Hey,

Below is my code to start/stop Flic feature on my application.
How do I remove flic buttons from Flic manager?

Here is my code:

findPreference(INTEGRATE_FLIC).setOnPreferenceChangeListener(new Preference.OnPreferenceChangeListener() {
             @Override
             public boolean onPreferenceChange(Preference preference, Object newValue) {
                 if (newValue.toString().equals("true")) {
                     PreferenceManager.getDefaultSharedPreferences(getContext()).edit()
                             .putBoolean(INTEGRATE_FLIC, false).apply();
                     FlicManager.setAppCredentials(FLIC_APP_ID, FLIC_APP_SECRET, FLIC_APP_NAME);
                     if (!isAppInstalled(getContext(), FLIC_PACKAGE_NAME)) {
                         flicNotInstalled();
                     } else {
                         FlicManager.getInstance(getContext(), new FlicManagerInitializedCallback() {
                             @Override
                             public void onInitialized(FlicManager manager) {
                                 manager.initiateGrabButton(getActivity());
                             }
                         });
                     }
                     } else {

                     //TODO: Invalidate button here!
                     //FlicManager.destroyInstance();
                     PreferenceManager.getDefaultSharedPreferences(getContext()).edit()
                             .putBoolean(INTEGRATE_FLIC, false).apply();
                 }
                 return true;
             }
         });

If I use FlicManager.destroyInstance(),
I'am getting the following exception:

How do I workaround this?

Hey,
I'm an android developer working with Flic integration for my application.
I am using Flic android SDK in my app to listen to Flics, I had these doubts:

Is there a way, I don't have to see FlicManager.getInstance() (The screenshot is attached)
every time I exit my app and start it?
Like is it necessary to configure the Flic manager every time to listen to flic buttons on start of the application, is there any workaround for this?

Also is there a way I can use Flic SDK without the Flic app installed?

Regards,
