Hello Praneeth,I believe there is quite a step from these micrcontrollers to a full blown application processor running Android.Debugging and tracing features are much more advanced, and is using the industry standard called JTAG.You can buy a JTAG adapter from ARM (http://arm.com/produ...pters/index.php) and from third parties. You can also look at open source to build your own JTAG target.If you want to start on similar products to the ones you mentioned, you can look at the ARM Cortex-M family of processors used in microcontrollers. If you wish to run Android on a recent processor, you will look at the ARM Cortex-A series. The ARM Cortex-A Programmer's Guide would be a good way to start.Alban
