Dear Li Perry,

Than you for contacting us.

You can customise the configuration file according to your neeeds. For instance, to choose the language you should modify the .conf file. You can refer to
https://developer.myscript.com/docs/interactive-ink/1.3/android/fundamentals/interactive-ink-runtime/#language-recognition-configuration

Modifying the configuration to use custom resources is a more advanced use case. You can refer to following page:
https://developer.myscript.com/docs/interactive-ink/1.3/android/advanced/custom-recognition/
to learn how to build your custom resources and use them.

If you want to modify the configuration dynamically, please check following topics that describes how to proceed:

Best regards,

Gwenaëlle

Dear Li Perry,

Thank you for your update.

If I come back to your question and example: "I directly pass in the code: "0123456789", he can directly recognize these numbers only. Instead of geneating .res first; then modify .conf, then package and install apk to run."

You can't directly pass the "0123456789": you must generate the corresponding the .res file and set a configuration file that refers to this resource file.
But you can do this AFTER the apk installation, dynamically in your application code thanks to the RecognitionAssetsBuilder API:
https://developer.myscript.com/refguides/interactive-ink/android/1.3/com/myscript/iink/RecognitionAssetsBuilder.html

This section describes step by step how to use the RecognitionAssetsBuilder inside your code to generate and use the .res file on device:

Hi,

Thank you for your update.

Let's assume you want to set a lexicon dynamically in your English US recognition.

Here is how you could proceed:

In the en_US.conf file that you package in your apk, you plan your customised resource that will be generated dynamically by adding the dir resource path with the line AddResDir /data/user/0/com.myscript.iink.getstarted/files

and by adding the customisedLexicon that your application will use dynamically. Depending whether you want to replace the English US lexicon to only recognize your custom lexicon or you want to enrich the English US lexicon with your custom lexicon, in which case you would also keep the

 AddResource en_US/en_US-lk-text.res in your  customisedLexicon, this would look like:

Bundle-Version: 1.0
Bundle-Name: en_US
Configuration-Script:
 AddResDir ../resources/
 AddResDir /data/user/0/com.myscript.iink.getstarted/files

Name: text
Type: Text
Configuration-Script:
 AddResource en_US/en_US-ak-cur.res
 AddResource en_US/en_US-lk-text.res
 EnableAlienCharacters
 SetTextListSize 1
 SetWordListSize 5
 SetCharListSize 1

Name: customisedLexicon
Type: Text
Configuration-Script:
 AddResource en_US/en_US-ak-cur.res
 AddResource customised-lexicon.res
 EnableAlienCharacters
 SetTextListSize 1
 SetWordListSize 5
 SetCharListSize 1

Then the method in your app to generate and use the customised Lexicon, could be:

private void updateLexicon()
  {
    Editor editor = editorView.getEditor();

    String internalStoragePath = getBaseContext().getFilesDir().getPath();

// 1. Create a recognition assets builder
RecognitionAssetsBuilder assetsBuilder = engine.createRecognitionAssetsBuilder();

// 2. Define and compile the lexicon: here it contains two words Johnson and Meyer
String lexicon = "Johnson" + "\n" + "Meyer" + "\n" +  "Lopez" ;

    assetsBuilder.compile("Text Lexicon", lexicon);

// 3. Save it to the disc
File file = new File(internalStoragePath, File.separator + "customised-lexicon.res");
    Log.d(TAG, "creating resource file  \""  + file.getPath());
try {
      assetsBuilder.store(file.getPath());
    }
catch(IOException e){
      Log.e(TAG, "Failed to save custom lexicon  \""  + e.getMessage());
    }

// 4. Update editor conf to take this resource into account. NB the conf shall be updated before setting the part of the editor.

if (contentPart != null)
    {
      contentPart.close();
      contentPart = null;
    }
    contentPart = contentPackage.getPart(0);
if (contentPart != null)
    {
      contentPart.close();
      contentPart = null;
    }
    editor.setPart(null);
    editor.clear();

    Configuration conf = editor.getConfiguration();
    conf.setString("text.configuration.name", "customisedLexicon");

    contentPart = contentPackage.createPart("Text");

    editor.setPart(contentPart);


  }

Just and additional warning, if you plan to re-use several times the res file with same name;

When building a dynamic lexicon, resource happens to be loaded in  memory. It shall then be released before re-compiling it. To proceed,  one solution can be to set the default "text" configuration: https://developer-support.myscript.com/support/discussions/topics/16000026598

• set Default Text configuration =>this releases the resource from memory
• add word to the lexicon and compile the resource
• load the configuration

Best regards
