Configuring ADB Environment Variables

To enable the adb command-line tool, add the Android SDK platform-tools directory to the system PATH.

1. Determine the SDK installation path. In Android Studio, navigate to Preferences > Appearance & Behavior > System Settings > Android SDK. The SDK location is displayed at the top of the window.

2. Open a terminal and modify the shell profile configuration. For bash, edit ~/.bash_profile:

   # Append SDK paths to PATH
   echo 'export PATH=$PATH:~/Library/Android/sdk/platform-tools' >> ~/.bash_profile
   echo 'export PATH=$PATH:~/Library/Android/sdk/tools' >> ~/.bash_profile
   

3. Apply the changes by sourcing the profile:

   source ~/.bash_profile
   

4. Verify the installation by checking the adb version:

   adb version
   

Adding Device Vendor ID

Register the device's vendor identifier to allow ADB to recognize it.

1. Connect the Android device via USB.

2. List connected USB devices and identify the vendor ID:

   system_profiler SPUSBDataType | grep -A 10 "Manufacturer: YourDeviceManufacturer"
   

   Look for a line containing Vendor ID. Example output snippet:

         Vendor ID: 0x05e4  (Samsung Electronics Co., Ltd.)
   

3. Create or update the ADB USB initialization file:

   mkdir -p ~/.android
   echo "0x05e4" >> ~/.android/adb_usb.ini
   

Restarting the ADB Daemon

Restart the ADB server to apply the new configuration:

adb kill-server && adb start-server

Enabling USB Debugging

On the Android device, enable developer options (typically by tapping the build number seven times in Settings > About phone). Then, in Developer options, toggle on USB debugging.

Running an Application

In Android Studio, select the physical device from the deployment target menu and execute the run configuration.
