- Sometimes students will manually adjust the dimensions of an image in App Inventor so that it fits a particular screen size; however, the image will not automatically adjust to a different sized screen.
- To fix this, remind students to select “Fill parent” so their image fills up any size screen.
- If students hard-code their apps to be the size of their phone screen, the app will show up phone-sized on larger screens (like tablets), leaving the rest of the screen outside of this small area useless and empty.
- Having both an Android device and a tablet in class is helpful so that students can see how their projects will look on differently sized screens.
- This gives the students an opportunity to uncover this misconception on their own.
