问题标签 [google-talk]

我正在 GAE 上使用 python 编写应用程序。我想既然我使用谷歌登录作为我的用户的身份验证，为什么我不能使用每个用户的谷歌聊天图片作为他们的用户画像？但是我还没有找到访问该信息的方法。也许我使用 facebook api 的时间太长了，但是有什么方法可以访问这些信息吗？

克里斯

我正在尝试创建一个程序来显示我的 Gtalk 的状态（在线/离线）。

我可以找到 Status View 2 类，但如何找到其中的文本。

这是我的代码。

AppBrain has a fantastic new app that lets you automatically install applications on your phone using your web browser. Similar to the Chrome push. In their case, they are using it to let you install apps without a prompt directly on the phone. Engadget has a good video demonstrating their system.

My question is: What mechanism are they using to avoid asking for a prompt on the phone and to do the installation directly?

The reason I'm asking is that have a couple hundred android phones that run some custom software, the users have to manually update the software by clicking through the install process. And ideally I'd prefer to be able to do push updates without having to prompt people (in exchange for a free phone+service you have to run the software, so 'you shouldn't do that' doesn't invalidate the question of how do you do that). The biggest problems are that if you're doing rapid development/testing it's a pain to get everyone up to the right versions and it's hassle for people.

What AppBrian does sounds like a perfect fix to this problem, but how does it work? The only permission the AppBrain fast installer asks for is access to your accounts and network access. Now, there was the interesting development about Jon Oberheide's REMOVE_ASSET and INSTALL_ASSET which he says uses the GTalk service to imitate prompt-less installs. The interesting this is that AppBrian's FastWeb installer works on a 2.01 Droid but does not work on a 2.2 Nexus One (maybe one of the last round of Froyo updates disables AppBrain's access to the INSTALL_ASSET intent). http://jon.oberheide.org/blog/2010/06/25/remote-kill-and-install-on-google-android/

Can anyone shed any light on this? I know auto update is coming for the Market but I'm not sure if this would be a usable workaround. I'm fine with saying 'you need to click to install this once', but having hundreds of people waste their time clicking 'ok' is a waste.

I personally think that this is something Google should support for Enterprise users in the future with the Device Administrator features. If I went with Android and could easily stage and keep people up to date with apps it wold be pretty useful.

我正在寻找一种解决方案，可以从我的 android 应用程序向我的所有 Google 联系人发送多播（文本）消息。有没有办法用 GTalk 应用程序（意图）来做到这一点，还是我必须使用我自己的 xmpp 实现？除了 gtalk 捎带之外，还有什么合适的解决方案/框架的建议吗？谢谢

我想为 gtalk 创建浏览器小部件。我需要了解 XMPP 及其对 javascript 的支持。任何人都可以在这个过程中指导我。提前致谢。

如何使用 smack java 库向 gtalk 联系人发送邀请？

我们计划使用 gtalk 来创建聊天机器人。我的问题是 gtalk 是否对联系人数量或每分钟/小时/天的消息数量有任何限制？

我想为 gtalk 开发一个简单的插件，这可能吗？是否有显示如何做到这一点的 api 或教程？

谢谢

I'm currently writing an Android application that should be able to receive push notifications from another application hosted in Google's App Engine. Since I can't use sockets in GAE, I though maybe using XMPP over GTalk server would solve my problem. But that way the Android Application would be connected to the users Gtalk account and thus showing the user as being online, when in reality the user is not.

Any way of achieving this kind of communication without showing the user as being online, and without asking the user to create a separate account?

Or any free push notification alternatives?

EDIT: I'm targeting 1.5+ Android devices so C2DM isn't an option.

Thanks!

我正在尝试通过 XMPP 服务器使用 SMACK API 连接到 gmail。但得到

错误：使用机制 PLAIN 的 SASL 身份验证失败

你可以检查一下代码。我只从网上得到

我检查了 smack 调试窗口。它在 XML 中说：

< 无效的身份验证 />

我已经在 gmail 上拥有帐户，并且我的 gtalk 也在运行。
