问题
startLocalOnlyHotspot 和创建热点的编程方式
我尝试以编程方式创建一个类似于此应用的热点，但问题是热点创建后立即消失。
以下是我正在使用的代码：
private val wifiManager: WifiManager by lazy {
(applicationContext.getSystemService(Context.WIFI_SERVICE) as WifiManager)
}
startLocalOnlyHotspot(object : WifiManager.LocalOnlyHotspotCallback() {
override fun onStarted(reservation: WifiManager.LocalOnlyHotspotReservation) {
super.onStarted(reservation)
}
override fun onStopped() {
super.onStopped()
}
override fun onFailed(reason: Int) {
super.onFailed(reason)
}
}, Handler(Looper.getMainLooper()))
我还尝试过使用前台服务和 WorkManager，但没有成功。当我检查我的 logcat 时，我看到热点被创建，但立即消失，并显示以下错误消息：
系统资源无法调用 close。

I am trying to create a hotspot programmatically similar to this app my problem is hotspot
create and immediately disappear
Here is the code I am using:
private val wifiManager: WifiManager by lazy {
(applicationContext.getSystemService(Context.WIFI_SERVICE) as WifiManager)
}
startLocalOnlyHotspot(object : WifiManager.LocalOnlyHotspotCallback() {
override fun onStarted(reservation: WifiManager.LocalOnlyHotspotReservation) {
super.onStarted(reservation)
}
override fun onStopped() {
super.onStopped()
}
override fun onFailed(reason: Int) {
super.onFailed(reason)
}
}, Handler(Looper.getMainLooper()))
I have also tried this code with foreground service and WorkManager but it did not work. When I check my logcat, I see that the hotspot is created but disappears immediately with the following error message:
> System resource failed to call close.

将reservation对象保留为字段，像这样：
private WifiManager.LocalOnlyHotspotReservation reservation
英文:
keep the reservation object as a field like this :
private WifiManager.LocalOnlyHotspotReservation reservation
