How to do this for Android using the drones of the Phantom series

Dear Client Thank you for contacting DJI. The isConnected() method is provided in both BaseComponent and BaseProduct to detect a connection. The SDKManagerCallback interface class provides several interfaces for detecting status. For example, the onProductChange() method will be called when the connected product is changed. The product will be updated when the aircraft connected changes from only remote controller connected. Hopefully our solution can help you. Kindly Regards, DJI Developer Support -
I'm sorry, I didn't make myself clear. I'd like something more reactive, like using the Observer pattern. I've just seen that you have the KeyListeners, and I noticed the ProductKey.CONNECTION but I couldn't find a RemoteControllerKey.CONNECTION.
Also, what is the difference between onProductConnect and onProductChanged?
In onProductConnect, the documentation says the base product can be null "if the USB link or WiFi link between the product and phone is disconnected", but if the product is connected, the USB or WiFi link wouldn't be also connected? What am I missing?
The documentation of onProductDisconnect says "Called when the 'product' is disconnected.". What this product in quotes mean?
