Click to expand... trust me - i did search and couldn't find any solution my app is basically a simple app nothing "problematic" it works for many years with many users so i'm really lost here as i can't understand where my problem is google play dashboard gives a list of libs that are causing the issue or not compatible - but these libs are not libs i added so i guess they are internal libs i've uploaded 2 screenshots in prev post with all libs i use on another lever a few of them, external, i can't find where to download the updated versions - can that be the solution?

mcqueccu Expert Licensed User Longtime User Dec 1, 2025 #10 check the date the 16kb alert was sent, if its older then it means it is resolved in your new build. I realised even if you update the new version of the app that support 16kb, the RED NOTICE at the top does not vanish, unless you delete it yourself Upvote 0

I have 2 libs that are known as not compatible with 16KB 0 SQLCipher and PDFium. Question #1 - why this info about these libs doesn't show up in bundle explorer? Question #2 - I have a phone Samsung S23+ with Android 16 which is on the list of the devises suggested by Google for testing in 16KB environment. And despite these 2 libs aren't compatible my app works fine on this phone. Upvote 0

mcqueccu Expert Licensed User Longtime User Dec 1, 2025 #14 So far as your Android 16 device and the play console isnt reporting any 16kb issue, then its solved. For SQLCipher you can use this one SqlCipher version 4.10.0 Hola, debido a los problemas que encontré con Google y SQLCipher, decidí actualizar la librería a la versión 4.10.0. Usé un envoltorio de Erel y ajusté las referencias a la nueva versión. Por favor, notifiquen cualquier error. Probé parte de la librería; el ámbito de prueba fue en Android 15... www.b4x.com Upvote 0
