Quick answer: Build and include arm64-v8a native libraries, ensure every native dependency provides a 64-bit version, and ship an App Bundle with the required architectures.

A 64-bit rejection is a missing arm64 native library. Including it fixes it. Here is how.

How to fix it

1. Include arm64 libraries

Build your native code for arm64-v8a and include it. A build with only 32-bit (armeabi) native libraries fails Google Play's 64-bit requirement.

2. Check native dependencies

Every native plugin and SDK must provide a 64-bit version. One dependency that ships only 32-bit blocks compliance. Update or replace any that lack arm64.

3. Ship an App Bundle with the architectures

Publish an App Bundle including the required architectures so Play delivers the right native libraries per device, and verify the upload reports 64-bit support.

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.

Reproduce it once with full context and the fix writes itself. The hunt is the expensive part.
