并已使用Android Studio 4.0构建了签名的apk(启用了生产)，一旦我在设备上尝试了apk，它与Android 6.0, 7.0, 8.0应用程序的正常工作是从服务器获取数据.但是当我在Android 10.0上尝试访问它时，它无法访问互联网.

And have build the signed apk (production enabled) using Android studio 4.0, and once i tried the apk on devices, it works fine with Android 6.0, 7.0, 8.0 application is fetching data from server. But when i try to it on Android 10.0 it cannot access internet.

有什么帮助吗?谢谢.

推荐答案

默认情况下，Android 9和更高版本禁用HTTP连接，因此，如果要允许http连接，可以将android:usesCleartextTraffic="true"添加到application标签中>

Android 9 and newer disable http connections by default, so if you want to allow http connections you can add android:usesCleartextTraffic="true" to the application tag in AndroidManifest.xml

或者，如果您不想允许所有http通信，而只允许几个URL，请检查security-config文档:

Or if you don't want to allow all http traffic, but just a few urls, check security-config docs: https://developer.android.com/training/articles/security-config#CleartextTrafficPermitted
