Estou trabalhando no aplicativo Lanterna com Widget. Quando ligo a lanterna com a lanterna Widget, a lanterna está ligada e, quando inicio algum aplicativo, a lanterna se apaga. Por que isso está acontecendo? Por que minha lanterna não pode ser executada em segundo plano? Como posso evitar isso? Quero que o Flashlight seja desligado apenas pelo usuário e não pelo sistema.

Este é o meu código para o widget:

    @Override
    public void onReceive(Context context, Intent intent) {
        RemoteViews views = new RemoteViews(context.getPackageName(),
                R.layout.widget_layout);
        myPref = PreferenceManager.getDefaultSharedPreferences(context);
        if (AppGlobals.getIsFlashOn()) {
            views.setImageViewResource(R.id.flashlight_widget_imageview,
                    R.drawable.light_on);
        } else {
            views.setImageViewResource(R.id.flashlight_widget_imageview,
                    R.drawable.light_off);
        }

        AppWidgetManager appWidgetManager = AppWidgetManager
                .getInstance(context);
        appWidgetManager.updateAppWidget(new ComponentName(context,
                FlashlightWidgetProvider.class), views);

        if (AppGlobals.getIsFlashOn()) {
            if (getmCameraWidget() != null) {
                flashOffWidget();

            }

            if (Flashlight.getmCameraActivity() != null) {

                flashOffApp();
                Flashlight.flashlight_button
                        .setBackgroundResource(R.drawable.light_on);

            }

            Flashlight.turnMotorolaOff();
            isLightOn = false;
            NotifyFlashlight(context, isLightOn);

        } else {
            try {
                setmCameraWidget(Camera.open());
            } catch (Exception e) {
                e.printStackTrace();
            }

            if (getmCameraWidget() == null) {
            } else {
                setParamsWidget(getmCameraWidget().getParameters());

                List<String> flashModes = getParamsWidget()
                        .getSupportedFlashModes();

                if (flashModes == null) {
                    return;
                } else {
                    if (count == 0) {
                        getParamsWidget().setFlashMode(
                                Parameters.FLASH_MODE_OFF);
                        getmCameraWidget().setParameters(getParamsWidget());
                        getmCameraWidget().startPreview();
                        AppGlobals.setIsFlashOn(true);
                    }

                    String flashMode = getParamsWidget().getFlashMode();

                    if (!Parameters.FLASH_MODE_TORCH.equals(flashMode)) {

                        if (flashModes.contains(Parameters.FLASH_MODE_TORCH)) {
                            getParamsWidget().setFlashMode(
                                    Parameters.FLASH_MODE_TORCH);
                            getmCameraWidget().setParameters(getParamsWidget());
                        } else {
                            getParamsWidget().setFlashMode(
