Equivalent of dispatch_async in android

Hi All,

As a new android developer. I would like to know if there's an equivalent to iOS dispatch_async in android.
I would like to implement a background task/process to read a [bin] file and send it using BLE which is pretty much done in obj-C.
If there's no equivalent to dispatch_async in android what would be the best/simplest way to imitate this functionality?
I'm using Android Studio.

Thanks in advance.

What I have tried:

how it's been done in obj-C:

dispatch_async(dispatch_get_global_queue(0, 0), ^{
        //load your data here.
        dispatch_async(dispatch_get_main_queue(), ^{
            [_progressPercent setText:@"Preparing ..."];
        });
    });
