Can I restart Previous Activity with current Activity?

Question

I know the way to restart current Activity, we do is

Intent intent=getIntent();
finish();
startActivity(intent);

but in my case, my settings is in the Settings Activity, if i change the settings and then go back to MainActivity the settings are not applied, I have to restart my app. So, In this case the best way is to restart Activity? Am I right? or there's another way? Suggest me the best way. Thanks!!

Intent intent=new Intent(currentActivity.this,AnotherActivity.class); startActivity(intent) — Queendevelopers, Aug 22 '16 at 12:41
The "standard" Android way would be to read the settings in the `onStart()` callback of your `MainActivity` and make the changes there. — kenny_k, Aug 22 '16 at 12:41
@theFunkyEngineer yes, Absolutely, I will call on onStart() but for example if the user change language from settings then comes backs to previous activity does the onStart() calls and change settings for them? — Queendevelopers, Aug 22 '16 at 12:47

Read your settings in the onStart callback of the Activity, and show the appropriate UI.

To update the Toolbar, call invalidateOptionsMenu() or supportInvalidateOptionsMenu() if you're using the support lib. This will trigger a call to onCreateOptionsMenu() where you can figure out what to show for the user's current settings.
