Tess two and tessdata folder

Question

I am developing an Android ocr app with the tess-two library. While testing I manually copied the tessdata folder in my test device but now I need a programmatically way to do it. How the other apps do? Is it necessary to copy the folder or can I do in other ways? Thank you

Answer 1

You can do this programmatically. I would advice you give you android app Permission to access the phones memory so that you can copy this data on load.

here is a sample code I used for a project

protected static final String PHOTO_TAKEN = "photo_taken";

path = DATA_PATH + "ocr.jpg";

    String[] paths = new String[] { DATA_PATH, DATA_PATH + "tessdata/" };
    for (String path : paths) {
        File dir = new File(path);
        if (!dir.exists()) {
            if (!dir.mkdirs()) {
                Log.v(TAG, "ERROR: Creation of directory " + path + " on sdcard failed");
                return;
            } else {
                Log.v(TAG, "Created directory " + path + " on sdcard");
            }
        }

    }
