Questions and Answers

Q1: Due to the Package visibility in Android 11, I can't get a list of all installed apps, not even directly querying with the package name..
A: See here: The limited package visibility reduces the number of apps that appear to be installed on a device, from your app's perspective. You might want to add the permission QUERY_ALL_PACKAGES into the manifest
Note: If you publish your app on Google Play, your app's use of this permission is subject to approval based on an upcoming policy. To add that permission into the manifest, you can use the extension tsf.queryallpackages.aix. Thank you anonwins.
