# Group6Project
# Group6DEMO
Instructions:
1) Go to Foswiki and click on link. This will lead you to ‘Group6demo’ project.
2) Clone master branch and open it in android studio
- Allow build.gradle to complete and configure the device to be Pixel 2A API 30 (Create Device > Pixel 2 > R)
Files to take note of:
- badImage.txt = sample of wrong input to test the Toast feature
- goodImage.txt = sample of correct input
- blur.jpg = sample image to test for blur
3) To include the previous mentioned files into the emulator:
Select “upload text”
4) Drag the desired image (in .txt format) onto the emulator
5) Go to “Download” and click on the file to display it on screen
