Could not find Android Tools Plugin Gradle:2.3.3 while building guest_science_manager

[eran0926]

Hi!
I have encountered an error while building guest_science_manager following running_gs_app.md

Here is the error log:

FAILURE: Build failed with an exception.

* What went wrong:
A problem occurred configuring root project 'guest_science_manager'.
> Could not resolve all dependencies for configuration ':classpath'.

I think the reason of this is same to the issue #71 .
I've tried simply replace all jcenter in core_apks/guest_science_manager/build.gradle to mavenCentral and change gradle version to 2.3.0,
but there still some error occurred.

NDK is missing a "platforms" directory.
If you are using NDK, verify the ndk.dir is set to a valid NDK directory.  It is currently set to /home/astrobee/Android/Sdk/ndk-bundle.
If you are not using NDK, unset the NDK variable from ANDROID_NDK_HOME or local.properties to remove this warning.

Errors during XML parse:
Additionally, the fallback loader failed to parse the XML.
