BitmapDrawable(bitmap) is deprecated. – Nombril

ImageButton#setBackgroundDrawable(Drawable) is deprecated as well. The answer by Sruit A.Suk is better. – Adrianadriana

Answer 2

you need to check current version of Android also

Button bProfile; // your Button
Bitmap bitmap; // your bitmap

if(android.os.Build.VERSION.SDK_INT < 16) {
    bProfile.setBackgroundDrawable(new BitmapDrawable(getResources(), bitmap));
}
else {
    bProfile.setBackground(new BitmapDrawable(getResources(),bitmap));
}

Hey First learn about Handling bitmaps: http://developer.android.com/training/displaying-bitmaps/process-bitmap.html

You should not process bitmaps on the UI thread at all. Once you have attained Bitmap use ImageView's method setImageBitmap(Bitmap bitmap).

To fetch images through network, You can also use libraries like picasso, Universal Image Loader, Volley to attain what you are wanting.
