Tesseract traineddata path

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?

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

The path to your assets is

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