如果您设置了代理服务器设置为Android设备，难道他们对设备，包括浏览器上的所有应用程序？或者，它们只适用于浏览器？

我想问的原因是，当你去改变在Android设备上的代理服务器设置有这个消息，这是困惑我：

 由浏览器的HTTP代理使用，但不得使用其他应用程序
 

解决方案

没有，他们没有在全球范围，无根应用是没有办法来强制将所有应用程序使用的代理服务器。您发现该邮件的措辞这种方式的原因是，它是由应用程序的创建者尊重代理设置，并使用它们或做错误的事情，而忽略他们。

如果你碰巧扎根，您可以使用这个程序这将代理设置适用于所有的应用程序和活动。

究其原因，这不是默认的行为，是因为它可以present一定的安全隐患。如果所有的交通可能被重定向，用户可以有他们的所有流量通过探听他们一些不好的代理服务器去，使他们默认为只允许应用程序使用代理服务器，如果他们明确地提出要求。

If you set up proxy settings for an android device, do they apply to all apps on the device including the browser? Or do they only apply to the browser?

The reason I ask is that when you go to change the proxy settings on an android device there is this message, and it is confusing me:

"HTTP proxy use by browser but may not be used by other applications"

No, they do not apply globally and without root there is no way to force a proxy to be used by all applications. The reason the message you found is worded that way is that it is up to the app creator to respect the proxy settings and use them or do the wrong thing and ignore them.

If you happen to be rooted, you can use this app which will apply the proxy settings to all apps and activities.

The reason that this is not the default behavior is because it could present some security risks. If all traffic could be redirected, users could have all of their traffic be going through some bad proxy server that snoops on them so they default to only allowing apps to use proxy if they explicitly ask for it.
