Android Stuff at Disposal

Android Stuff at Disposal

Storage: You can package data files with your application for things that do not change, such as icons or help files. You also can carve out a small bit of space on the device itself, for databases or files containing user-entered or retrieved data needed by your application. And, if the user supplies bulk storage, like an SD card, you can read and write files on there as needed. 
Network: Android devices generally are Internet-ready, through one communications medium or another. You can take advantage of the Internet access at any level you wish, from raw Java sockets all the way up to a built-in WebKit-based web browser widget you can embed in your application.
Multimedia: Android devices have the ability to play back and record audio and video. While the specifics may vary from device to device, you can query the device to learn its capabilities and then take advantage of the multimedia capabilities as you see fit, whether that is to play back music, take pictures with the camera, or use the microphone for audio note-taking.
Location services: Android devices frequently have access to location providers, such as GPS and cell triangulation, which can tell your applications where the device is on the face of the Earth. In turn, you can display maps or otherwise take advantage of the location data, such as to track a device’s movements if the device has been stolen.
Phone services: Because Android devices are typically phones, your software can initiate calls, send and receive SMS messages, and do everything else you expect from a modern bit of telephony technology.
