The answer is yes.  Gradle is the accepted standard.

For introducing current Android developers to Kawa, gradle would be
the path of least friction.

The minimal "kawaBuild" task from this gradle file should still work:

https://github.com/rafleon/KawaDroid/blob/master/app/build.gradle

preDexDebug doesn't exist in gradle anymore, so the new dependency is:

project.afterEvaluate{
    compileDebugSources.dependsOn kawaBuild
    compileReleaseSources.dependsOn kawaBuild
  }

That should do it. I haven't pushed updates to github in awhile.

Gradle has some faults (slow, complicated, bloated, etc), but it is
indeed the current Android standard.
They are legitimately working on improving it, so it should be fine eventually.
For example, this new feature is an enormous step in the right direction:

http://tools.android.com/tech-docs/instant-run

Instant Run pushes fresh compiled classes into the context of a
running mobile app.
It is not immediately obvious what the relationship could be between
Instant Run and a Kawa REPL,
but interesting tricks should be possible once the official build
tools are stable.
