The first thing users see of your app is its icon, so it's important to make a good first impression. Leaving this Project Property blank leaves you with a generic Android icon that indicates your Multi-App is not ready for anyone to see yet. Since you already have several PNGs you can quickly edit to a square, small shape with a quick crop and export, it doesn't take long to add the "cherry on top".
You need to share your App on your Portfolio as well as turn it in to Google Classroom as an AIA project as well as an APK. This video shows how to get your app to your PORTFOLIO FILES - DO NOT DELETE folder and turn it into a QR code for visitors to scan with Android devices.

Use a website such as The-QRcode-Generator to convert the link to your APK in Google Drive into a QR Code like the one here. You have to have already uploaded it to your DO NOT DELETE folder. This makes it very easy for users to point a device at your Android Programming portfolio page and to install your Multi-App. The QR Code by itself is not going to entice visitors to take the time to do this, so screenshots and a video of your app in action are essential!
It's much easier to install an app on a phone or regular tablet, but it CAN be done using a Kindle Fire and the AI Companion app; it just takes a little effort. Test your QR code at least once and make sure you have a PNG icon!
Do NOT add your APK file (or any file on your Portfolio) to ANY assignment from Google Drive! You must upload the file twice - once to Google Drive for the sharing QR Code and once to the assignment!
