Compatibility issues with releases of Android and App Inventor
The Android operating system and App Inventor are both evolving systems with frequent updates. When we update MIT App Inventor, we try to maintain compatibility across Android versions, but this is not always possible. Here are some notes on issues dealing with changes in App Inventor releases:
- App Inventor apps created before 2013 will not work on devices running Android system 4.1 or newer systems.
- As of August 2015, MIT App Inventor will no longer work on devices running Android OS version 1.5 (cupcake, API level 3) or earlier. The minimum supported version is 1.6 (donut, API level 4)
