Cannot resolve getIntent() method in Accessibility Service class

Make sure you add below code, where you want to start

Intent intent = new Intent(getApplicationContext(), AccessibilityService.class);
    intent.putExtra("data","value");
    startService(intent);

In your AccessibilityService class, make sure you override onStartCommand() method

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    super.onStartCommand(intent, flags, startId);
    String data="";
    if(intent.getExtras().containsKey("data"))
        data = intent.getStringExtra("data");
    return START_STICKY;
}
