In line 3 there is if that check if text recognizer is operational or not and when I run program on my asus me371 mg tablet it will never go in else. It means text recognizer is never operational, what should I do?
TextRecognizer textRecognizer=new TextRecognizer.Builder(getApplicationContext()).build();
if (!textRecognizer.isOperational()) {
Log.w("MainActivity", "Detector dependencies are not yet available");
} else {
cameraSource = new CameraSource.Builder(getApplicationContext(), textRecognizer)
.setFacing(CameraSource.CAMERA_FACING_BACK)
.setRequestedPreviewSize(600, 400)
.setRequestedFps(2.0f)
.setAutoFocusEnabled(true)
.build();
cameraView.getHolder().addCallback(new SurfaceHolder.Callback() {
@Override
public void surfaceCreated(SurfaceHolder holder) {
try {
if (ActivityCompat.checkSelfPermission(getApplicationContext(), android.Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(MainActivity.this,new String[]{android.Manifest.permission.CAMERA},ReqiestCameraPermissionID);
return;
}
cameraSource.start(cameraView.getHolder());
}catch (IOException e){e.printStackTrace();}
}
@Override
public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) {
}
@Override
public void surfaceDestroyed(SurfaceHolder holder) {
cameraSource.stop();
}
});
textRecognizer.setProcessor(new Detector.Processor<TextBlock>() {
@Override
public void release() {
}
@Override
public void receiveDetections(Detector.Detections<TextBlock> detections) {
final SparseArray<TextBlock> items =detections.getDetectedItems();
if (items.size()!=0){
textView.post(new Runnable() {
@Override
public void run() {
StringBuilder stringBuilder =new StringBuilder();
for (int i =0 ; i<items.size();++i){
TextBlock item=items.valueAt(i);
stringBuilder.append(item.getValue());
stringBuilder.append("\n");
}
textView.setText(stringBuilder.toString());
}
});
}
}
});
}
