未从ACTION_BATTERY_CHANGED更新BroadcastReceiver

Question

我已经创建了自定义的广播接收器来监听电池的变化(我想监控电池的百分比水平)

然而，我没有得到任何更新。下面是我的设置：

class MyService : IntentService("MyService") {

val receiver: PowerConnectionReceiver = PowerConnectionReceiver()

override fun onHandleIntent(intent: Intent?) {
  Timber.d("Service started now")
}

override fun onCreate() {
 val batteryStatus: Intent? = 
 IntentFilter(Intent.ACTION_BATTERY_CHANGED).let { ifilter ->
  registerReceiver(receiver, ifilter)
 }

}

class PowerConnectionReceiver : BroadcastReceiver() {

override fun onReceive(context: Context, intent: Intent) {
     val status: Int = intent.getIntExtra(BatteryManager.EXTRA_STATUS, -1)
    Timber.d("Battery changed")
    }
  }
}

Answer 1

您将在IntentService运行的<1毫秒内收到更新。只要onHandleIntent()返回，您的IntentService就会关闭。IntentService是为短期的事务性工作而设计的，而不是长期的操作。

切换到常规Service。确保它是前台服务(使用startForeground())，否则它只会在安卓8.0+上运行1分钟。
