Looks like android front flash is not supported ! [FEATURE-REQUEST]

I checked the source code. and found

@Override
    public void initializeCameraManager(ConfigurationProvider configurationProvider, Context context) {
        super.initializeCameraManager(configurationProvider, context);

        this.manager = (CameraManager) context.getSystemService(Context.CAMERA_SERVICE);

        WindowManager windowManager = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
        Display display = windowManager.getDefaultDisplay();
        Point size = new Point();
        display.getSize(size);
        windowSize = new Size(size.x, size.y);

        try {
            String[] ids = manager.getCameraIdList();
            numberOfCameras = ids.length;
            for (String id : ids) {
                CameraCharacteristics characteristics = manager.getCameraCharacteristics(id);

                int orientation = characteristics.get(CameraCharacteristics.LENS_FACING);
                if (orientation == CameraCharacteristics.LENS_FACING_FRONT) {
                    faceFrontCameraId = id;
                    faceFrontCameraOrientation = characteristics.get(CameraCharacteristics.SENSOR_ORIENTATION);
                    frontCameraCharacteristics = characteristics;
                } else {
                    faceBackCameraId = id;
                    faceBackCameraOrientation = characteristics.get(CameraCharacteristics.SENSOR_ORIENTATION);
                    backCameraCharacteristics = characteristics;
                }
            }
        } catch (Exception e) {
            Log.e(TAG, "Error during camera init");
        }
    }

looks like it is checking the lens orientation/facing, but did not find usage of FLASH_INFO_AVAILABLE anywhere.

Are you looking for screen flash when in front camera mode?

[mwshubham]

no, there are some devices which support front flash as well. However, the current version of the library does not support it.
