Regarding the storage directory of identification resources, configuration-manager.search-path

Hello, there is a scenario where I don’t want to use recognition resources (in Assets) inside the app.


I tried several methods and checked the corresponding documents, but the words were rather vague.


How should I configure the identified resource path to make the identified SDK work properly?


try code:

//...

engine = IInkApplication.getEngine();

    String path = "/storage/emulated/0/recognition-assets/conf/en_US.conf";

// String path = "/storage/emulated/0/myscript-iink-recognition-text-en_US.zip";

    File file = new File(path);

    // log

    LogConMgrUtil.getInstance().e("file exists : "+file.exists());

    // configure recognition

    Configuration conf = engine.getConfiguration();

    String confDir = "zip://" + getPackageCodePath() + "!/assets/conf";

    path = "zip://" + path + "!/assets/conf";

 

    conf.setStringArray("configuration-manager.search-path", new String[]{path});

    String tempDir = getExternalFilesDir(null).getPath() + File.separator + "tmp";

    conf.setString("content-package.temp-folder", tempDir);

    LogConMgrUtil.getInstance().e("confDir : "+confDir);

    setContentView(R.layout.activity_main);

//...

Dear Xp Pen,


Please find the way I proceeded to deploy and use the resources from the sdcard (in my case, I used the ko_KR language).

First, deploy the resources and conf file in the sdcard:

-Create the /sdcard/MyScript/assets/ directory

-from the latter, create a "conf",  directory

-adb push the ko_KR.conf file in the latter

-from the /sdcard/MyScript/assets/ directory, create the resources/mul directory

-adb push the mul-lk-english_secondary_2.res file in the latter

-from the /sdcard/MyScript/assets/ directory, create the resources/ko_KR directory

-adb push the ko_KR-ak-cur.res and ko_KR-lk-text.res resources in the latter


In your project:

-In the AndroidManifest.xml file, add the read and write external storage permissions:

    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />


In your code, set the confDir and ko_KR language:

    String confDir = "/sdcard/MyScript/assets/conf";
    conf.setStringArray("configuration-manager.search-path", new String[]{confDir});
    String tempDir = getFilesDir().getPath() + File.separator + "tmp";
    conf.setString("content-package.temp-folder", tempDir);
    conf.setString("lang", "ko_KR");


Start your application:

-In the logcat, you shoul have an error message indicating it is not able to load the ko_KR.conf file ; the reason is your application doesn't have the "File and Media access"

-To solve this, go to "Settings-> Apps & notifications" and select your app (e.g. iink GetStarted)

-Open the "Permissions"


-Allow "Files and media"

You shall now be able to load and use the ko_KR language.


Let us know if you have any question.


Best regards,


Olivier

thank you
