This question is quite similar to this SO question.
What I am currently using is the below code to take the user to setting page.
Intent dummyIntent = new Intent(android.provider.Settings.ACTION_ACCESSIBILITY_SETTINGS);
startActivity(dummyIntent, 0);
But this takes the user only to the settings page. Shown below in the pic.
Instead of this, I would like to take the user to the settings page of my app, where he has the option to turn it on and shows my app description.
