I am getting an image from gallery in onActivityResult() through intent.getdata().

Now i get the data and set it to a bitmap, its size is 716x716 and its setting to full screen. (ImageView's width and height is set to wrap content). Now i created another bitmap after scaling the original through Bitmap.CreateScaledBitmap(orgBitmap,30,30,false);

After this, i make sure these things(width,height n size) and they happen as they should be but the problem is that the image is still taking the full screen... rather it should only take 30dp x 30dp.

Anyone have an idea what might be the problem??? Thanx

Hi! How can I determine/calculate the byte size of a bitmap (after decoding with BitmapFactory)? I need to know how much memory space it occupies, because I'm doing memory caching/management in my app. (file size is not enough, since these are jpg/png files) Thanks for any solutions! >>> More
