Why is this so cool

Android is a full open-source platform for mobile devices. It has a full access to hardware level and free to develop software.



Features

* Application framework enabling reuse and replacement of components
* Dalvik virtual machine optimized for mobile devices
* Integrated browser based on the open source WebKit engine
* Optimized graphics powered by a custom 2D graphics library; 3D graphics based on the OpenGL ES 1.0 specification (hardware acceleration optional)
* SQLite for structured data storage
* Media support for common audio, video, and still image formats (MPEG4, H.264, MP3, AAC, AMR, JPG, PNG, GIF)
* GSM Telephony (hardware dependent)
* Bluetooth, EDGE, 3G, and WiFi (hardware dependent)
* Camera, GPS, compass, and accelerometer (hardware dependent)
* Rich development environment including a device emulator, tools for debugging, memory and performance profiling, and a plugin for the Eclipse IDE

-- Are you a Android Developer? --

If you going to develop an application using Android (specially hardware dependent application, just like new protocol for WI-FI or new network application), curren- tly you must have a mobile phone which is fully support Android OS. There was a Nokia phone and one Motorola phone which is support to Android partially. Because some Android features doesn't work will on those phones. That implies only T-Mobile G1 is the solution to such development. Android announce that they are going to issue a phone, for Android developments and they are call it as a Android Dev Phone 1 . Android Dev Phone 1 is a SIM-unlocked and hardware-unlocked device that is designed for advanced developers. The device ships with a system image that is fully compatible with Android 1.0, so you can rely on it when developing your applications. We can use any SIM in the device and can flash custom Android builds that will work with the unlocked bootloader. The device currently costs $399 (USD) (including free sh...

What is serialVersionUID?

If a class implements Serializable interface, your IDE worn you to add serialVersionUID or it add automatically. This variable holds a private static final long and IDE automatically declared it to 1L. class SerializeMe implements Serializable { private static final long serialVersionUID = 1L; private String data; public SerializeMe (String data) { this.data = data; } public String getData() { return data; } } Field data represents some information stored in the class. Note that serialVersionUID is a static value, then it should not have been serialized. But why is this so impotent? public class SerialVersionUIDTester { public static void main(String [] args) throws Exception { File file = new File("out.ser"); FileOutputStream fos = new FileOutputStream(file); ObjectOutputStream oos = new ObjectOutputStream(fos); SerializeMe serializeMe = new SerializeMe("serialVersionUID is 1L"); ...
