Programmatically enabling/disabling accessibility settings on Android device

How can I programmatically enable/disable an android screen reader service such as TalkBack?

I am developing a kiosk type application that will be installed on an Androi

Only system apps can enable/disable accessibility service programatically. System apps can directly write in settings secure db to start accessibility service.

Settings.Secure.putString(getContentResolver(),Settings.Secure.ENABLED_ACCESSIBILITY_SERVICES, "com.packagename/com.packagename.componentname");

Following permission is required to write in settings secure db:

For non system apps, only way to start accessibility service is direct them to accessibility settings screen via intent and let user manually start the service :

Intent intent = new Intent(Settings.ACTION_ACCESSIBILITY_SETTINGS);
