byte array must be in range 0 < M <= 32

You can simply convert a string to a bytes32 format in kotlin or solidity

Solidity:

    function stringToBytes32(string memory source) private pure returns (bytes32 result) {
        bytes memory tempEmptyStringTest = bytes(source);
        if (tempEmptyStringTest.length == 0) {
            return 0x0;

Chapter 1: Que es RxJava?

RxJava is a Java VM implementation of Reactive Extensions
Reactive Extensions: a library for composing asynchronous and event-based programes by using observables

Observable: Emits the value
Observer: Retrieves the value by subscribing to observable

Flowable, Observable, Single, Completable, Maybe: Does work and emit value
Subscription:  Work is going on or completed or is used to cancel
