Tesseract traineddata path

Question

I am trying to use tesseract-ocr in my android app. When I am trying to init() I get IllegalArgumentException because in this folder there is no 'tessdata' dir! Here is my project structure. project structure

Here I used InputStream and cacheDir:

private String getDirPath() {
    File f = new File(getCacheDir()+"/tessdata/");
    if (!f.exists()) try {

        InputStream is = getAssets().open("tessdata/eng.traineddata");
        int size = is.available();
        byte[] buffer = new byte[size];
        is.read(buffer);
        is.close();


        FileOutputStream fos = new FileOutputStream(f);
        fos.write(buffer);
        fos.close();
    } catch (Exception e) { Log.e("error", e.toString()); }
    Log.i("wtf", f.getPath());
    return getCacheDir();
}

To init the Tesseract I have to pass 2 arguments - path to dir which contains directory 'tessdata' and second one is traineddata. Any ideas?

have you add read files permission? – aldok May 01 '17 at 15:17 — aldok, May 01 '17 at 15:17

You can't refer to your app's raw asset files that way. Try using AssetManager instead.

Here! I edited my post with other way to get dir path. – May 21 '17 at 19:21
You edited your post to make it a completely different question. Please don't do that. – rmtheis May 21 '17 at 20:30

The path to your assets is

 Uri path = Uri.parse("file:///android_asset/")
 String dataPath = path.toString();
