When using it without options, it will return an image. But when I use it with options as in. What I'm trying to do is to downsample a Bitmap before I actually load it to save memory.
I've read some good guides, but none using. Handling large Bitmaps, bitmapfactory.decodestream returns null when downloading a png file. Image Processing in Android. The problem was that once you've used an InputStream from a HttpUrlConnection to fetch image metadata, you can't rewind and use the same InputStream bitmapfactory.decodestream returns null when downloading a png file. I think the problem is with the "calculate-scale-factor" logic because rest of the code looks correct to me assuming of course that inputstream is not null.
It would be better if you can factor out all the size calculation logic from this routine into a method call it calculateScaleFactor or whatever and test that method independently first. Learn more.

What's the output from your System. Is indicating that options. Yes, it returns an acceptable value every time. Removed the statement due to it being debug.
Thanks for posting your solution, but there's just one more thing to do. This question still appears in the "unsolved questions" lists because you haven't marked a response as "accepted".
You can do that by clicking the tickmark icon next to an answer. You could accept Samuh's answer if you feel it helped you find the solution, or you could post bitmapfactory.decodestream returns null when downloading a png file answer of your own and accept it. Normally you'd put your solution in your answer, but since you've already included that by editing your question, you could just refer them to the question.
Therefore you have to create a new InputStream for the actual sampling of the image. Does this mean the image has to download twice? Once to get the size and once to get the pixel data? I have to say Bitmap class of Android sucks. It so confusing and frustrating to use.

Samuh Samuh Thanks alot for the answer!
I tried setting a final int value like 'options. But it results in the same issues. Logcat reads 'SkImageDecoder::Factory returned null', for every image that i tried to decode. However BitmapFactory. This is strange. Can you try to resize some Bitmap bundled in your resource?
Like open a resource file and try to decode it. If you can do that maybe there is some problem with the remote stream which is causing the decode to fail. The first BitmapFactory. But the following BitmapFactory.
I am afraid this is beyond me I would be interested to know what could possibly go wrong here because I am using similar code and it works just fine for me.
I've solved it. The issue lies in the http-connection. When you've read from the input-stream provided by the HttpUrlConnection once, you can't read from it again, and have to reconnect to do the second decodeStream. You can convert the InputStream to a byte array, and use the decodeByteArray.
