The Core Of Android Architecture - 995 Words

It is the core of Android architecture that forms the foundation of Android. Linux kernel includes hardware drivers, power management, memory management, process management and binder driver, which provides all the fundamental services needed by the system. Although it is called Linux kernel, it is not a standard Linux kernel; Google has customized it for Android devices. The main difference between them is the binder driver, which is an Android-specific inter-process communication mechanism that enables one Android process to call a procedure in another Android process. Another major difference is the ashmem module, which is an Android version of shared memory allocator, similar to Portable Operating System Interface (POSIX) shm but with a simpler file-based API. And also the Power Manager has been enhanced to save battery, which is critical for smartphones. Libraries On top of Linux kernel are Libraries, which provide services written in native language like C and C++. It contains a long list of middle wares that include SQLite, WebKit, SSL, Media, C runtime library. SQLite is responsible for database, WebKit is for browser support, SSL is used to secure network transmissions. Android Runtime This layer contains core libraries and Dalvik Virtual Machine (DVM), which are needed to run Android applications. DVM is the Android implementation of Java Virtual Machine (JVM), which optimized for mobile apps for less memory consumption and better performance.
