Hello everyone,
I have few questions to ask.
1. what things (languages, protocols ) we need to learn to create a library like libnodave, moka7 etc?
2. What are the sources through which I can get the deep understanding of communication between plc and android?

Any sort of advice or help is appreciated
Thank you !!

There are a number of companies that already have remote access and HMI apps for this purpose. Ask you vendor, they may already have something.

First thing you need is experience in computer programming, and then a good level with Java language(or Kotlin) and also with XML
And then experience with Android programming.
And then with sockets programming, and next with multithreading, communicating protocols etc. All of this prior to select if you use a specific library

Communication protocols there are many, I recommend you start with a simple one, for example Modbus/TCP, it is simple enough to implement it yourself without third-party libraries, just reading the protocol specification.

My own HMI Android App uses my own code for all the supported protocols, then I don't know much about third part libraries, I only can say that Moka7 works on Android but only gives partial access to Siemens Step 7 PLCs.

Many other free libraries available on the internet are not compatible with Android.
