How to create serial queue in Android?

In iOS I can create GCD serial queue like this: 

let serialQueue = DispatchQueue(label: "serialQueue")

Blocks are executed in a FIFO order, one block at a time. How can I do it in Android?

This is how chunk of code can be performed on the queue:

serialQueue.async {

As I see AsyncTask is serial: "Starting with HONEYCOMB, tasks are executed on a single thread to avoid common application errors caused by parallel execution."

I guess t is FIFO, the execution.

Found this JAVA 8 concurrency tutorial.

There are number of options based on what your exact requirement is. If I'm getting your question correctly, an executor is what you need. And extend it to create a SerialExecutor like below,

https://developer.android.com/reference/java/util/concurrent/Executor.html

What are these blocks ? functions ? You need to make runnable objects for the executor to execute each of your blocks

Use Executor.newSingleThreadExecutor(). You can pass a Runnable or Callable<V> that represents the work to be done.
