Best way to show a loading/progress indicator?

ProgressDialog is deprecated from Android Oreo. Use ProgressBar instead

ProgressDialog progress = new ProgressDialog(this);
progress.setTitle("Loading");
progress.setMessage("Wait while loading...");
progress.setCancelable(false); // disable dismiss by tapping outside of the dialog
progress.show();
// To dismiss the dialog
progress.dismiss();

OR

ProgressDialog.show(this, "Loading", "Wait while loading...");

By the way, Spinner has a different meaning in Android. (It's like the select dropdown in HTML)

If your application uses default navigation bar then you can't able to show progress bar beneath the status bar as navigation bar position is default at top of the view. You cant change that. But if you want to show progress bar with navigation bar then you need to customized the navigation bar.

And if your application doesn't have navigation bar then you can directly use progress bar on top of the view so that it will appear exact below to the status bar. Hope this will help you.
