example-egl build fails

[wilyarti]

I have followed the instructions as per the readme, but I can't build the example app.

I also am having problems building the nk-android example. I must have something missing in my environment. Any help appreciated.

The CompileOptions.bootClasspath property has been deprecated and is scheduled to be removed in Gradle 5.0. Please use the CompileOptions.bootstrapClasspath property instead.

Any help appreciated. I have written a nuklear app, and it runs on Linux/FreeBSD I am trying to get it to run on Android.
