title: Class App\Http\Controllers\ does not exist
body: <p>This is my Route: </p>
  
  <pre><code> Route::get('/hello', '@HomeController@index');
  </code></pre>
  
  <p>This is my HomeController </p>
  
  <pre><code>namespace App\Http\Controllers;
  use app\Requests;
  use Illuminate\Http\Requests;
  use Spatie\Activitylog\Models\Activity;
  use Illuminate\Database\Eloquent\Model;  
  use Illuminate\Support\Facades\Auth;
  
  class HomeController extends Controller {
  
     public function index() {
      $lastActivity = Spatie\Activitylog\Models\Activity::all();
      return view('activity'), compact('lastActivity'));
     }
  
  }
  </code></pre>
  
  <p>But I keep on getting an error message:</p>
  
  <pre><code> ReflectionException in Route.php line 280:
   Class App\Http\Controllers\ does not exist
  </code></pre>
  
  <p>What can I do? Thanks. </p>
