     - Add a new system variable with the name `ANDROID_HOME` and value as the path to your SDK directory (usually `C:\Users\[Username]\AppData\Local\Android\Sdk`).
     - Edit the `Path` variable and add `%ANDROID_HOME%\platform-tools`.
   - **macOS/Linux:**
     - Open your shell profile file (`.bash_profile`, `.zshrc`, `.bashrc`, etc.).
     - Add `export ANDROID_HOME=$HOME/Library/Android/sdk` and `export PATH=$PATH:$ANDROID_HOME/platform-tools`.

### Step 2: Enable USB Debugging on Your Android Device

### Step 6: Capture Logs Using ADB Logcat

1. **Start Capturing Logs:**
   - Type `adb logcat` and press Enter to start displaying log output.
   - To save the log output to a file, type `adb logcat -v time > filename.txt` and press Enter. Replace `filename.txt` with the desired file name.

### Additional Notes
