Android Bluetooth StartDiscovery() always returns false

落爺英雄遲暮 提交于 2021-02-18 12:16:04
问题 I am trying to discover bluetooth devices nearby, but startDiscovery() always returns false, as if it is not working. Therefore it is not able to find devices. I saw that i have to include Coarse_Location permission apart from Bluetooth and Bluetooth_Admin, but anyway, it doesn´t work. Here is the code I am trying right now, where there are mainly traces to see how it works: public class BluetoothActivity extends AppCompatActivity { RecyclerView recyclerView; ArrayList<BluetoothDevice>

windows2008 r2 不能启用网络发现解决方法

1.出现的问题:   在“网络和共享中心”-“网络发现”不论如何,“启用”网络发现功能,系统都会自动重置为关闭状态。 2.解决方法: 运行中输入 services.msc-->在里边找到下边上个服务,开启 1.Function Discovery Resource Publication 2.SSDP Discovery 3.UPnP Device Host 开启这三个服务后,就可以 启用网络发现 了。 3.发现网络发现功能已经可以启动,但是仍然无法共享文件? 可以尝试检查“本地连接”属性中的“Microsoft网络的文件和打印共享”是否已经安装启用。 来源: https://www.cnblogs.com/weijie0717/p/3804113.html

windows 无法启动网络发现

1.先启动三个服务,按顺序启动(有依存关系),都改为自启动    Function Discovery Resource Publication   SSDP Discovery   UPnP Device Host 2.启动网络发现   控制面板->网络和Internet->网络和共享中心->更改高级共享设置     如果还无法开启,关闭防火墙,查看以下服务是否为自启动: Server; workstation ; computer Browser ; DHCP clicent ; Remote procedure call ; Remote procedure(RPL)lacator ; DNS clicent ; Function Discorvery Resour public ; UPNP device Host ; SSDP discorvery ; TCP/IP NetBzos Helper. 来源: https://www.cnblogs.com/feiquan/p/10533855.html

java代码运行到Service service = new Service();后台运行到这里停止,无报错解决方案

java代码运行到Service service = new Service();后台运行到这里停止,无报错解决方案。 代码片段: LOGGER.debug("enter appInvoke ..."); Service service = new Service(); LOGGER.debug("createCall..."); 日志打印了enter appInvoke ... ,不报错,下面的日志不能打出来,代码不能执行下去了。而且此时此时的控制台并没有输出任何错误,其实是有报错的,如果用try{} catch (Exception e)是不能输出错误的,这个时候注意了,我们把原来的try{} catch (Exception e)替换成try{} catch (Throwable e),为什么呢 Throwable和Exception的区别可以自行百度,我的理解是Throwable是Exception的父类,这个时候控制台就会出现错误信息,一般情况下会出现: java.lang.NoClassDefFoundError: Could not initialize class org.apache.axis.client.AxisClient... 首先需要去检查一下看看有没有少commons-discovery-0.4.jar,如果导入commons-discovery-0

WCF Discovery simply doesn't work

混江龙づ霸主 提交于 2020-01-30 16:54:40
问题 I'm trying to add ad-hoc discovery to a simple WCF service-client setup (currently implemented by self hosting in a console app). Debugging using VS2010 on windows 7, and doing whatever I can find in online tutorial, but still - the discovery client simply finds nothing. Needless to say if I open a client to the correct service endpoint I can access the service from the client. service code: using (var selfHost = new ServiceHost(typeof(Renderer))) { try { selfHost.Open(); ... selfHost.Close()
