Android: How shall I create Bitmap image bast on byte array?

Question

I have a byte array that I want to save it as a bitmap image. what should I do? I saw android.graphics.Bitmap and found several methods but I don't know which one is suitable. createBitmap(int width, int height, Bitmap.Config config), for example. I have width and height but how can I give it my byte array?

Thanks

Check out the methods in the class BitmapFactory, e.g. public static Bitmap decodeByteArray(byte[] data, int offset, int length).

Offset should be 0 and the length should be array.length for you.

Thanks dear mreichelt. may be a stupid question, sorry, but i ask. How it understand the width and height of my picture. actually, I had a picture then I extracted pixels and then manipulated pixels and know I want to save it with new name. this is my real problem.
