Inspired by the classic analog etching toy, this app lets you use two knobs to sketch anything you can imagine.
This app was a good opportunity to implement some custom Android views for the knobs/dials, use the accelerometer to detect shaking, and use FileProvider to share content to other apps. The user’s etchings are rendered to the screen using Android’s Canvas and SurfaceView APIs.
- Change colors & line widths
- Precision erasing - or shake your phone to erase the whole thing (of course!)
- Save your etchings to your gallery
- Share your etchings to social media, messaging apps, etc.
