Android 在定义的时间间隔内安排作业

Question

I'm wondering is there a possibility in some of the scheduling libraries in Android SDK that can achieve this type of behaviour:

• Schedule some work (ex. ping network)
• It is executed every X seconds
• Executions last for Y minutes

There are some stuff like ScheduledThreadPoolExecutor and some custom solutions, but how could I achieve this with officially approved libraries? Thanks.

Answer 1

Work Manager is the finest option for job scheduling.

1. One-time request.

val workManager = WorkManager.getInstance(context)
val oneTimeRequest = OneTimeWorkRequest.Builder(BackupFileUploadWorker::class.java)
                .setConstraints(constraints)
                .build() 
workManager.enqueueUniqueWork(BackupFileUploadWorker::class.java.simpleName, ExistingWorkPolicy.REPLACE, oneTimeRequest)

2. Periodic Request.

var builder : PeriodicWorkRequest.Builder? = null
var periodicWorkRequest : PeriodicWorkRequest? = null

when(backupSettings.backupDuration){
    context.getString(R.string.backup_type_duration_never) -> {
        return
    }
    context.getString(R.string.backup_type_duration_daily) -> {
        builder = PeriodicWorkRequest.Builder(BackupFileUploadWorker::class.java, 1, TimeUnit.DAYS)
    }
    context.getString(R.string.backup_type_duration_weekly) -> {
        builder = PeriodicWorkRequest.Builder(BackupFileUploadWorker::class.java, 7, TimeUnit.DAYS)
    }
    context.getString(R.string.backup_type_duration_monthly) -> {
        builder = PeriodicWorkRequest.Builder(BackupFileUploadWorker::class.java, 30, TimeUnit.DAYS)
    }
}

periodicWorkRequest = builder?.build()
workManager.enqueueUniquePeriodicWork(BackupFileUploadWorker::class.java.simpleName, ExistingPeriodicWorkPolicy.REPLACE, periodicWorkRequest!!)
