To get the height and width, you call:

Uri imagePath = Uri.fromFile(tempFile);//Uri from camera intent
//Bitmap representation of camera result
Bitmap realImage = BitmapFactory.decodeFile(tempFile.getAbsolutePath());
realImage.getHeight();
realImage.getWidth();

To resize the image, I just supply the resulting Bitmap into this method:

public static Bitmap scaleDown(Bitmap realImage, float maxImageSize,
            boolean filter) {
    float ratio = Math.min((float) maxImageSize / realImage.getWidth(),
            (float) maxImageSize / realImage.getHeight());
    int width = Math.round((float) ratio * realImage.getWidth());
    int height = Math.round((float) ratio * realImage.getHeight());

    Bitmap newBitmap = Bitmap.createScaledBitmap(realImage, width, height,
            filter);
    return newBitmap;
}

The basic actually is just Bitmap.createScaledBitmap(). However, I wrap it to another method to scale it down proportionally.
