Cannot compile bazel needed for tensorflow-android

I'm trying to explore the tensorflow android demo. I want to adapt the app using android studio.
However when I simply follow the instructions I get compilation errors no matter what I do:
Trying to compile tensorflow using bazel and NDK r12b:

No luck so far :-/. Has anyone successfully compiled tensorflow for android from source?
What version of Tensorflow, NDK, bazel, java are required / compatible with each other? Do I really need bazel? (never worked with it anyway) Can't I just compile the android demo in android-studio like any other app?
I'm using Ubuntu 14.04, Cuda8.0, cudnn_v5.1, Titan X Pascal (not sure if these things matter)

Installing Bazel on Ubuntu can be done without compiling.
Follow all steps of the dedicated documentation: Install Bazel on Ubuntu

I work with Telerik-AppBuilder visual Studio 2015 extension(kendo-ui) my android phone is Samsung Galaxy Star Duos GT-S7262 version 4.1.2
any help please and thanks
update:
I have folloewed this link [https://github.com/Telerik-Verified-Plugins/Mapbox] but I get this error:1
C:\Users\Admin>cordova plugin add https://github.com/Telerik-Verified-Plugins/Mapbox --variable ACCESS_TOKEN=my.access.token
Current working directory is not a Cordova-based project.
I have installed the cordova-plugins with npm,but I still get the problem :(

So the question boils down to: how in Visual Studio do you provide Cordova variables to plugins?
(You tried adding the plugin from the c:/users/admin folder which is not your project folder, that's why the Cordova CLI said: "Current working directory is not a Cordova-based project.")
I'm assuming you're using the AppBuilder extension for Visual Studio. If so, please read this doc, especially about how to configure variables:
http://docs.telerik.com/platform/appbuilder/creating-your-project/using-plugins/using-verified-plugins/install-verified-plugins

Can't build streamer tutorial for android on mac

Can't build streamer tutorial_3 for android on mac
I,ve got all environment variables needed.
My eclipse can't to resolve some symbols, but to some of them i can get by pushing F3. It's very strange for me.
Here is the command line output:
23:04:06 **** Build of configuration Default for project Tutorial3 ****

23:04:10 Build Finished (took 3s.740ms)*
I use ndk-10r and gst-1.4.0.
I know that there is no interfaces/xoverlay in new streamer.
EDIT
I've built ok, but steel got underlines of many glib-types and GST-macross. Here is a screenshot:
what is interesting that i have no underlined headers, for example: i've include pthread.h but have got underlined pthread_t and phtread_key_t....
i think that i have not install some general libraries on my mac, something like libc or what ever...may it couse this problem? The problem is that i can't run my app from eclipse. and for more: i use DS-5 CE IDE

This is most likely because we build the android 1.4.x cerbero packages with the r9d NDK.
You might want to use the r9d NDK until we provide binaries built with a more recent NDK (started some builds to see if everything goes through fine).

I couldn't find the cause. Would someone help me?
I have asked this same question on Xamarin.Android's forum, and still waiting for their answer. But i think i could gather more resources and insights from experts here.

It's a recent change/bug in Xamarin.Android that expects to be used with Android tools rev. 22 or later where appt has been moved around in the sdk directory (from tools to build-tools). You need to go into the android sdk manager and update the SDK tools to revision 22 (or better) and also install the new build-tools package.
