Google has introduced ADB Wi-Fi 2.0, an updated version of Android Debug Bridge’s wireless connectivity system designed to make connections between Android devices and computers faster and more reliable.
Android Debug Bridge, or ADB, is primarily used by developers to communicate with Android devices, but it is also used by advanced users for tasks such as transferring large amounts of data, running tools such as scrcpy and accessing functions that are not available through the standard Android interface.
Google reworks ADB’s core components
Google has made changes to three key parts of the wireless ADB system.
The first is the ADB server. Previously, connections could be interrupted when network configurations changed or when an Android device was turned off.
Google has replaced the older multicast DNS (mDNS) stack to improve connection reliability.
The ADB daemon has also been updated. The new system can automatically disable wireless ADB connections when a computer and Android device are connected through an untrusted network.
Connections are re-enabled once both devices return to a trusted network, adding an extra security layer to wireless debugging.
Android Studio gets easier device discovery
Google has also improved wireless device discovery in Android Studio.
Once wireless debugging is enabled on an Android device, it should appear in Android Studio’s Device Manager, making it easier for developers to locate and connect compatible devices.
Google reports faster connections
Google says ADB Wi-Fi 2.0 delivers 66% faster connection speeds for 90% of connections, while automatic connection rates have increased by 32%.
The updated wireless ADB system can be used with Android phones, tablets, Wear OS watches and Android TV devices.
Google says the changes are intended to make wireless debugging more dependable while reducing the need for users and developers to reconnect devices manually.
