Use .png or .svg + use src="your image" + delete this "android:background="@null" " from your code — POMAIIIUK, Aug 24 '19 at 18:57

Use paint.net to edit images.

Save the image and the white background is removed.

Are you certain the background is truly transparent in the image? If it isn't you can try to edit it first by adding it to Photoshop and moving the black pixels to a new layer with a transparent background. Or you can try any of the .svg converter websites which can render simple images as .svg which you can download as a .png.

If that doesn't work there seems to be a similar question answered here: https://stackoverflow.com/a/6873336/9530685
