I want to learn how to write code in Android NDK.
I open the 'android studio guide' and on the 'create new ndk project' I follow the instruction.
I just create new project and add support for C++ code and that's it .. all the IDE code is in red and nothing can be compile.
Can't find any problem and I don't know what to do.
Tried to sync by clicking 'Try again' in first - and still fail.
The error message is:

Thanks for any help.
Click on the "Try again" in yellow banner. If you got the error still probably problem is with you do not have necessary library packages in your build.gradle file. Check if you have added necessary Support Library Packages in your build.gradle file. If doesn't then add it and "rebuild" your project.
Your error message is:
CMake 3.6.0 or higher is required. You are running version 3.4.1
I do not know whether you have your own CMake installation or you are attempting to use one that comes from Android Studio. My guess is that you have your own CMake installation. If so, upgrade it to 3.6.0 or higher.

I tried to create simple android application with NDK support. I followed https://developer.android.com/studio/projects/add-native-code.html#new-project while creating project. After creating project it gives me following error:

I've installed CMAKE, LLDB, NDK. Can I get some help?
Thanks.
I think you need to install compiler driver of c++.
I have followed the instructions in this link: http://www.vtk.org/Wiki/VES/Developers_Guide
I have downloaded VES, Andoid ndk-r8b, Android Studio (which has Android sdk), adb, ant.
And following the instructions:
export ANDROID_NDK=/home/ahrgm/Downloads/android-ndk-r8b
cmake -P configure.cmake
cd build
make -j4
the following error appears:

How can I solve this problem?
I managed to build OpenCV 2.4.9 for java following the online instructions.
However I am unable to build for Android
I am using OSX Yosemite, CMake 3.0.2, OpenCV 2.4.9.
The output I get is the following:

I tried setting both:
export ANDROID_NDK=~/android-ndk-r8e
and
export ANDROID_STANDALONE_TOOLCHAIN=~/android-toolchain
but both give same error. Any clues to what is causing this? Bad version of CMake?
I am trying to build something using the Android NdK standalone toolchain. However, I am running into these errors.

There are two sets of errors. I have no idea where to begin with the first set. The android.toolchain.cmake file looks into sysroot by default but android is not installed there neither does Google require me to install it there.
Regarding the CMAKE variables, I found that most solutions involve installing Developer Tools, which I already have. I tried manually setting the CXX and CC variables but that did not help.
Any ideas as to where to start?
Thank you.
Ok, I'll do a bit of guesswork here, but I think you're using http://code.google.com/p/android-cmake/ and you're calling it with ANDROID_STANDALONE_TOOLCHAIN while providing it the path to your NDK. If I'm right, that's the problem.
You should either call it with ANDROID_NDK and provide the path to your NDK.
The android-cmake documentation suggests that this is the way to go.
or
Keep calling it with ANDROID_STANDALONE_TOOLCHAIN, but providing it the path to an installed toochain (something created with make-standalone-toolchain.sh)
If you want to go this way, you can find information about creating standalone toolchains in docs/STANDALONE-TOOLCHAIN.html in your installed NDK.
