Answer 1

Here is the general solution

ApplicationManager.getApplication().executeOnPooledThread(new Runnable() {
    public void run() {
        ApplicationManager.getApplication().runReadAction(new Runnable() {
            public void run() {
            // do whatever you need to do
            }
        });
    }
});

Answer 2

I have found a better way to run the process as background task where you can update the progress bar percentage and text

ProgressManager.getInstance().run(new Task.Backgroundable(project, "Title"){
        public void run(@NotNull ProgressIndicator progressIndicator) {

            // start your process

            // Set the progress bar percentage and text
            progressIndicator.setFraction(0.10);
            progressIndicator.setText("90% to finish");


            // 50% done
            progressIndicator.setFraction(0.50);
            progressIndicator.setText("50% to finish");


            // Finished
            progressIndicator.setFraction(1.0);
            progressIndicator.setText("finished");

        }});

If you need to read some data from another thread you should use

AccessToken token = null;
try {
   token = ApplicationManager.getApplication().acquireReadActionLock();
                    //do what you need
} finally {
   token.finish();
}
