I'm programming a basic app to share apk files between two devices the problem is when I extract an installed app base file (base.apk) from /data/app I get "App not installed" error when trying to install this apk file ... I even tried apps like ApkExtractor but I get the same error ... this problem only happened on android 10 , the app works file on android 6 .... any ideas why is this happening and how to fix it ??
