Google has released Android 17 Beta 3, featuring app bubbles, which enhance multitasking by allowing users to keep applications floating on their screens for quick access. Users can create app bubbles by long-pressing any app icon and selecting the "bubble" option, which opens the app in a small floating window that can be minimized into a bubble. Multiple bubbles can be stacked, and tapping a stack expands it for easy management. Users can remove bubbles by dragging them to an "X" button, and on foldable devices, bubbles can be arranged in a taskbar-style layout. The app bubbles feature allows for various multitasking scenarios, such as responding to messages without switching apps, keeping notes open while shopping, watching videos while taking notes, checking maps during chats, planning trips without app switching, and copying information easily between applications.
