i can getting the image width through

MediaStore.Images.Media
normally

but i need to getting the image width and height from image which selected from dropbox

so currently i have following method to getting image size from dropbox

private void getDropboxIMGSize(Uri uri){
String size = Long.toString(new File(uri.getPath()).length());
return size;
}


but what i actually need are getting the file width and height value

anyone know how to achieve that?please help!

Answer
private void getDropboxIMGSize(Uri uri){
   BitmapFactory.Options options = new BitmapFactory.Options();
   options.inJustDecodeBounds = true;
   BitmapFactory.decodeFile(new File(uri.getPath()).getAbsolutePath(), options);
   int imageHeight = options.outHeight;
   int imageWidth = options.outWidth;

}

no there is no way. You have to create a Bitmap object. if you use the inJustDecodeBounds flag the bitmap would not be loaded in momery. In fact BitmapFactory.decodeFile will return null. In my example uri is the phisical path to the image
