I've been following 3DR Dronekit-Android step-by-step project to create a mission planner app on Android Studio. I am stuck on creating a method for connecting via UDP.

extraParams.putInt(ConnectionType.EXTRA_UDP_SERVER_PORT, DEFAULT_UDP_PORT);
ConnectionParameter connectionParameter = new ConnectionParameter(ConnectionType.TYPE_UDP,extraParams, null);
drone.connect(connectionParameter);

I get an error message on ConnectionParameter as below

ConnectionParameter(int, android.os.Bundle, androind.net.Uri)' has private access in 'com.o3dr.services.android.lib.drone.connection.ConnectionParameter'

What are the arguments needed for ConnectionParameter? Is there any other way for me to find out required parameters in java libraries?

This is because the library has been changed, now, it follows the Singleton design pattern.

You don't need to create a new ConnectionParameter but to directly call the static method newUsbConnection() or newUdpConnection() in the ConnectionParameter class as follow:

int selectedConnectionType = connectionSelector.getSelectedItemPosition();
ConnectionParameter connectionParams = selectedConnectionType == ConnectionType.TYPE_USB
    ? ConnectionParameter.newUsbConnection(null)
    : ConnectionParameter.newUdpConnection(null);
