Waydroid is great but it creates some pointless default launcher apps that not everyone wants.
To combat this you can go into ./local/share/applications/ directory and delete the waydroid ones (except the default waydroid.desktop or you potentially wont be able to get into waydroid at all).
That can be annoying and time consuming, so why not do all of them or select ones as a script
create a UTLauncher-waydroid-app-remover.sh script and ensure it has;
chmod +x to allow it to be executed.
Don't forget to make sure you have mounted your system to rw
sudo mount -o remount,rw /
Contents of the script;
#Ubuntu Touch Launcher Android App Remover Script
cd ~/.local/share/applications
rm waydroid.com.android.calculator2.desktop #AOSP calculator
rm waydroid.com.android.camera2.desktop #AOSP camera
rm waydroid.com.android.contacts.desktop #AOSP contacts
rm waydroid.com.android.deskclock.desktop #AOSP clock
rm waydroid.com.android.documentsui.desktop #AOSP file browser application
rm waydroid.com.android.email.desktop #AOSP email
rm waydroid.com.android.gallery3d.desktop #AOSP gallery
rm waydroid.com.android.inputmethod.latin.desktop #AOSP keyboard
rm waydroid.com.android.settings.desktop #AOSP android settings
rm waydroid.org.lineageos.eleven.desktop #lineage music player
rm waydroid.org.lineageos.etar.desktop #lineage calendar
rm waydroid.org.lineageos.jelly.desktop #lineage web browser
rm waydroid.org.lineageos.recorder.desktop #lineage recording application
exit
That there will delete everything.. you will want to most likely modify it to suit your needs which can be done by placing a # at the start of the line or deleting that particular line altogether. You can add further ones to it as well if you have a typical setup in waydroid so if you need to reinstall waydroid for whatever reason you have a script ready to run.
These commands are device agnostic and should work on any UT device... I only have a Pixel 3a XL to test these on.
