android button アイコン
Image asset studio places the newly generated icons in density specific folders under the res directory in your project. In accordance with material design icon guidelines for active icons we recommend using either black at 54 opacity or white at 100 opacity when displaying these on light or dark backgrounds respectively if an icon is disabled or inactive using black at 26 or white at 30 for light and dark backgrounds. Android studio includes a tool called image asset studio that helps you generate your own app icons from material icons custom images and text strings it generates a set of icons at the appropriate resolution for each pixel density that your app supports.
