I'm looking to start developing android applications and I need to know if the HDX (I have one) has an ARM processor. I can't seem to find that information online. Any help is appreciated. Thank you.Kindle Fire HDX 7", HDX Display, Wi-Fi, 16 GB - Includes Special Offers

I'm not sure where you'd find that. You may have luck asking here:

Brittany D, on a quick search I found a page which lists that yes, the Qualcomm Snapdragon 800 processor used in the HDX is an ARM processor. At the bottom of the page this review shows the various products the processor is used in. Some various WIKI pages/links indicate it is an ARM processor as well but given it's nature I don't tend to rely on anything found in any WIKI pages/links. The page I found is at:
http://www.notebookcheck.net/Qualcomm-Snapdragon-800-MSM8974-SoC.103706.0.html

Edit: Testing to see if my link to a non-Amazon link showed up. Typo.

Thank you, Soulrider. I am not familiar with processors and hardware in general so trying to read through specs and information wasn't getting me anywhere. Thank you for verifying my suspicion. I am not yet sure how I would need to work around an ARM processor with Android coding but I will continue looking into learning how to make apps. Thank you for checking for me, Soulrider. I appreciate it. :)

Brittany D, you're very welcome. I can't really help on the coding side of things (I haven't done any coding in a LONG time) but I'm glad you at least got the processor question answered.

You don't "work around" an ARM processor with Android coding. Android programs are written in Java, which is then compiled into an Android-specific object code. You cannot write machine-level code so it makes absolutely no difference what processor your app will be running on.

All you need to know is the Android version and hardware characteristics like screen size and resolution, and if you need special hardware like GPS or accelerometers, whether those are available on the device you're targeting.

Android app development - I think you need to get a basic book on this topic,
as then you will realize that the Android world uses Java apps and the JVM -
which means you are totally insulated from the actual hardware.
The apps only need to know what Android version and API version you require for supporting your app....

Lastly - the latest version of Android - L - might change from a JVM and JIT to a pre-compile world...

Actually Android code does not run on JVM or use JIT compilation. It uses a runtime engine called "Dalvik" which is why Java code must be refactored before it can run on Android devices.

The proposed change is to another non-Java runtime engine called ART, which does do JIT compilation.

Pre-compiled code is never likely to be practical on an OS like Android due to the number of different processors that must be supported.

I was trying to keep it simple for the OP, with concepts & terms she might have heard....

Seriously? JVM and JIT? Riiiiight.
