After removing bevy-inspector-egui dependency, the apk is built without any trouble.

[jakobhellermann]

Arboard is a dependency of bevy_egui https://github.com/mvlabat/bevy_egui/blob/84424bd547afdf5730deb356bcff6e99ad660fdb/Cargo.toml#L33 so it's probably best to open an issue there.

[agjini]

Ok, good point.

An issue is already open on the subject on bevy_egui. So I close it on bevy inspector
