.NET MAUI: How Do I Deploy and Debug on an Android Device via USB in VS2022?

Below is how you can deploy your .NET MAUI app directly to your mobile device via USB:

---

Prerequisites

• Developer Settings: Make sure your phone has developer mode enabled and USB debugging turned on.

• Device Drivers: Verify that you have the appropriate USB drivers installed for your phone.

• ADB Configuration: Confirm that your device appears when you run the command:

  BASHCopied
  adb devices

  This ensures that ADB (Android Debug Bridge) recognizes your device.

Deploying from Visual Studio 2022

1. Connect Your Device:
   Plug your mobile phone into your development PC via USB.

2. Check the Device Dropdown:
   In Visual Studio 2022, locate the target device dropdown on the toolbar (usually next to the Run/Debug button).
   If your device is properly detected, it should appear in this list — often labeled as something like "Google Android Device" or similar.

3. Select the Device:
   Choose your connected mobile device from the dropdown instead of an emulator or the local machine.

4. Run the Application:
   Press F5 or click the Debug button. Visual Studio will then build your .NET MAUI app and deploy it to the mobile device.

Clarifications

• Connected Device vs. Emulator:
  An app in development can indeed be deployed to and run on a connected mobile device. This is a common practice for testing on real hardware.

• Deployment Target:
  When you select your physical device from the dropdown, Visual Studio is instructed to build and push the app directly to that device.

By following these steps and confirming that your device is recognized (via ADB and the Visual Studio dropdown), you can develop, debug, and run your .NET MAUI app directly on your mobile phone.
