StoryPath Framework

Bundling Sample Application Data

The sample module requires a complement of data that will be delivered in production via a Google Play APK Expansion File. To create and transfer this data to your device during development use the bundled content.py script:

python content.py clone
python content.py generate_json
python content.py zip_content
python content.py adb_push_files

As work progresses on the liger data repository you can update your repository and re-bundle the APK Expansion File:

python content.py pull
python content.py generate_json
python content.py zip_content
python content.py adb_push_files

Testing

Espresso Testing:

To run the test suite, you simply need add the correct instrumentation runner to the Run config. In Android Studio, open the 'Run' -> 'Edit Configurations' -> 'General tab.' Expand 'Android Tests' on the left and click 'LearningGuideTest' or 'DefaultLibraryTest'. Under 'Specific instrumentation runner (optional)', paste the following: com.google.android.apps.common.testing.testrunner.GoogleInstrumentationTestRunner. Prior to testing, a current obb file (renamed to main..scal.io.liger.test.obb) must be placed in the scal.io.liger.test files folder. Also, the files SAMPLE.jpg, SAMPLE.mp3, SAMPLE.mp4, SAMPLE.png must be placed in the same folder (copied/renamed from the example files in learning guide 1)

Additional card types

These were created to support aspects of the prototype, and don't necessarily correspond to any of the card types described in the design documents.

Clip type card fields:

references - string value, must equal scal.io.liger.ClipTypeCardModel
clip_types - array of string values, a list of supported media types

Quiz card fields:

references - string value, must equal scal.io.liger.model.QuizCardModel
description - string value, text to display on the card, most likely a question
options - array of string values, a list of possible answers to a question

Quiz report card fields:

references - string value, must equal scal.io.liger.model.QuizReportCardModel
description - string value, text to display on the card, most likely feedback on the quiz results
results - array of string values, references to options selected in previous quiz cards

this field is obsolete now that the "references" field has been added to the base class

Video capture type card fields:

references - string value, must equal scal.io.liger.model.VideoCaptureTypeCardModel
body - array of widget structures, see possible formats below

these widgets will be objects with functionality such as media capture or image display

Video capture widget fields:

references - string value, must equal scal.io.liger.widget.VideoCaptureWidget
camera_references - string value, the camera type to use for the capture, most likely front/back

Markdown widget fields:

references - string value, must equal scal.io.liger.widget.MarkdownWidget
text - string value, markdown text to display on the card

Android flips bold and italic from the markdown standard in the textview for some reason. Also, here is the subset of HTML and hence Markdown that is supported: HTML Tags Supported By TextView

Image widget fields:

references - string value, must equal scal.io.liger.widget.ImageWidget
path - string value, the path of an image file to display on the card

Sample YAML:

---
  id: story_path
  title: Story Path
  cards: 
    - 
      type: scal.io.liger.model.VideoCaptureTypeCardModel
      id: video_capture
      title: Video Capture
      body: 
        - 
          type: scal.io.liger.widget.MarkdownWidget
          text: Some markdown text here
        - 
          type: scal.io.liger.widget.ImageWidget
          path: file:///sdcard/foo.jpg
        - 
          type: scal.io.liger.widget.MarkdownWidget
          text: Some more markdown
        - 
          type: scal.io.liger.widget.VideoCaptureWidget
          camera_type: front
        - 
          type: scal.io.liger.widget.MarkdownWidget
          text: Final markdown

Sample JSON:

this covers the video capture type card only, the other card types are generally similar to those covered in the previous example.

{
  "id": "story_path",
  "title": "Story Path",
  "cards": [
    {
      "type": "scal.io.liger.model.VideoCaptureTypeCardModel",
      "id": "video_capture",
      "title": "Video Capture",
      "body": [ 
        { 
          "type": "scal.io.liger.widget.MarkdownWidget",
          "text": "Some markdown text here"
        },
        { 
          "type": "scal.io.liger.widget.ImageWidget",
          "path": "file:///sdcard/foo.jpg"
        },
        { 
          "type": "scal.io.liger.widget.MarkdownWidget",
          "text": "Some more markdown"
        },
        { 
          "type": "scal.io.liger.widget.VideoCaptureWidget",
          "camera_type": "front"
        },
        { 
          "type": "scal.io.liger.widget.MarkdownWidget",
          "text": "Final markdown"
        }
      ]
    }
  ]
}

Tips

To convert YAML to JSON before you push to your phone to test, you can run a command like this:

python -c 'import sys, yaml, json; json.dump(yaml.load(sys.stdin), sys.stdout, indent=4)' < my.yaml > my.json

Then you can push this to your phone for testing:

adb push my.json  /sdcard/Liger/

Create a credentials file for the Google Play API:

vim ./lib/src/main/res/values/google_play.xml

The file must include the public key belonging to your publisher account. You can find the key in the Developer Console under your profile information. You must also provide a string containing an array of random bytes that will be used for obfuscation.

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="base64_public_key">REPLACE WITH YOUR PUBLIC KEY</string>
    <string name="liger_salt">REPLACE WITH A STRING OF BYTES</string>
</resources>

Android Iconify

Liger utilizes icon webfonts instead of the traditional path of generating multiple drawables per screen resolution. Here are the steps to creating/editing icons:

Generate your desired icons in SVG format
Convert your SVG files to a .TTF file

There are several ways to do this online. We use the command line tool Font Custom

After generating your .TFF file, you need to make 3 changes:

Add your .TFF file to the android-iconify folder "src/main/assets/"
In "Iconify.java", change the 'TFF_FILE' variable to reflect your new file
```
private static final String TTF_FILE = "YOUR_FILE_NAME.ttf";
```
Still in "Iconify.java", change 'IconValue' variable to include your font names and unicode values
```
public static enum IconValue {
    fa_clip_ex_action('\uf145'),
    fa_clip_ex_character('\uf146');
}
```
Here is a small script to help quicken the process of converting the generated "fontcustom.css" to a usable Enum list in "Iconify.java"

Note: Your enum keys must begin with "fa"

You are now ready to use your new icons

<IconTextView
android:text="{fa-clip_ex_action}"
android:shadowColor="#22000000"
android:shadowDx="3"
android:shadowDy="3"
android:shadowRadius="1"
android:textSize="90dp"
android:textColor="#FF33B5E5"
... />
