Answer 1

Because accessibility services are able to explore and interact with on-screen content, a user has to explicitly enable services in Settings > Accessibility. Once a service is enabled, the system will start it automatically and bind it to the accessibility APIs.

Make sure you declare your service in your application manifest:

     
         
     
     . . .
 

You'll also need to provide configuration for your service, either by overriding setServiceInfo(AccessibilityServiceInfo) or adding a meta-data attribute and XML config file.

The meta-data attribute goes in your declaration after the tag and looks like this:

The XML config that you're referencing (in this case, accessibilityservice.xml) looks like this:
