使用WorkManager每隔30分钟执行一次任务

这种方式最低适配到SDK=33

/**
 * 监听设备的时间，获取当前是几点钟了。循环获取，每30分钟获取一次时间
 * reMinutes： 重复回调时间（单位：分钟）

class TimeChecker(private val context: Context, private val reMinutes: Long, private val callback: (String) -> Unit) {

    fun start() {
        val workRequest = PeriodicWorkRequestBuilder<TimeWorker>(reMinutes, TimeUnit.MINUTES)
            .build()

        WorkManager.getInstance(context).enqueueUniquePeriodicWork(
            "TimeWorker",

    inner class TimeWorker(appContext: Context, workerParams: WorkerParameters) : Worker(appContext, workerParams) {
        override fun doWork(): Result {
            val currentTime = Calendar.getInstance().time.toString()
            callback(currentTime)
            return Result.success()
        }
    }
}

Kotlin 复制代码

// 使用示例
val timeChecker = TimeChecker(context) { currentTime ->
    println("Current time: $currentTime")
    // 在这里执行你的逻辑
}

timeChecker.start()
