Android Emulator

Keep the app you are building and the device it runs on side by side: the emulator screen lives in a thread panel, and agents drive the same device from the CLI.

What you get

• Live H.264 screen of an emulator on any of your bb hosts, with touch, scroll, keyboard and system buttons.
• Unicode text paste into the focused field and clipboard sync in both directions.
• Environment checks for the Android SDK, ADB, emulator, hardware acceleration and AVDs, each with a hint when it fails.
• Start an existing AVD headless and stop a running emulator.
• Agent commands: bb android-emulator hosts, list, start, stop, key and paste.
• Interface in 12 languages.

How it works

The plugin runs on the Android host inside the bb host worker. It talks to the emulator through ADB and the bundled scrcpy-server 3.3.3, and the browser decodes the stream with WebCodecs. Each viewer connection needs a one-time token and the panel's exact origin. You pick the host in the panel; one device stream is active per host.

Connection

• BB network (default) streams through bb connect shared ports and needs bb opened at getbb.app.
• LAN / VPN connects the browser straight to the host over plain ws://, for trusted networks only. Chromium asks for local network access.

Requirements

• A bb host on Windows or Linux with the Android SDK (platform-tools, emulator), at least one AVD and working hardware acceleration (WHPX/AEHD or KVM). macOS is untested.
• A browser with WebCodecs H.264 support.

The plugin does not install the SDK, system images or hypervisors, and does not create or change AVDs.
