如何向应用程序添加清单权限? [英] How to add manifest permission to an application?

问题描述

我试图在 Android 中使用 HttpURLConnection 访问 HTTP 链接以下载文件，但我在 LogCat 中收到此警告:

I am trying to access HTTP link using HttpURLConnection in Android to download a file, but I am getting this warning in LogCat:

WARN/System.err(223): java.net.SocketException: 权限被拒绝(可能缺少 INTERNET 权限)

WARN/System.err(223): java.net.SocketException: Permission denied (maybe missing INTERNET permission)

我已将 android.Manifest.permission 添加到我的应用程序中，但它仍然给出相同的异常.

I have added android.Manifest.permission to my application but it's still giving the same exception.

推荐答案

假设您没有根据 LogCat 错误描述设置权限，这里是我的 AndroidManifest.xml 可以访问互联网的文件:

Assuming you do not have permissions set from your LogCat error description, here is my contents for my AndroidManifest.xml file that has access to the internet:

<manifest xlmns:android...>
 ...
 <uses-permission android:name="android.permission.INTERNET" />
 <application ...
</manifest>

除此之外，您应该可以从 Internet 下载文件.

Other than that, you should be fine to download a file from the internet.
