The minimum Android SDK version required for developing apps for Android 11 is 30. This means that any app that targets Android 11 or higher must have a minimum SDK version of 30 specified in its manifest file. Developers should ensure that their apps use the latest API features to deliver the best possible user experience while also maintaining compatibility with earlier versions of Android. It's important to note that apps targeting lower SDK versions may still run on Android 11, but they may not be able to take advantage of the latest features and improvements introduced in the new platform release.
