How to get the size of an image in Android?

Question

I'm able to get the height and width of an image. But is there a method to retrieve the size (in bytes or kb or mb) for an image stored in the phone?

File file=new File(Environment.getExternalStorageDirectory(), "image.file"); long length = file.length(); — Eric Goncalves, Feb 16 '12 at 18:37
Before this, how you were getting the height and width of the image? — Akshatha S R, Aug 01 '14 at 09:38

Thank you for your answers. This is how I finally resolved it:

 Bitmap bitmapOrg = BitmapFactory.decodeResource(getResources(), 
            R.drawable.ic_launcher);


     Bitmap bitmap = bitmapOrg;
     ByteArrayOutputStream stream = new ByteArrayOutputStream();   
     bitmap.compress(Bitmap.CompressFormat.JPEG, 100, stream);   
     byte[] imageInByte = stream.toByteArray(); 
     long lengthbmp = imageInByte.length;

Appreciate your time and answers :)

Goon Answer. lengthbmp is in byte. lengthbmp/1024.0 is in KB. lengthbmp/1024.0/1024.0 is in MB. – mazend Feb 05 '20 at 15:23
How to get before compress and after compress? – Pratik Butani Sep 19 '20 at 10:57
Before compressing you can use `bitmap.getByteCount()`. Bear in mind that the "compressed" version is a JPEG, so if you compare both sizes you're not necessarily comparing apples to apples. – Douglas Kazumi Sep 02 '21 at 23:56

You just need to create a new File object such as...

String filepath = Environment.getExternalStorageDirectory() + "/file.png";
File file = new File(filepath);
long length = file.length();

this gives the size of the file, not the image. – Avinash R Aug 27 '15 at 12:04

Assuming your talking about a bitmap (and NOT an ImageView), there is a method Bitmap.getByteCount().

@mehmet Yes, but as of two years ago, when this was posted, it worked. I'll update when I get a chance. – Mike D May 03 '14 at 21:54

use [android.support.v4.graphics.BitmapCompat#getAllocationByteCount](https://developer.android.com/reference/android/support/v4/graphics/BitmapCompat.html#getAllocationByteCount%28android.graphics.Bitmap%29) for compatibility. – Avinash R Aug 27 '15 at 12:01

 File file = new File("/sdcard/imageName.jpeg");
 long length = file.length();
 length = length/1024;
 System.out.println("File Path : " + file.getPath() + ", File size : " + length +" KB");

This returns the true size that is match in computers when you see file details with right click.

File file = new File("/sdcard/my_video.mp4");
long length = file.length() / 1024; // Size in KB
