Android Studio, Single Method Class Object

Requesting Java class object with a single public method, in the below style, that can be called from OnCreate in MainActivity. public Boolean takePhoto(String newPhotoName){ // 1. Take photo without user interaction, i.e. no need to press shutter button or confirm preview, so that application can run autonomously. // 2. Save photo as [login to view URL], so that I can dependably find it later. // 3. Save photo to same folder as default camera app, i.e. /storage/emulated/0/DCIM/Camera/[login to view URL], so that Google Photos will back it up separately. // 4. Return true if successful, false if not }
