catkin_make build failed kinetic android

Question

Hi, I'm trying to install Android along with kinetic ROS on Linux 16.04 LTS.

Once I get to the "catkin_make" step the build fails. I'm following this tutorial http://wiki.ros.org/android/Tutorials/kinetic/Installation%20-%20ROS%20Development%20Environment getting stuck on the last step of 3.1.

The first thing that failed was the address of my java directory. So I have to change it every time with export JAVA_HOME="/usr/lib/jvm/java-8-oracle/jre/ after that when I use the catkin_make the build starts and suddenly fails like this.

luis@luischd:~/android_core$ catkin_make

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 /opt/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.

FAILURE: Build failed with an exception.

* What went wrong:
A problem occurred configuring project ':android_10'.
> The SDK directory '/opt/android-sdk' does not exist.

If you are building for Android, you will need Android SDK.

You can download SDK versions inside Android Studio, which is the standard tool for developing apps. From the error, you need SDK version 10 to build it. On top of that, there's an environment variable that should point to where the SDK is installed, which is ANDROID_HOME. Be sure to set it properly to where you have your SDK installed (e.g. export ANDROID_HOME=/home/user/Android/Sdk).
