saving an image file to a specific directory

I am building an android app that accesses the camera but i am wanting to save the image into a specific folder but i have no idea how to go about it. do i use a URI builder?

this is the code i have to get the image from the camera.

Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
    File photo = new File(Environment
                    .DIRECTORY_PICTURES), "pic.jpg");
    intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(photo));
    imageUri = Uri.fromFile(photo);
    startActivityForResult(intent, TAKE_PICTURE);

You can create a file from your own directory like this:

private File openFileFromMyDirectory() {

    File imageDirectory = null;
    String storageState = Environment.getExternalStorageState();
    if (storageState.equals(Environment.MEDIA_MOUNTED)) {
        imageDirectory = new File(
                Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES), "com.myapp.camera");
        if (!imageDirectory.exists() && !imageDirectory.mkdirs()) {
            imageDirectory = null;
        } else {
            SimpleDateFormat dateFormat = new SimpleDateFormat("yyyyMMdd_HHmmss", Locale.getDefault());

            return new File(imageDirectory.getPath() +
                    File.separator + "IMG_" +
                    dateFormat.format(new Date()) + ".jpg");
        }
    }
    return null;
}

Then get bitmap from uri:

Bitmap mCameraBitmap= MediaStore.Images.Media.getBitmap(this.getContentResolver(), imageUri);

Finally save the bitmap into the file

private void saveImageToFile(File file) {

    if (mCameraBitmap != null) {
        FileOutputStream outStream = null;
        try {
            outStream = new FileOutputStream(file);
            if (!mCameraBitmap.compress(Bitmap.CompressFormat.JPEG, 100, outStream)) {
                Toast.makeText(this, "Unable to save image to file.",
                        Toast.LENGTH_LONG).show();
            } else {
                Toast.makeText(this, "Saved image to: " + file.getPath(),
                        Toast.LENGTH_LONG).show();
            }
            outStream.close();
        } catch (Exception e) {
            Toast.makeText(this, "Unable to save image to file.",
                    Toast.LENGTH_LONG).show();
        }
    }
}
