Android features

Android devices have several hardware features in them. This is what developers can use in building applications.
Among others are:
1. Touchscreen. Android devices have a touchscreen feature that gives users the possibility to interact with applications using their fingers. Users can swipe, flip, drag, and pinch to zoom. Android also supports multitouch which means the entire screen can be touched with one or more fingers at the same time
2. GPS. The Android operating system supports GPS which allows developers to access user locations. Examples of applications that utilize GPS are map applications that show the user's location and provide instructions for getting to a location.
3. Accelerometer. Android supports the Accelerometer, which is a device used to measure acceleration. An accelerometer can tell when an Android device is moving, shaking, or reversing its position.
4. SD Card. Android has a feature that allows users or other applications to access (save or open) files on the SD Card. SD Card is a storage medium that is used by Android devices and several other mobile devices.
Android has many software features that can be used by developers in developing applications, namely:
1. Internet. The ability to access the internet on Android provides many advantages. Various information in real-time can be obtained easily with the internet. Users can access the internet to see movie show schedules, weather of an area, flight schedules and more. Developers can use the internet to access / update data in realtime. Developers can also use the internet to store various assets for later use in an application, such as by Pandora and Youtube. With the internet, an application model called client-server computing can be built. Another example, a map application accesses map and GPS data from a web server.
2. Audio and Video Support. The Android operating system allows developers to easily include audio and video in the application. Various standard audio and video formats are supported.
3. Contact. Android allows access to contacts stored on the device. For example, developers can build applications that combine contacts with GPS to provide notifications if a user is near the address of one particular contact.
4. Security. Android allows applications to do many things. Android also prepares security mechanisms in the form of permissions relating to several tasks. Example: To download an image and save it on the SD Card, you must first approve the permission to access the SD Card.
5. Google APIs. The Android operating system makes it possible to unlimitedly make phone calls, organize contacts or install applications. Developers can also integrate maps into an application by using the Maps API which contains Map Widgets. Various features can be added with the Maps API, including: (1) Displaying a location on the map, (2) getting a navigation guide, (3) data communication between applications and clouds.
