Xamarin.Android with support for Android 7.0 for both Xamarin Studio and Visual Studio is now available in the Beta channel, alongside with support for Xamarin.iOS 10.
Along with new features and capabilities, Android 7.0 includes a variety of system and API behavior changes. If you have previously published an app for Android, be aware that your app might be affected by these changes in the platform
At the top of the list of updates that may impact your application is the change to Android apps linking to platform libraries. This change disallows apps from dynamically linking against non-NDK libraries and may cause your app to crash. Even if your app is not specifically linking against a private library, you may be using a library that is, such as SQLite (which uses the platform libsqlite.so) or other libraries that are linking against libcutils.so, libcrypto.so, or libssl.so. It’s important to start testing now to see if your application needs to be updated in accordance with these changes.
