Hi, downloaded your aerogear-android-cookbook
and tried to build the embedded ShootandShare project.

Getting an exception when buildiing from the Jack transform task, see below

Internet search is telling me Jack toolchain is now deprecated.

App is using Java 1.8 features like lambda functions, necessitating Jack.

I think a new demo app needs to developed without Jack and without Java 1.8 features, they are irellevant to your goal of demonstrating your libraries,

Caused by: com.android.sched.util.config.PropertyIdException: Property 'jack.library.output.dir' (in Options): 'case insensitive wrapper' VFS format in directory '/Users/danielleahy/Development/projects/android/aerogear-android-cookbook/ShootAndShare/app/build/intermediates/incremental/transformJackWithJackForDebug' is wrong: file '/Users/danielleahy/Development/projects/android/aerogear-android-cookbook/ShootAndShare/app/build/intermediates/incremental/transformJackWithJackForDebug/index' does not exist (required because 'jack.library' (defined in Options) is set to true and 'jack.library.output.container' (defined in Options) is set to 'dir')
