Gradle build

[Aaargh20318]

I added a few Gradle build scripts to build tess-two and (optionally) publish the resulting library as an AAR to a maven repository. This does not use the new Gradle plugin with NDK support as that doesn't seem to be working for this case yet, instead it calls the existing ndk-build.

Awesome. I'll check this out and merge it. I may see about merging it on a separate branch while the new Gradle plugin with NDK support in Android Studio has its kinks worked out a bit more.

I'm planning to modify this to work with the experimental Gradle plugin instead of using a separate command-line build step.

I tried that at first but I ran into issues with the experimental plugin, can't remember exactly what the issue was though.

Have either of you had luck using the experimental plugin? I'm thinking of giving it a shot this week.

[rmtheis]

@jschear Nope. I've spent some time on it but I haven't gotten it to work.

[ArjanSchouten]

@jschear I wasn't able to use it too. Think we've to wait for official support in gradle and Android Studio.

[jschear]

Ah, too bad. Thanks!

If you want to give it a shot, by all means, have at it. Give me a holler on email if I can help with anything.
