将App Engine数据存储区中的Blob显示为图像

I have an App Engine Connected Android Project, so I am using endpoints. I ultimately converted the bitmap from my Android project into an encoded string to use in my setter, where I converted this string back into a byte array and then to a Blob, and then persisted the blob to the datastore. I know when to retrieve this Blob and display it as the actual image on the app engine front end. How can I do this? I'm a very beginner, especially with using Blobs.I have an App Engine Connected Android Project,
