我想在工业中使用android,
我可以使用slickdevlabs.com库连接到Profilic和Ftdi USB转串口芯片,没有任何问题.
应用程序有一个服务,它在启动时启动,连接到USB串口并执行其他操作.
我的问题是主机设备没有与用户进行任何交互,
所以当android问
Allow the app "MyAPP" to access the USB device ?
[checkmark]Use by default for this USB device
Cancel OK

没有人点击确定.
即使我默认检查使用...复选框,如果我重新插入USB,或重新启动主机设备,它会在下次启动时再次询问.
我使用SuperUser模式运行服务和应用程序,但没有区别,它再次询问.
我添加了意图过滤但没有区别,它每次都会问我.
<intent-filter>
<action android:name="android.hardware.usb.action.USB_DEVICE_ATTACHED" />
<action android:name="android.hardware.usb.action.USB_DEVICE_DETACHED" />

任何意见如何绕过或禁用它?
我有root和SU访问权限.
一个非常简单的问题:
为什么我不能_
在WPF内容中看到(下划线)?
例如,内容
<Label Content="test_t" Name="label2" />

显示为"testt"
(下划线未显示).
如何在WPF XAML资源字典中使用制表符和回车符?
这对我不起作用:
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:system="clr-namespace:System;assembly=mscorlib"
>
<system:String x:Key="test_Key">Tab doesnt work\tTest\rTest</system:String>
</ResourceDictionary>

当我通过FindResource("test_key")检索它时,tab和回车字符都被删除.
我实现了ServiceStack Hello World,除了一件重要的事情外,每件事都没问题.它的SOAP11和SOAP12以及WSDL也无法正常工作.当访问URL http:// localhost:8082/SOAP11 / for SOAP11或SOAP12时,它说:
{
"ResponseStatus":{
"ErrorCode":"NotImplementedException",
"Message":"The method or operation is not implemented.",
"StackTrace":" at ServiceStack.WebHost.Endpoints.Support.EndpointHandlerBase.ProcessRequest(IHttpRequest httpReq, IHttpResponse httpRes, String operationName) in C:\\src\\ServiceStack\\src\\ServiceStack\\WebHost.EndPoints\\Support\\EndpointHandlerBase.cs:line 52\n at ServiceStack.WebHost.Endpoints.AppHostHttpListenerBase.ProcessRequest(HttpListenerContext context) in C:\\src\\ServiceStack\\src\\ServiceStack\\WebHost.EndPoints\\AppHostHttpListenerBase.cs:line 57\n at ServiceStack.WebHost.Endpoints.Support.HttpListenerBase.ListenerCallback(IAsyncResult asyncResult) in C:\\src\\ServiceStack\\src\\ServiceStack\\WebHost.EndPoints\\Support\\HttpListenerBase.cs:line 197"

我是通过控制台主机实现的.我的控制台主机类:
public class AppHost
: AppHostHttpListenerBase
{
public AppHost() //Tell ServiceStack the name and where to find your web services
: base("ServiceStack Examples", typeof(InventoryREST.Hello).Assembly) { }
public override void Configure(Funq.Container container)
{
