+```
+This code defines an `ActivityTrackerMiddleware` class that inherits from `BaseHTTPMiddleware` from the Starlette library. The `dispatch` method is overridden to log the request method, URL path, and processing time for each incoming request.
+Here's a breakdown of the code:
+This middleware can be added to the FastAPI application by including it in the list of middleware instances when creating the application. For example:
+```python
+from fastapi import FastAPI
+from app.api.core.middleware.activity_tracker import ActivityTrackerMiddleware
+app = FastAPI()
+app.add_middleware(ActivityTrackerMiddleware)
+```
+With this middleware in place, each incoming request will be logged with its method, URL path, and processing time.
