Make travis works with android, JavaFx, and Js

[gzoritchak]

Travis CI fails on android configuration:

* What went wrong:
A problem occurred evaluating project ':app'.
> The SDK directory '/Users/gaetan/Library/Android/sdk' does not exist.

See https://stackoverflow.com/questions/27644586/how-to-set-up-travis-ci-with-multiple-languages
and https://docs.travis-ci.com/user/languages/android/

I can give this one a try

You're welcome.

By default, android modules are not activated (see https://github.com/data2viz/data2viz/blob/master/gradle.properties#L8). Changing that property to true makes all android gradle projects activated. They are mainly the android version of some module but there is also two applications.

examples/app is the code of https://play.google.com/store/apps/details?id=io.data2viz.data2canvas

and viz/rendering-app is used to test the rendering on android (see https://youtu.be/jnUtiyrpBCY?t=1637)

I tried something there: martinbonnin@4e233b2.

For some reason travis-ci.org does not see my repo yet so cannot test yet. I'll update this thread if it ever works

@gzoritchak I'm trying to do this via Travis' build matrix, does the project have an easy way to run a task against subprojects with a specified platform only (-android in this case)?

UPDATE: I found a solution for this, still plugging away at other issues.
