I'm a beginner in Android. My friend heard "Neon". So I did Google and found this
Referring it, Neon is related to multimedia for Android OS or all mobile OS, is it? Please share me more.

The NDK supports ARM Advanced SIMD, commonly known as Neon, an optional instruction set extension for ARMv7 and ARMv8. Neon provides scalar/vector instructions and registers (shared with the FPU) comparable to MMX/SSE/3DNow! in the x86 world.
Arm Neon is an advanced single instruction multiple data (SIMD) architecture extension for the Arm Cortex-A and Arm Cortex-R series of processors with capabilities that vastly improve use cases on mobile devices, such as multimedia encoding/decoding, user interface, 2D/3D graphics and gaming.
Neon is an ARM co-processor, meant for vector processing. Neon is used for multimedia data processing. It is an optional co-processor, the Android Linux kernel may or may not have support for this. (Eclair days)
However if Google provides any Android Application APIs to access Neon, then you can safely use it in your application.

NEON is extremely powerful and easy to program. It doesn't solve performance issues, but simply eliminates them in most cases.
NEON intrinsics suck performance-wise, I suggest writing native codes for NEON.
Honestly, I'm not exaggerating in any way. NEON is THAT powerful.
