Image not Loading in Android Pie Version

I have implemented fresco library, It is working on all OS except Android Pie.
If I am adding android:usesCleartextTraffic="true" in manifest then ,Images are loading properly
But this will allow all http connection , which I suppose is not what we want.
Another way to overcome this problem is to make a network config file in which i have to allow domain and add that file in android Manifest. like this
android:networkSecurityConfig="@xml/network_security_config"

So kindly provide the domain which i have to include in that file or suggest me a better solution

PS: I have already include my domain in that file, and my app is working fine except loading image.
Sorry for my bad english :)
