Yes, of courses, the text is in French because I use a french google site ...
I translate the message :
1) This APK creates code and unused resources that are sent to users. You could reduce the size of your app with the Android App Bundle format. Because you are not optimizing your app for device configurations, it is larger than necessary for download and installation on users' devices. Large apps have lower install rates and take up space on users' devices.
2) This APK contains Java / Kotlin code which may be obfuscated. We recommend that you import an obfuscation file to make it easier to analyze and debug crashes and ANR errors. Find out more
Thanks
