Please, help me for code

[zh25lt]

Hello, please don't scold me if I write off-topic. I have just started learning JAVA and I want to use this library for my studies. I'm trying to understand how it works in JAVA. I want to connect the arduino to the androcid, so that the android immediately reads data from the arduino (output in 1 line). Arduino sends data in the form of an array, I want to learn how to process an array on android (java). You don't need anything extra, just a working example of reading data when connecting an arduino. Please help me.
