Introduction to Android

  1. Actually android itself is not an Operating System,
  2. Inner level OS is Linux,over the linux Android is loading.
  3. Android is devoloped by Google , so google provide core libraries.
  4. It is a java oriented platform for devoloping and excecuting mobile applications.
  5. We can write programs in java and utilise android classes and API's.
  6. Applications and libraries mainly concentrated in mobile devices.
  7. Android applications can excecute in mobile device  with Android platform.
    •   ipod
    •  TabletPC
    •  PDA
    •  Embedded System ( Dedicated special purpose System)
  8. In embedded field lot of limitations for Android devolopment.

    • Direct access to H/W is difficult in application level.
    • We have to write driver programs for accessing H/W ( GPIO-general purpose I/O).
    • After modifiying the Source Code and including the driver , recompile the OS and create image.

    For biginning the Android development the following packages are needed.

    • 1. JDK                                - java development kit
    • 2. Android SDK                  -Software Development Kit.
    • 3. Android Platform and Platform Tool                                                                                            (It can be downloaded with Download manager available with Android SDK.)
    •  Eclipse IDE                        -Integrated Development Environment ( or any other IDE)
    •  Android ADT                     -Android Development ToolKit for Eclipse

BEAGLE BONE BLACK FOR EMBEDDED APPLICATION

Happy news for embedded developers, with the introduction of BeagleBone Black credit card sized single board 1GHz computer.We can develop high end embedded system with Operating system support in the ARM7 platform.Processor from Texas Instruments AM335x Cortex A8 Sitara . Advantage of this small system is many more ,it will operate on 5V dc supply with 500 MA,so with USB cable connected to 5v source can operate the system.Most of the desktop computer features available with this board.As a standalone system keyboard and mouse can be connected with USB.Out put display available at micro HDMI port,that can be connected to any latest TV with HDMI input.LAN port is provided for network access.USB device(slave) port also available for connecting with PC,the board will act as storage device.Same time there is an internet pass-through via USB.For the starting of development some startup file provided in the eMMC (on board flash memmory 2GB),by opening the file it will direct to beagleb
