Bixby Developer Center

The Bixby viv.shareVia library capsule allows your capsule to send content to other applications, using Android intents. The library provides access to the Android share menu, which lets the user choose a target application to send the shared data to and returns a target name to your capsule.

A sample capsule that uses viv.shareVia is available as library-share-via-example in the Bixby Capsule Samples Collection on GitHub.

Models

AppInfo

The AppInfo concept contains sharing target activity information. This can be used by your capsule to determine both the application to send data to and the specific data to send.

SelectAppResult

This structure contains metadata about whether an application was successfully selected for sharing via the share screen.

1. This field contains either the string result_type_success, when an application to share with has been selected, or result_type_fail, in all other cases.
2. This field offers more description about the failure or success state. It contains one of the following:
   1. result_desc_matched: an application has been selected and the appInfo field has been populated. This will be the value if the result type is result_type_success.
   2. result_desc_not_matched: Bixby could not find an application to share data with.
   3. result_desc_matched_more_than_one: more than one possible application to share with was returned.
   4. result_desc_not_exist_search_query: the SearchQuery field was empty.

IntentInfo

This concept is sent to your capsule's action endpoint along with SelectAppResult.

IntentExtraInfo

One or more of these structures can optionally be included in IntentInfo to pass data in the form of key/value pairs.

SearchQuery

This primitive name concept is used for training purposes.

Training

Usage

Your application should implement an action that outputs an IntentInfo concept. One way to do this is to extend IntentInfo and implement a FindIntentInfo action:

structure (IntentInfo) {
  extends (shareVia.IntentInfo)
}

action (FindIntentInfo) {
  type (Constructor)
  collect {
    // ... inputs from your capsule ...
  }
  output (IntentInfo)
}

Your actions might also create IntentInfo as a computed-input.

The shareVia.SearchQuery primitive concept is provided for training purposes, to allow your capsule to respond to utterances such as "share via Facebook":

[g:viv.yourcapsule.shareVia] Share via (Facebook)[v:viv.shareVia.SearchQuery]

There are no actions in viv.shareVia that implement searching on SearchQuery; if you use it as an input for FindIntentInfo (or your capsule's equivalent), you must provide an appropriate domain-specific implementation.

The final step of implementing sharing is to add a client endpoint for the sharing action itself. In your endpoints.bxb file, add an action-endpoint block that will receive the IntentInfo and SelectAppResult concepts:

action-endpoint (ShareVia) {
  accepted-inputs (intentInfo, selectAppResult)
  client-endpoint {
    input-mapper (capsuleInputMapper.js)
  }
}

Your capsuleInputMapper.js file should pass the appropriate data to the application specified in the appInfo property of selectAppResult. This can be done by returning an application-specific URI:

// defined by the client application's intent filter; see
// https://developer.android.com/training/app-links/deep-linking
const scheme = "intent";
const host = "com.sec.android.your_app";

module.exports.shareContents = function (intentInfo, selectappResult) {
  var uriType = "punchOut";
  var actionId = "share_action";

  var resultType = SelectAppResult.selectAppResultType;
  var resultDescription = SelectAppResult.selectAppResultDescription;
  var params = "?package=" + selectAppResult.appInfo.packageName;
  var uri;

  if (resultType == "result_type_success") {
    params += "&activity=" + selectAppResult.appInfo.activityName;
  }
  else {
    params += "&error=" + resultDescription;
  }
  uri = scheme + "://" + host + "/" + actionId + "/" +_ uriType + params;
  return {
    uri: uri
  }
}
