Starting a service via a SwitchPreference

Question

can anyone tell me how can I start/stop a location service (or any other service) when a SwitchPreference in a PreferenceScreen is toggled on/of? I'm using a settingsFragemnt (extending PreferenceFragemntCompat), which is hosted in my settings activity.

Could you please add your fragment code? – Volodymyr Bereziuk Feb 12 '20 at 12:04 — Volodymyr Bereziuk, Feb 12 '20 at 12:04

You should add OnPreferenceChangeListener which will allow you to listen switch changes:

   final SwitchPreference onOffRandomColor = (SwitchPreference) findPreference(this.getResources()
                                                    .getString(R.string.sp_key_on_off_random_color));

        onOffRandomColor.setOnPreferenceChangeListener(new Preference.OnPreferenceChangeListener() {
            @Override
            public boolean onPreferenceChange(Preference preference, Object o) {
                if(onOffRandomColor.isChecked()){

                }else {

                }
                return false;
            }
        });

Next step is to run service:

startService(new Intent(this, LocationService.class));

yeah I know, my point is how can I start the service inside the listener? because what i did seems not to work – Mohammad Feb 12 '20 at 12:16
Is Location service your custom service ? You can start custom service via startService(new Intent(this, LocationService.class)); In your case @Override public boolean onPreferenceChange(Preference preference, Object newValue) { Settings.setBoolean(Settings.DO_NOT_LOCATE, true); startService(new Intent(this, LocationService.class)); return false; } – Volodymyr Bereziuk Feb 12 '20 at 12:19

my fragment looks like this:

public class SettingsFragment extends PreferenceFragmentCompat {

@Override
public void onCreatePreferences(@Nullable Bundle savedInstanceState, String rootKey){
    setPreferencesFromResource(R.xml.prefs, rootKey);

    // setting summaries for both list preferences ---------------------------------------------
    ListPreference photo_quality = findPreference("photo_quality");
    if (photo_quality != null){
        photo_quality.setSummaryProvider(ListPreference.SimpleSummaryProvider.getInstance());
    }

    ListPreference uploads = findPreference("upload_options");
    if (uploads != null) {
        uploads.setSummaryProvider(ListPreference.SimpleSummaryProvider.getInstance());
    }

    // setting the visibility for location service ---------------------------------------------
    if (!Auth.getCanDeactiveGps()){
        Objects.requireNonNull(getPreferenceScreen()
                .findPreference("location_category")).setVisible(false);
    }

    // handling locationSwitchPreference change ------------------------------------------------
    SwitchPreference locationSwitch = findPreference("location");

    if (locationSwitch != null){
        locationSwitch.setChecked(Settings.getBoolean(Settings.DO_NOT_LOCATE,
                false));

        locationSwitch.setOnPreferenceChangeListener(
                new Preference.OnPreferenceChangeListener() {

            @Override
            public boolean onPreferenceChange(Preference preference, Object newValue) {
                Settings.setBoolean(Settings.DO_NOT_LOCATE, true);
                return false;
            }
        });
    }
}
