Android is an open source operating system developed by Google and the Open Handset Alliance for use in mobile devices. It uses a modified Linux kernel and other open source software, allowing developers to write managed code using Java-like languages. Applications are compiled into Dalvik bytecode to run on Android's optimized virtual machine. The Android platform is designed to break down barriers between applications by allowing them to share components and data through its intent system.
