Set ad position after the data is loaded

android

#1

Hello
I’ve found the ad position could be set both on Server side (mopub setting UI) and Client side (code).
(https://github.com/mopub/mopub-android-sdk/wiki/Native-Ads-Integration)
Is there any way to change the ad position after my mopub adapter is created?
Can I set moPubClientPositioning.addFixedPosition(position); after my mopub adapter is created.
Because there is some data I need to get from server side.
I only can decide the ad position after data is loaded.
What should I do ?
Thanks
