adb.exe: no devices/emulators found

By: Gren in Android Tutorials on 2023年04月03日 [フレーム]

The error message "adb.exe: no devices/emulators found" means that ADB (Android Debug Bridge) is not able to detect any connected Android devices or emulators. Here are some possible solutions:

  1. Check the USB connection: If you are trying to connect an Android device to your computer via USB, make sure that the USB cable is securely connected and that the device is in USB debugging mode. To enable USB debugging, go to the "Developer options" in the device's settings and toggle the "USB debugging" option.

  2. Check the emulator settings: If you are trying to connect to an Android emulator, make sure that the emulator is running and that it is configured to allow ADB connections. You can check this by opening the emulator and going to its "Settings" > "Developer options" menu, and making sure that "USB debugging" is enabled.

  3. Restart ADB: Sometimes, simply restarting ADB can help resolve connection issues. To do this, open a command prompt or terminal window and run the command "adb kill-server" followed by "adb start-server".

  4. Check ADB version: Ensure that you have the latest version of ADB installed. You can download the latest version of ADB from the Android SDK platform tools website.

  5. Check device drivers: If you are using a Windows PC, you may need to install the device drivers for your Android device. You can usually download these from the manufacturer's website.

  6. Try using a different USB port: Sometimes, the USB port you are using can cause connection issues. Try connecting your device to a different USB port on your computer.

  7. Try using a different cable: Sometimes, the USB cable you are using can cause connection issues. Try using a different USB cable to connect your device to your computer.

  8. Try using a different computer: If none of the above solutions work, try connecting your Android device to a different computer to see if the issue is with your computer's USB ports or ADB installation.
