Question

When you get a bitmap from a resource for example with:

Bitmap src = BitmapFactory.decodeResource(getResources(), R.drawable.yourimage);

It is automatically scaled depending on the device’s screen density. How can I avoid that and retrieve it in its original pixel size whatever the screen density is?

Thanks

What do you mean “It is automatically scaled”? When you call this method Android takes image from folder res/drawable-?dpi – depending on device where app is running. If your ldpi folder contains 30*30px image, mdpi contains 40*40px image and hdpi contains 60*60px, you will get bitmap one of this sizes(depends on device). Android does not change anything.

If you see that on the screen your image scaled somehow, check properties of ImageView.
