在清单文件中授予该权限。该权限如何
<uses-permission android:name="android.permission.INTERNET" />
我确实给了许可,你可以清理项目,然后再试一次。这可能只有两种可能,一种是没有internet权限,另一种是url连接可能会被拒绝,因为它无法访问。请从测试应用程序的另一个浏览器中尝试该url。是否可以从其他来源连接到计算机?因为目标似乎不接受连接。这并不能提供问题的答案。若要评论或要求作者澄清,请在他们的帖子下方留下评论-你可以随时在自己的帖子上发表评论,一旦你有足够的评论,你就可以发表评论了。是的,对不起……我只是想发表评论,但我不能,因为声誉问题
