用android模拟器，调试app，app无法访问网络。

报下面的错误 

E/netmgr: Failed to open QEMU pipe 'qemud:network': Invalid argument

E/netmgr: WifiForwarder unable to open QEMU pipe: Invalid argument

E/memtrack: Couldn't load memtrack module

可能需要mac网络DNS配置

可能需要设置下面

This issue was occurring in Android 9.0 for me and I fixed it by adding android:usesCleartextTraffic="true" inside application tag.

<application
    ..
    android:usesCleartextTraffic="true"
