I am using Android emulator (Pixel 9) on Android Studio (2025.1.2 Patch 2).
Every time I focus on text field, I see the floating button group (see the following image).
Here are questions:
This toolbar is a feature of the emulator's version of Gboard ("Write in text fields").
To remove/disable it:
1. Go to Gboard Settings in the emulator.
2. Find the option Write in text fields (sometimes listed under "Stylus").
3. Turn off Use stylus to write in text fields.
