JOB_ID, intent);        } else {            Log.d(LOG_TAG, "Job not scheduled");        }

解决方法:

可安排工作的最短时间为15分钟.如果设置为小于15分钟的值,则作业将使用15分钟.

请参阅：JobInfo中的MIN_PERIOD_MILLIS.

另外,请在代码中看到此comment：

query the minimum interval allowed for periodic scheduled jobs.
Attempting to declare a smaller period that this when scheduling a job
will result in a job that is still periodic, but will run with this
effective period. A recurring task with your interval will need some
other service, possibly the Alarm Manager will work for you.
