Answer 1

You need to add all your notification icon in below all directories

res/drawable-mdpi/ (24x24)

res/drawable-hdpi/ (36x36)

res/drawable-xhdpi/ (48x48)

res/drawable-xxhdpi/ (72x72)

res/drawable-xxxhdpi/ (96x96)

res/drawable-xxxhdpi/ (256x256)

• If you miss an icon size, it may not display correctly.
• If you see a solid square, you set the image correctly, but did not generate with transparency in the shape you want to show.
• If you see a white square in the preview on the page above you did not set the alpha channel correctly on your icon.
• you must be sure the icon filenames are correct.
