android - BOOT COMPLETE BroadcastReceiver 自动注册

Question

当用户希望服务在启动时启动时，我正在尝试启动我的服务。所以我在我的设置片段上有一个复选框首选项来控制它。检查框并用户启动服务后，StartOnBootBroadcast将注册广播电台，并在启动完成后开始使用服务。默认情况下，除非用户需要，否则不会注册 BroadcastReceiver。但问题是如果我安装应用程序并重新启动设备，广播接收器会启动服务（但我从未注册过）。我已经用调试器检查了条件，并且启动接收器的条件从未满足。

广播接收器：

class StartOnBootBroadcast : BroadcastReceiver() {

    companion object {
        private var instance: StartOnBootBroadcast? = null
        fun getinstance(): StartOnBootBroadcast {
            if (instance == null) {
                instance = StartOnBootBroadcast()
            }
            return instance as StartOnBootBroadcast
        }
    }

    override fun onReceive(context: Context?, intent: Intent?) {

        Log.d("BOOTCAST", "onReceive: FIRED")
        
        val serviceIntent = Intent(context, MyService::class.java)

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            context!!.startForegroundService(serviceIntent)
        } else {
            context!!.startService(serviceIntent)
        }
    }
}

注册/注销 BroadcastReciever 的方法：

prefViewmodel.getBootStatus.observe(viewLifecycleOwner, Observer { value ->
    onBoot = value
        if (Utilities.getInstance(mContext).isMyServiceRunning(ChargeLoggerService::class.java)){
            startOnBoot(onBoot)
        }
})
