显示简单的HTML在本机黑莓应用 [英] Display simple HTML in a native BlackBerry application
问题描述
我希望能在我的家乡黑莓手机的应用程序，以显示HTML的一些简单的块，而不是从URL返回。这类似于现有的问题＃1（例如这里和<一个href=\"http://stackoverflow.com/questions/1339384/displaying-html-content-in-a-field-in-blackberry\">here),但我需要帮忙的实际样品黑莓code运行（或者有人告诉我这是为什么注定不行！）。
I want to be able to display some simple chunks of HTML in my native BlackBerry app, NOT returned from a URL. This is similar to existing Stackoverflow questions (e.g. here and here), but I need help getting the actual BlackBerry sample code to run (or perhaps somebody to tell me why this is doomed to not work!).
黑莓网站提供了一些样品'浏览器'code基于可用不同的API版本：结果
<一href=\"http://docs.blackberry.com/en/developers/deliverables/11935/Display%5Fcontent%5Fin%5FBB%5FBrowser%5Ffield%5F565587%5F11.jsp\"相对=nofollow> V4.5 API样本结果
<一href=\"http://docs.blackberry.com/en/developers/deliverables/11935/Display%5FHTML%5Fin%5Fa%5Fbrowser%5Ffield%5F825639%5F11.jsp\"相对=nofollow> V5.0 API样本
The BlackBerry website has some sample 'browser' code based on different API versions available:
V4.5 API sample
V5.0 API sample
我发现样品code附带的组件包（更多信息<一个href=\"http://stackoverflow.com/questions/919126/blackberry-audio-recording-sample-$c$c/1877685#1877685\">here),并试图让V4.5样本code的工作。我希望这将是一个有用的起点......
I've found the sample code that ships with the Component Packs (more info here), and tried to get the V4.5 sample code to work. I was hoping this would be a useful starting point...
我设法BrowserFieldDemo在Eclipse编译并在模拟器中运行（我需要注释掉整个BrowserContentManagerDemo.java否则该类将改为运行）。
I've managed to get BrowserFieldDemo to compile in Eclipse and run in the Simulator (I needed to comment out the whole of BrowserContentManagerDemo.java otherwise that class would run instead).
不幸的是，我只是得到了模拟器白屏。当我在日志中添加和使用调试器，这一切似乎出问题的getBrowserContent（）线在这里：
Unfortunately, I just get a white screen in the Simulator. When I add in logging and use the debugger, it all seems to go wrong at the getBrowserContent() line here:
BrowserContent browserContent = null;
try
{
browserContent = _renderingSession.getBrowserContent(connection, this, e);
<snip>
}
catch (RenderingException re)
{
EventLogger.logEvent(ID, (re + "").getBytes(), EventLogger.ERROR);
System.err.println(re);
}
返回的例外是：
net.rim.device.api.browser.field.RenderingException：IOException异常在连接
net.rim.device.api.browser.field.RenderingException: IOException in connection
我试过建设和使用与4.5.0和4.7.0组件包的模拟器，但它们都具有相同的症状。
I've tried building and using the Simulator with the 4.5.0 and 4.7.0 Component Packs, but they both have the same symptoms.
如果我推samples.cod文件到我的设备并启动它，我得到错误启动样本：模块'样品'尝试访问安全API。 presumably我需要签署样本code。与我的code签名密钥（这一点我有），这我不知道如何在Eclipse做的。
If I push the samples.cod file to my device and start it, I get "Error starting samples: Module 'samples' attempts to access a secure API". Presumably I would need to sign the sample code with my code signing keys (which I do have), which I am not sure how to do in Eclipse.
所以，我的问题是：
1）具有听谁说得到这个V4.5样本code的工作？我是否应该放弃对模拟器和使用的设备呢？
1) Has anybody actually got this V4.5 sample code working? Should I give up on the Simulator and use the device instead?
2）可用于显示一些简单的HTML数据这种做法V4.5的工作，我有吗？例如我可以使用本地主机URL，或者创建自定义的HttpConnection来提供数据？
2) Can this V4.5 approach work for displaying some simple HTML data that I have? e.g. can I use a localhost URL, or perhaps create a custom HttpConnection to serve up the data?
我要支持运行V4.5，V4.7和V5.0黑莓机型，如果在所有可能的。
I need to support BlackBerry models running V4.5, V4.7 and V5.0, if at all possible.
任何提示将AP preciated！
Any tips would be appreciated!
推荐答案
请确保您启动设备模拟器之前推出MDS模拟器。全部或大部分使用HTTP没有指定运输等都将使用默认的MDS运输，如果你没有那么MDS模拟器运行，则无法建立HTTP连接，这意味着样品。
Make sure that you launch the MDS simulator before launching the device simulator. All or most of the samples that use HTTP don't specify a transport and so will use the default MDS transport, which means if you don't have MDS simulator running then it won't be able to make an HTTP connection.
