🐛 Bug Report

As described in https://developer.android.com/guide/practices/page-sizes, Android 15 adds support for devices that use a 16KB page size. When running an app set up with Flipper on one of these devices, the following crash occurs:

We are seeing similar behavior, when going through the steps described here, thelibflipper.so is being marked as UNALIGNED

+1. I think the flipper library owners need to do something similar to how things were handled here

Solution:

Yes, we need build again to support 16kb page size

Android 15 was released to AOSP yesterday https://android-developers.googleblog.com/2024/09/android-15-is-released-to-aosp.html

Do you expect this to be prioritized any time soon?

Thanks for your work on open source software.

Edit: There is a release date now https://www.androidheadlines.com/exclusive-android-15-ota-google-pixel

Any workaround?

I think we need to make sure there are updates to the child dependencies and then create a PR with the updates

Do we know which child libraries need to be updated?
