For example, you can deploy your debuggable app to multiple remote devices without physically connecting your device via USB.

See the guide to debugging a Wear OS app for more information.Īndroid 11 and higher supports deploying and debugging your app wirelessly from your workstation using Android Debug Bridge (adb). Note: The instructions below do not apply to Wear devices running Android 11. Connect to a device over Wi-Fi (Android 11+) This security mechanism protects user devices because it ensures that USB debugging and other adb commands cannot be executed unless you’re able to unlock the device and acknowledge the dialog.įor more information about connecting to a device over USB, read Run Apps on a Hardware Device. Note: When you connect a device running Android 4.2.2 or higher, the system shows a dialog asking whether to accept an RSA key that allows debugging through this computer.
If connected, you’ll see the device name listed as a “device.” You can verify that your device is connected by executing adb devices from the android_sdk/platform-tools/ directory. You can now connect your device with USB. On some devices, the Developer options screen might be located or named differently. Return to the previous screen to find Developer options at the bottom. To make it visible, go to Settings > About phone and tap Build number seven times. On Android 4.2 and higher, the Developer options screen is hidden by default. To use adb with a device connected over Wi-Fi, see Connect to a device over Wi-Fi. To use adb with a device connected over USB, you must enable USB debugging in the device system settings, under Developer options. Connect to a device over Wi-Fi (Android 10 and lower).Check if your workstation and device meet the prerequisites.Connect to a device over Wi-Fi (Android 11+).Cách thay đổi số điện thoại và email đăng ký tài khoản Facebook.Because the server manages connections to devices and handles commands from multiple adb clients, you can control any device from any client (or from a script). Once the server has set up connections to all devices, you can use adb commands to access those devices. For example:Įmulator 1, console: 5554 Emulator 1, adb: 5555 Emulator 2, console: 5556 Emulator 2, adb: 5557 and so on…Īs shown, the emulator connected to adb on port 5555 is the same as the emulator whose console listens on port 5554. Note that each emulator uses a pair of sequential ports - an even-numbered port for console connections and an odd-numbered port for adb connections.
Where the server finds an adb daemon (adbd), it sets up a connection to that port. It locates emulators by scanning odd-numbered ports in the range 5555 to 5585, the range used by the first 16 emulators. The server then sets up connections to all running devices. When the server starts, it binds to local TCP port 5037 and listens for commands sent from adb clients-all adb clients use port 5037 to communicate with the adb server.
If there isn’t, it starts the server process. When you start an adb client, the client first checks whether there is an adb server process already running.
