AlphaTrainer Android App

Download code from (clone or zip):

https://github.com/AlphaTrainer/AlphaTrainerAndroid/tree/finalhandin

Quick

Simply install the AlphaTrainerApp-debug.apk

$ wget https://github.com/AlphaTrainer/AlphaTrainerAndroid/raw/finalhandin/AlphaTrainerApp-debug.apk
$ adb install <path-to-apk>/AlphaTrainerApp-debug.apk

Build from scratch

** Prerequests **

We assume all Android tools (ADT) like adb, NDK ³, etc are setup.

OpenCV Android SDK 2.4.6 ⁴ and have it set in the build path:

$ ls $OPENCV_ANDROID_SDK
etc java    native

** Use the shell scripts **

$ cd <some dir that have a check out of opencvbrain>
$ ls
AlphaTrainerAndroid opencvbrain
...
$ cd AlphaTrainerAndroid
# step 0: build native lib stand alone
$ build_0_opencvbrain.sh
...
# step 1: build native lib into app with ndk
$ build_1_ndk_brainapp.sh
# step 2 build and install android app:
$ build_2_android_brainapp.sh

AlphaTrainerService

Runs at MongoLab ⁶ and Heroku ⁷: http://alpha-trainer.herokuapp.com/.

Mongolab cloud storage

Using the the version 2 beta we can for example query all feedback trainings and ignore the alpha_levels:

GET https://data-api.mongolab.com/v2/apis/dk5jpmcf2g1bg/collections/trainings
/documents?fields=%7B%22alpha_levels%22%3A0%7D&query=%7B%22type%22%3A%22Feedback%22%7D</code>

Last part not url encoded:

/documents?q={"type":"Feedback"}&fields={"alpha_levels":0}</code>

Reference the full API at http://alpha-trainer.herokuapp.com/.

AlphaTrainerService client

Download code from (clone or zip):

https://github.com/AlphaTrainer/AlphaTrainerService/tree/finalhandin

Download the Typesafe Activator a tool on top of the Play Framework ⁵. Ensure to have Activator in your build path:

$ which activator
<path to>/activator-1.0.0/activator

OK then start it:

$ cd <path to>/AlphaTrainerService
$ ./activator run
# listen to file changes use
$ ./activator ~run

And then open the client in a browser.
