According to unreal docs from Google Play Asset Delivery Reference | Unreal Engine Documentation
You can only have one Install-Time and one Fast-Follow asset pack per project.
However , there’s no such limit on count of Fast-Follow asset pack from Google docs Android 开发者 | Android Developers
Download size limits
Asset packs are ideal for large games due to their increased size limits:
1.The download size limit for each fast-follow and on-demand asset pack is 512 MB.
2.The total download size limit for all install-time asset packs combined is 1 GB.
3.The total download size limit for all asset packs in an Android App Bundle is 2 GB.
4.You can use up to 50 asset packs in an Android App Bundle.
So, what’s the truth? How many Fast-Follow asset packs can I have within Unreal?
My android app bundle might be near 2GB but currently I do NOT want any on-demand asset packs. Is it possible?
