Field currentActivity or type signature not found

I am using unity 2019.4.24f1 and unity remote 5 app connected with USB.

var javaUnityPlayer = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
var currentActivity = javaUnityPlayer.GetStatic<AndroidJavaObject>("currentActivity");

This error is thrown from currentActivity line.

Exception: Field currentActivity or type signature  not found

Android plugin requires android device or emulator to set current activity.

In case anyone stuck with the same issue. The emulator & unity remote 5 app connected with USB didn't work at least. But creating a apk build & running it on the android device was successful.
