How to Fix a Unity Android App Bundle Too Big for the Play Store Limit

Google Play caps the size that downloads at install. A Unity game with lots of art and audio in the base module hits that ceiling. Play Asset Delivery splits content into packs that download separately, keeping the initial install small.

How to fix it

1. Identify optional content

Separate must-have-at-launch assets from content needed only later (later levels, high-res packs). The optional content is what moves into on-demand or fast-follow packs.

2. Configure asset packs

Use Unity's Play Asset Delivery support to create asset packs and assign content, choosing install-time for essentials and on-demand or fast-follow for the rest.

3. Fetch packs at runtime

Request on-demand packs via the delivery API before the content is needed, showing download progress, so players get a small initial install and stream the rest.

Catching the ones you can't reproduce

The hardest version of this to fix is the one you can't reproduce — it only happens on a player's hardware, OS, driver, or save state, under conditions that simply aren't present on your machine. A report that says “it crashed” or “it froze” gives you nothing to act on, so the bug survives release after release while quietly costing you players.

Automatic error capture closes that gap. Each failure arrives with its full stack trace, the device and OS, the build number, and a breadcrumb trail of what the player did right before it broke, so even a failure you have never seen becomes a specific, reproducible issue. Fold identical failures into one signature ranked by how many players each hits, and your worklist sorts itself worst-first instead of arriving as a stream of vague complaints.

This is where a tool like Bugnet earns its place. Its SDK captures every mobile error automatically with the full stack trace plus device, OS, memory, build, and game-state context, folds duplicates into one grouped issue with an occurrence count, and ties each to the build it first appeared on — so you fix the problem that hurts the most players first and confirm it is gone when its signature disappears from the next release.
