This document provides a technical examination of Mono for Android version 1.2.0.24718. This release represents a critical milestone in the pre-Microsoft acquisition era of Xamarin. It provided a bridge for .NET developers to target the Android ecosystem using C# and the Common Language Runtime (CLR). This paper analyzes the binding architecture, the Just-In-Time (JIT) compilation specifics of the Mono runtime on Android, and the feature set introduced in this specific version.
This article provides a comprehensive exploration of this release: what it contained, why version 1.2.0.24718 mattered, how it worked under the hood, and where you might still encounter it today.
The single most important upgrade in version 1.2 was a major overhaul of its distributed Mono/Java garbage collector. The garbage collector, which manages memory automatically, received numerous bug fixes and significant performance enhancements. This improvement was critical because improper memory management could lead to application lag or crashes on Android devices with limited resources. Xamarin strongly urged all users to upgrade, as the stability gains were substantial. Mono for Android v1.2.0.24718.zip

Released in September 2011, Mono for Android v1.2.0.24718 was an early version of the Xamarin.Android framework, focusing on enhanced Visual Studio 2010 integration, API coverage, and performance optimizations for running .NET on Android. As a legacy release, this version is deprecated in favor of modern tools like .NET MAUI, with early versions notable for a larger app footprint.

: This shared object was the true heart of the runtime. It embedded the Mono VM inside any Android process, loaded .NET assemblies from the APK, and marshaled calls between C# and Java.
On Android, Mono utilized JIT compilation to execute managed code directly on the device.
