How To Reproduce

1. #!/usr/bin/env sh
   settings put global enable_freeform_support 1 && \
   settings put secure force_resizable_activities 1 && \
   curl https://github.com/farmerbb/Taskbar/releases/download/207/Taskbar-6.2.2.apk && \
   pm install ./Taskbar-6.2.2.apk && \
   adb shell monkey -p com.farmerbb.taskbar 1

2. At cmd activity start --user 0 -a android.intent.action.VIEW -n com.farmerbb.taskbar/com.farmerbb.taskbar.activity.MainActivity -f 0 com.farmerbb.taskbar, apply checked="true" to resource-id="com.farmerbb.taskbar:id/the_switch":

   #!/usr/bin/env bash
   adb exec-out uiautomator dump /dev/tty \
   | sed 's/></>\n</g' \
   | awk '
     /class="android.widget.Switch"/ &&
     /resource-id="com.farmerbb.taskbar:id\/the_switch"/ &&
     /clickable="true"/ &&
     match($0, /bounds="\[([0-9]+),([0-9]+)\]\[([0-9]+),([0-9]+)\]"/, b) {
   
       cx = int((b[1] + b[3]) / 2)
       cy = int((b[2] + b[4]) / 2)
   
       system("adb shell input tap " cx " " cy)
       exit
     }
   '

   ⁷

3. Access "Freeform Mode":

   #!/usr/bin/env bash
   adb exec-out uiautomator dump /dev/tty \
   | sed 's/></>\n</g' \
   | awk '
     /class="android.widget.TextView"/ &&
     /resource-id="android:id\/title"/ &&
     /text="Freeform mode"/ &&
     match($0, /bounds="\[([0-9]+),([0-9]+)\]\[([0-9]+),([0-9]+)\]"/, b) {
   
       cx = int((b[1] + b[3]) / 2)
       cy = int((b[2] + b[4]) / 2)
   
       system("adb shell input tap " cx " " cy)
       exit
     }
   '

   ⁷

4. Enable "Freeform window support":

   #!/usr/bin/env bash
   adb exec-out uiautomator dump /dev/tty \
   | sed 's/></>\n</g' \
   | awk '
     /class="android.widget.TextView"/ &&
     /resource-id="android:id\/title"/ &&
     /text="Freeform window support"/ &&
     match($0, /bounds="\[([0-9]+),([0-9]+)\]\[([0-9]+),([0-9]+)\]"/, b) {
   
       cx = int((b[1] + b[3]) / 2)
       cy = int((b[2] + b[4]) / 2)
   
       system("adb shell input tap " cx " " cy)
       exit
     }
   '

   ⁷

5. Invoke an application via Taskbar's overlay.

The freeform windows used to be resizeable. I can't resize them anymore. Why?

[RokeJulianLockhart]

@nikos2wheels, I presume that it is a deficiency in AOSP 16, considering that it persists in a Canary VM, so one of us should, probably, report it at issuetracker.google.com/issues/new?component=190923&template=841312.¹² If so, it's extraordinarily incompetent.

However, because I've been unable to invoke them outside this application, I don't know whether my assessment is accurate. I've been waiting for this to be closed as an upstream bug, and, then, AOSP 17, to confirm whether it's deliberate.
