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

WARN / System.err的（223）：java.net.SocketException异常：权限被拒绝（也许缺少INTERNET权限）

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

我已经加入android.Manifest.permission到我的应用程序，但它仍然给了同样的异常。

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

推荐答案

假如，你没有从你的 LogCat中错误描述设置权限，这是我的内容，我 AndroidMainfest.xml 文件，该文件有访问互联网：

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

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

除此之外，你应该罚款从互联网上下载文件。

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