Question

I think that handlers in android are tools to get different objects that are in a Thread and move it to another Thread for example UI thread in android.
Is it true?
Sorry for my knowledge 🙂

Thanks!

From the documentation,

A Handler allows you to send and process Message and Runnable objects
associated with a thread’s MessageQueue. Each Handler instance is
associated with a single thread and that thread’s message queue. When
you create a new Handler, it is bound to the thread / message queue of
the thread that is creating it — from that point on, it will deliver
messages and runnables to that message queue and execute them as they
come out of the message queue.
