How can code be structured without using the combine operator?

In Android, if you are structuring code without using the combine operator (for example, in RxJava or other reactive libraries), you can apply the following approaches:

• Sequential execution of operations: split the chain into separate methods and call them one after another.
• Using callbacks or listeners: instead of merging data streams with combine, process results separately and synchronize logic manually.
• Using coroutines (Kotlin): coroutines allow writing asynchronous code sequentially without needing to combine streams.
• Modular separation: divide logic into independent components that interact through interfaces or events.

For example, instead of combineLatest in RxJava, you can subscribe to each stream separately and update the state in handlers, checking the readiness of all data.

This approach may be less convenient but helps better control the flow and simplifies debugging.
