Hello,

I am wondering what the planned support for Android x86_64 is, and when it will be available?

Looking at the current version, there is no cmake_android_x86-64.sh file for building.

Thx,

-k

OpenCV for Android is built using Android NDK. Do you know anything about NDK version supporting compilation for Android x86_64?

Yes, I have access to a 64-bit NDK.

I thought there's was no plan to release such platform in android and there's not such device actually, why should you need that ?

In iOS , it's available only for simulator that works very differently from android ( that is, the simulator does not emulate hardware but software )

64-bit android for Baytrail devices are available, and more are coming. Also 64-bit ARM devices will be available Q4/early Q1 '15.

ARM is not x86 , they are completely different processors, you'll never need to compile x86_64 to run or debug an android app

Yes, I know that ARM is not x86. The point I was making is that 64-bit is coming to BOTH platforms, so OpenCV needs to be available for those platforms; I was specifically requesting x86_64 support. Android apps will compile to 64-bit under both Dalvik and ART automatically once those VM's have been ported, but native code (OpenCV-based shared libraries, etc.) will need to be compiled against the 64-bit NDK/OpenCV toolchain.

Strange that intel that produces x86-64 and develops opencv did not know about this.

It's no longer true: http://www.phonearena.com/news/The-64...
