I used the MIT App Inventor site to create an Android app that…
- Uses the camera to take a picture and saves it to the device’s gallery
- Let’s you select a picture from the gallery
- The image is converted into base64 and uploaded to a web app
- Additionally, it also sends rotation and lat/lng coordinates and lets you add a textual comment as well.
This Android app sends it to an Apps Script web application inside a Google Spreadsheet
Nice fun project from Tom Smith that use MIT App Inventor to create an Android app that is able to send data to a Google Sheet. Check out the source link for all the code you need.
