android - using the tess-two library

Question

I am following this tutorial and manage to build the library just fine.

My State Now:

• I take a photo, save it to the external memory (here is the directory path)

  static String directoryPath = Environment.getExternalStorageDirectory().toString() + "/saved_images";
  

• In the directory there are currently only pictures I took in jpg format.

• I can load a bitmap from the saved image.

The problem-

I couldn't understand how do I use this piece of code:

TessBaseAPI baseApi = new TessBaseAPI();
// DATA_PATH = Path to the storage
// lang = for which the language data exists, usually "eng"
baseApi.init(DATA_PATH, lang);
// Eg. baseApi.init("/mnt/sdcard/tesseract/tessdata/eng.traineddata", "eng");
baseApi.setImage(bitmap);
String recognizedText = baseApi.getUTF8Text();
baseApi.end();

• What is the DATA_PATH variable?
• also read something about creating a folder named tesseract and putting there language files?

not really sure what I need to do and the tutorial doesn't explain it.

any help would be appreciated!

Answer 1

put the file in your devices (download folder for example)

Open the file properties in your devices:

and copy the path in your DATA_PATH var, for example: /mnt/sdcard/download/eng.traineddata

the TessBaseAPI need the file for initialization.
