- The latest version of the SDK is available for Windows, OS X and Linux here.
Which hardware devices support Android?What is Dalvik? How is it different from JVM?
- You can start writing applications even if you don?t have hardware to run them on. The Android SDK comes with an emulator and all tools necessary for application development and deployment.

How can I view PDFs and Office documents?Which Android versions are being used out in the field?Is Android code compiled to a .class file?
- The NDK (Native Development Kit) gives developers the ability to call into native code from Android applications. There is a Google group for NDK-related discussions. At present, Android supports libc, libm, JNI interface headers, libz, liblog, OpenGL ES 1.1 and OpenGL ES 2.0, libjnigraphics, a minimal set of headers for C++ support, OpenSL ES native audio libraries and Android native application APIs.
I want to write Android Applications too but dont know where to start?Do Android projects have deployment descriptors?My Application throws an Exception, where is the Stack Trace dumped?
- The Java bytecode of a compiled class is converted into Dalvik executables or (.dex) files, using the "dx" tool bundled with the SDK . The application is packaged into .apk file which are zipped .dex files. The Dalvik virtual machine runs Dalvik executables in the apk file.
What functionality of the actual device can the emulator emulate?
- Exceptions are written to a log file, named Logcat in the emulator. You can obtain a dump by executing the adb logcat command. To write log messages from your application, use the static methods of JavaDoc:android.util.Log class(Log.v(), Log.d(), Log.i(), etc.). If you are using Eclipse with ADT plugin, you can open "Logcat" view to see the logged messages.
