Intent does not set the camera parameters

Question

I am opening camera app as external intent from my applications. I am using following code to invoke the camera and following are my conditions:

1. It should open the front camera.
2. Highest picture quality.
3. Flash light has to be on

Following is my code:

Intent action = new Intent("android.media.action.IMAGE_CAPTURE");   

        action.putExtra("android.intent.extras.CAMERA_FACING", 1);
        action.putExtra("android.intent.extras.FLASH_MODE_ON", 1);
        action.putExtra("android.intent.extras.QUALITY_HIGH", 1);

Now, it does open the front camera BUT it does not turn on the flash and it does not set the picture quality to high.

My Manifest file's permission section looks like following:

<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.FLASHLIGHT"/>
<uses-feature android:name="android.hardware.camera" />
<uses-feature android:name="android.hardware.camera.autofocus" />
<uses-feature android:name="android.hardware.camera.flash" />

is there anything that I am missing?

Unfortunately, when using the camera with Intent, the only extra parameter you can set is

MediaStore.EXTRA_OUTPUT

Eg

fileUri = getOutputMediaFileUri(MEDIA_TYPE_IMAGE); // create a file to save the image
intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri); // set the image file name

Which allows you to map where the Camera application will store the image.

Camera Facing intent extra can sometimes work:

action.putExtra("android.intent.extras.CAMERA_FACING", 1);

Looking in the android source files, there are some "test" methods that are in the Util class file but not officially documented:

(Util)

private static final String EXTRAS_CAMERA_FACING =
        "android.intent.extras.CAMERA_FACING";

// This is for test only. Allow the camera to launch the specific camera.
public static int getCameraFacingIntentExtras(Activity currentActivity) {
    int cameraId = -1;

    int intentCameraId =
            currentActivity.getIntent().getIntExtra(Util.EXTRAS_CAMERA_FACING, -1);

    if (isFrontCameraIntent(intentCameraId)) {
        // Check if the front camera exist
        int frontCameraId = CameraHolder.instance().getFrontCameraId();
        if (frontCameraId != -1) {
            cameraId = frontCameraId;
        }
    } else if (isBackCameraIntent(intentCameraId)) {
        // Check if the back camera exist
        int backCameraId = CameraHolder.instance().getBackCameraId();
        if (backCameraId != -1) {
            cameraId = backCameraId;
        }
    }
    return cameraId;
}

And in the photomodule, the following method is used:

(PhotoModule)

private int getPreferredCameraId(ComboPreferences preferences) {
    int intentCameraId = Util.getCameraFacingIntentExtras(mActivity);
    if (intentCameraId != -1) {
        // Testing purpose. Launch a specific camera through the intent
        // extras.
        return intentCameraId;
    } else {
        return CameraSettings.readPreferredCameraId(preferences);
    }
}

And when the camera app initialises the photo mode, it calls this method to check which camera to use:

mCameraId = getPreferredCameraId(mPreferences);
