A Java ME implementation Android applications are written using the Java language, but they are not run within a Java ME (Mobile Edition) VM, and Java-compiled classes and executables will not run natively in Android. Part of the Linux Phone Standards Forum (LiPS) or the Open Mobile Alliance (OMA) Android runs on an open-source Linux kernel, but, while their goals are similar, Androids complete software stack approach goes further than the focus of these standards-defining organizations. Simply an application layer (such as UIQ or S60) Although Android does include an application layer, Android also describes the entire software stack, encompassing the underlying operating system, the API libraries, and the applications themselves. A mobile phone handset Android includes a reference design for mobile handset manufacturers, but there is no single Android phone. Instead, Android has been designed to support many alternative hardware devices. Googles answer to the iPhone The iPhone is a fully proprietary hardware and software platform released by a single company (Apple), whereas Android is an open-source software stack produced and supported by the Open Handset Alliance (OHA) and designed to operate on any compatible device.
Im kind of guessing you are new to Android. Honestly though, if you are interested in development this forum probably isn't the place. It is focused more on end users and getting the most out of specific devices.
You can say, I am new for this! I am in android development since last 6 months and wanted to be an expert of it.
Android has expanded beyond a pure mobile phone platform to provide a development platform for an increasingly wide range of hardware, including tablets and televisions. Put simply, Android is an ecosystem made up of a combination of three components: A free, open-source operating system for embedded devices An open-source development platform for creating applications Devices, particularly mobile phones, that run the Android operating system and the applications created for it Android is made up of several necessary and dependent parts, including the following: A Compatibility Definition Document (CDD) and Compatibility Test Suite (CTS) that describe the capabilities required for a device to support the software stack. A Linux operating system kernel that provides a low-level interface with the hardware, memory management, and process control, all optimized for mobile and embedded devices. Open-source libraries for application development, including SQLite, WebKit, OpenGL, and a media manager. A run time used to execute and host Android applications, including the Dalvik Virtual Machine (VM) and the core libraries that provide Android-specific functionality. The run time is designed to be small and efficient for use on mobile devices. An application framework that agnostically exposes system services to the application layer, including the window manager and location manager, databases, telephony, and sensors. A user interface framework used to host and launch applications. A set of core pre-installed applications. Native Android Applications x 5 A software development kit (SDK) used to create applications, including the related tools, plug-ins, and documentation.
here are some more Task Killers: As much as this is obvious, people still uses it. So much, that it is annoying. Android handles apps and tasks well. However, there is an exception, and that is when the app constantly freezes or crashes and you need to restart it. If that's the case, there's a "Running Apps" section, where you can force close apps under system settings. So you won't need 3rd party Task Killers, EVER Battery Calibration (Draining then fully charging): People thinks that this is good for your battery life, but it isn't. The only thing that this does is make the system read the battery percentage more accurate. Doing this once per month might help you improve read battery % better, but it isn't necessarily at all.
