ByteArrayOutputStream baos = new ByteArrayOutputStream();
    FileOutputStream fo = null;

    bMap.compress(Bitmap.CompressFormat.JPEG, 40, baos);        


    File dst = new File (photoName + ".jpg");
    try 
    {
    dst.createNewFile();
    //write the bytes in file       
    fo = new FileOutputStream(dst);
    fo.write(baos.toByteArray());
    }
    catch (IOException e)
    {
        Log.e("Photo Convert","Error creating file. Check: "+dst, e);
    }

After that, you'll be able to check file dst size and other stuff. Hope it'll help
