When the Android Callable Wrapper (ACW) is created from Java, the ACW constructor invoked the corresponding C# constructor.

Android Callable Wrappers (ACW)Īndroid Callable Wrappers are a JNI bridge used to invoke the managed code when we need Android runtime. So to access these APIs in Xamarin.Android, a managed callable wrapper is required that acts as a JNI (Java Native Interface) bridge to invoke the Android code and provide the support for overriding virtual methods and implementing the Java Interface. They are exposed only through the Android Runtime Java APIs available in the Android.*namespaces or Java.*namespaces. The Android operating system facilities like Audio, Graphics, OpenGL, and telephony are not available directly for native apps.

These are presented by the Android runtime. Net APIs or by using the classes exposed in the Android namespaces, which provide a bridge to the Java APIs. Xamarin.Android apps can access the various-low level features of the Android operating system, either by calling the. Both the runtime environment run on top of the Linux kernel and expose various APIs to access the android system. Mono runtime is written in C language and runs side by side in the Android Runtime (ART) virtual machine. Xamarin.Android apps run in the Mono execution environment.

Apart from system apps, we can also install third-party emails, messages like outlook, chats, twitter, facebook, etc. The android operating system comes with a set of system apps for emails, phone calls, messages, calendars, internet browsing, contacts, and many more. These APIs are helpful to interact with the Native C/C++ libraries and build rich UI for various task management like Activity management, notification management, resource management, etc. Java API frameworkĪPI framework of JAVA is a set of rich, extensible APIs to access the entire feature-set of the Android OS using Java Language. Also, we can access these Native C/C++ libraries using the Android Native Development Kit (NDK) within the Java Code using the Java Native Interface (JNI).

Ahead -of- time (AOT) compilation, this improves the speed and reduces the footprint of memory.Ĭ/C++ libraries provide the wider range of functions including 2D and 3D graphics drawing, Secure Socket Layer (SSL) communication, SQLite database management, media management like audio and video playback, display subsystem, and graphic layer management and implementation of the C systems Library (libs).Īndroid apps can access these libraries through the Java-based Android core Library APIs.

Build toolchains, such as compile the sources of Java into DEX bytecode, that can run on the Android platform.ĪRT had two main features when we compared to Dalvik.

The data is optimized for minimal memory (consume 50% less memory) than java bytecode. The code of the app must be transformed from standard Java class files to the Dalvik executable (.dex) format to execute within the ART. ART has been written to run the multiple VMS (virtual machines) on low memory devices. Android RuntimeĮach Android app is based on Android version 5.0 or higher, runs in its process and with its instance of the Android Runtime (ART). So, when we make a call to access the hardware device using the Java API, Android system load the library module for the component of hardware. The Android HAL contains the multiple library modules for a specific type of hardware components, such as the camera and the Bluetooth module.

The hardware abstraction layer (HAL) helps the Android/Application framework to communicate with the hardware-specific device drivers with the higher-level of java API.

The Android Runtime (ART) depends on the Linux Kernel for all the functionalities such as low-level memory management and threading. Linux kernel provides the multitasking execution environment, which allows the multiple processes to execute concurrently.

The android operating system is a Linux-based stack of software components which can be divided into five sections, as shown in the below diagram. The native Android apps can be developed using Android Studio or Eclipse using Java as a programming language. Android provides the rich application framework that allows us to build innovative apps and games for mobile devices in the Java Environment. Android was initially developed by Android incorporation and purchased by Google. Android developmentĪndroid is an open-source operating system which is based on Linux Kernel.

Before proceeding further, we will focus on Android architecture and development tools with Java. Xamarin.Android provides the same UI controls as we have in Android with Java. Xamarin.Android is a part of the Xamarin family to build the native android app using C# and Xamarin.
