Java android应用程序中没有internet连接

我使用的是mezzofanti OCR开源软件， 我想下载一种语言， 但上面说我没有网络连接， 我的设备上的internet连接已打开且正常工作， 我在android清单上有互联网权限

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

所以我不明白为什么它不起作用

您的错误消息不是告诉您没有internet，而是告诉您找不到给定的文件。您必须验证文件是否存在。

错误中的文件名为

http://www.itwizard.ro/mezzolang/languages.txtlanguages.txt

。您可能应该删除

languages.txt
