Android Physical Devices

Warning

This method involves ADB command-line usage, has lower stability, and still requires computer connection. Not recommended for beginners.

Note

  1. Please also refer to Connection Settings.
  2. Starting from Android 10, Minitouch is no longer available when SELinux is in Enforcing mode. Please switch to other touch modes, or temporarily switch SELinux to Permissive mode.
  3. Due to the extreme complexity of the Android ecosystem, try changing the Connection Configuration in MAA Settings - Connection Settings to General Mode, Compatibility Mode, 2nd Resolution, or General Mode (Block Exception Output) until one mode works properly.
  4. Since MAA only supports 16:9 aspect ratios, devices with non-16:9 or 9:16 screen ratios (including most modern devices) need to have their resolution forcibly changed. If your device's native screen ratio is 16:9 or 9:16, you can skip the Change Resolution section.
  5. Switch your device's navigation method to something other than Full Screen Gestures, such as Classic Navigation Keys, to avoid accidental operations.
  6. Please set the Notched Screen UI Adaptation option in the game settings to 0 to avoid task errors.

Tips

Typical 16:9 resolutions include 3840x2160 (4K), 2560x1440 (2K), 1920x1080 (1080P), and 1280x720 (720P).

Download and Run ADB Debug Tool to Connect Device

  1. Download ADB and extract it.

  2. Open the extracted folder, clear the address bar, type cmd, and press Enter.

  3. In the command prompt window that appears, type adb. If you see extensive help text, the command ran successfully.

  4. Enable USB Debugging on your phone. The process varies by manufacturer, so use a search engine to find instructions. Manufacturers may provide additional USB debugging options, such as MIUI's USB Installation and USB Debugging (Security Settings) - enable these too.

  5. Connect your phone to the computer with a data cable and enter the following command in the command prompt:

    adb devices

  • When executed successfully, it will show connected USB debugging devices.

    • Example of a successful connection:

      List of devices attached
VFNDU1682100xxxx        device

    • The alphanumeric combination before device is the device serial number, which is also your MAA Connection Address.

  • Modern Android devices require authorization on the device itself. Without authorization, you'll see:

    List of devices attached
VFNDU1682100xxxx        unauthorized

  • If you consistently get "unauthorized" or "offline" status, restart both your device and computer. If that doesn't help, delete the .android folder in your user's personal directory and try again after restarting. Use search to find the exact location.

Change Resolution

Tips

Mobile screen resolution is specified as short edge × long edge, not long edge × short edge as with computer monitors. Determine the appropriate values for your specific device.

  • If you only have one device in your device list, run these commands to change/restore resolution:

    # View current resolution
adb shell wm size
# Restore default resolution
adb shell wm size reset

# Change to 720p
adb shell wm size 720x1280
# Change to 1080p
adb shell wm size 1080x1920

  • If you have multiple devices, add the parameter -s <target device serial number> between adb and shell:

    # View current resolution
adb -s VFNDU1682100xxxx shell wm size
# Restore default resolution
adb -s VFNDU1682100xxxx shell wm size reset

# Change to 720p
adb -s VFNDU1682100xxxx shell wm size 720x1280
# Change to 1080p
adb -s VFNDU1682100xxxx shell wm size 1080x1920

  • Some apps with irregular designs may still have layout issues after resolution restoration. Usually, restarting the app or device resolves this.

Warning

Strongly recommended to restore the default resolution before restarting your device. Otherwise, depending on your device, unpredictable consequences may occur, including layout chaos, touch misalignment, app crashes, inability to unlock, etc.

Automate Resolution Changes

  1. Create two text files in the MAA directory with the following content:

    # Adjust resolution to 1080p
adb -s <target device serial number> shell wm size 1080x1920
# Lower screen brightness (optional)
adb -s <target device serial number> shell settings put system screen_brightness 1
    # Restore resolution
adb -s <target device serial number> shell wm size reset
# Increase screen brightness (optional)
adb -s <target device serial number> shell settings put system screen_brightness 20
# Return to home screen (optional)
adb -s <target device serial number> shell input keyevent 3
# Lock screen (optional)
adb -s <target device serial number> shell input keyevent 26

  2. Rename the first file to startup.bat and the second to finish.bat.

    • If no confirmation dialog appears when changing the extension and the file icon doesn't change, search for "How to show file extensions in Windows."

  3. In MAA's Settings - Connection Settings, set Start Script to startup.bat and End Script to finish.bat.

Connect to MAA

Wired Connection

Tips

Wired connections don't need IP addresses or ports - just the device serial number from adb devices.

  1. Enter the target device serial number from above into MAA's Settings - Connection Settings - Connection Address.
  2. Link Start!

Wireless Connection

  • Ensure your device and computer are on the same network and can communicate with each other. Router settings like AP Isolation or Guest Network can block device communication - check your router documentation.
  • Wireless debugging is disabled after device restart and must be re-enabled.

Using adb tcpip for Wireless Debugging

  1. In the command prompt, enable wireless debugging:

    adb tcpip 5555
# Add -s parameter to specify the serial number if multiple devices are connected

  2. Find your device's IP address:

    • Go to your phone's Settings - Wi-Fi, tap the connected network to view the IP address.
    • The location varies by manufacturer - search for instructions if needed.

  3. Enter <IP>:5555 in MAA's Settings - Connection Settings - Connection Address, e.g., 192.168.1.2:5555.

  4. Link Start!

Using adb pair for Wireless Debugging

Tips

adb pair wireless pairing (available in Android 11 and later via Developer Options) allows connection without a physical USB connection, unlike adb tcpip.

  1. On your phone, go to Developer Options, tap Wireless Debugging and enable it. Tap Pair device with pairing code and keep the popup open until pairing completes.

  2. Complete the pairing:

    1. In the command prompt, type adb pair <IP address and port shown in the device popup> and press Enter.
    2. Enter the six-digit pairing code from the device popup and press Enter.
    3. When you see Successfully paired to <IP:port>, the device popup will close automatically, and your computer's name will appear in the paired devices list.

  3. Enter the IP address and port shown on your device screen into MAA's Settings - Connection Settings - Connection Address, e.g., 192.168.1.2:11451. This is different from the address used for pairing.

  4. Link Start!

Using Root to Enable Wireless ADB

If you have access to root, why do you need to read this document

  1. Download, install WADB and grant it root privileges. 2.
  2. Open WADB and start wireless adb. 3.
  3. Put the IP address and port provided by WADB into MAA Settings - Connection - Connection Address, such as 192.168.1.2:5555.
  4. Link Start!
