Build LibVLC Android Demo Application

[lanamelach]

I have been trying to build VLC for Android on Ubuntu 16.04 following to this guide:
https://wiki.videolan.org/AndroidCompile

At the "Setup Gradle build system" step when I run compile.sh it fails:

...
:api:prepareReleaseDependencies
:api:compileReleaseAidl
:api:compileReleaseRenderscript
:api:generateReleaseBuildConfig
:api:mergeReleaseShaders
:api:compileReleaseShaders

:api:incrementalReleaseJavaCompilationSafeguard
:api:compileReleaseJavaWithJavac
:api:compileReleaseJavaWithJavac - is not incremental (e.g. outputs have changed, no previous execution, etc.).
:api:compileReleaseJavaWithJavac FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':api:compileReleaseJavaWithJavac'.
> Could not find tools.jar

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

BUILD FAILED

At /usr/lib/jvm I found these folders:
default-java
java-1.8.0-openjdk-amd64
java-8-openjdk-amd64

It seems like none of them contains tools.jar. What am I missing?
Just in case, I use a clean Ubuntu machine, so there is nothing installed but those things mentioned in the guide and default software.

Ok, solved it. Now trying to build the LibVlc Android Demo:
https://bitbucket.org/edwardcw/libvlc-android-sample

Compilation fails with the following error:
