New Cocos2d-x Android project gets error!

I created new project with Cocos2d-x, and compile it then... Error! 2 solutions in this case.

What's happend

Executed command.
$ cocos compile -s ./TestingProject -p android
Thanks for the reply.
make: /Users/(UserName)/Android/android-ndk-r11c/toolchains/arm-linux-androideabi-4.8/prebuilt/darwin-x86_64/bin/arm-linux-androideabi-g++: No such file or directory
make: *** [obj/local/armeabi/objs-debug/cocostudio_static/WidgetReader/WidgetReader.o] Error 1
make: *** Waiting for unfinished jobs....
Error running command, return code: 2.

Environment

Java SE Development Kit 8u92
Cocos2d-x 3.10
Android Studio 2.1.1 (SDK API level 23)
Android NDK r11c
Apache ANT 1.9.7

The solution A

Make "RELEASE.TXT" in NDK folder as other NDK version.
/android-ndk-r11c/RELEASE.TXT

Just write this below without anything else.
r11c (64-bit)

The solution B

Download Android NDK r10e.
https://dl.google.com/android/repository/android-ndk-r10e-darwin-x86_64.zip

Rewrite .bash_profile. It is NDK_ROOT path to r10e from r11c.
You can edit this from terminal because of this is hidden file.
$ open -e /Users/(UserName)/.bash_profile
Do not forget this command after that.
$ source /Users/(UserName)/.bash_profile
