Ошибка Android Tesseract. Файл данных не найден в ⇐ Android

[Anonymous]

Я изучаю Android, используя NDK с OpenCV. < /p>

Я успех с использованием NDK. Итак, я получаю использование данных (я имею в виду, что данные были сделаны с помощью Canny.) /> Производилась эта ошибка.

Я уже проверил adroid/app/src/main/assets/tessdata/eng. Пожалуйста ... < /p>

public class ocrActivity extends AppCompatActivity {

private static final String TAG = "opencv";
private Mat matInput=new Mat();
private Mat matResult=new Mat();
private Mat matFinal=new Mat();
public Uri luck;
public Bitmap testbm;
public Bitmap resultbm;

public native void ConvertRGBtoGray(long matAddrInput, long matAddrResult);

static {
System.loadLibrary("opencv_java3");
System.loadLibrary("native-lib");
}

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON,
WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);

setContentView(R.layout.activity_ocr);
ImageView iv1 = findViewById(R.id.imageview01);

Uri data = null;

Intent takePhoto = getIntent();
String flag = takePhoto.getStringExtra("flag");

if (flag.equals("imageUri")) {
data = takePhoto.getParcelableExtra("imageUri");
} else if (flag.equals("albumURI")) {
data = takePhoto.getParcelableExtra("albumURI");
}

luck = data;
testbm=test123();
//

Utils.bitmapToMat(testbm,matInput);

if ( matResult == null )
matResult = new Mat(matInput.rows(), matInput.cols(), matInput.type());

ConvertRGBtoGray(matInput.getNativeObjAddr(), matResult.getNativeObjAddr());

Utils.matToBitmap(matResult,testbm);
iv1.setImageBitmap(testbm);

----------------Doing very Well--------------------------
TessOCR mTessOCR = new TessOCR();
String result = mTessOCR.getOCRResult(testbm);

System.out.println(result);
}

if (!dir.exists())
dir.mkdirs();
mTess.init(datapath, language);
}

public String getOCRResult(Bitmap bitmap) {

mTess.setImage(bitmap);
String result = mTess.getUTF8Text();

return result;
}

public void onDestroy() {
if (mTess != null)
mTess.end();
}
