I am writing an app to import photos from Gallery/Albums, so I want to pre-create some photo gallery albums and put some photos into them.
Download
Start Android Emultor (I am using API 30).
Access Settings within Android Emulator: 1) Swipe up from bottom to access App list and click Settings or 2) Swipe down from top, expand the icon list and click on Settngs icon.
Select Storage -> Internal shared storage -> Photos & Videos -> Images
Drag some images from your desktop into the emulator. The images and Download gallery/album will take a while to be created.
Pictures
Start Android Emultor.
Start Camera App (Swipe up from bottom to access App list and click Camera)
Take some photos in the virtual living room (hold down ALT and use the mouse to rotate around the room).
The taken photos will be stored in Pictures gallery/album.
