I have used OCR firebase form this course https://www.youtube.com/watch?v=_rO7A2ZHS3o

But I get this error when I click "Detect Text"

Caused by: java.lang.IllegalStateException: Default FirebaseApp is not initialized in this process com.atronteam.scandoctors. Make sure to call FirebaseApp.initializeApp(Context) first.

I have used FirebaseApp.initializeApp(this) in my onCreate Method but the error exists

Versions used: firebase-ml-vision: 16.0.0, android Studio: 3.4.1, min SDk version: 19

public class MainActivity extends AppCompatActivity {


    ImageView imageView;
    TextView textView;
    Bitmap bitmap;
    private static final int SELECT_PHOTO = 100;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        FirebaseApp.initializeApp(this);

        imageView = (ImageView) findViewById(R.id.imageView);
        textView = (TextView) findViewById(R.id.textView);


    }

    public void detect(View view) {
        if (bitmap == null) {
            Toast.makeText(getApplicationContext(), "Bitmap is null", Toast.LENGTH_SHORT).show();

        } else {
            FirebaseVisionImage firebaseVisionImage = FirebaseVisionImage.fromBitmap(bitmap);

            FirebaseVisionTextDetector firebaseVisionTextDetector = FirebaseVision.getInstance().getVisionTextDetector();

            firebaseVisionTextDetector.detectInImage(firebaseVisionImage)
                    .addOnSuccessListener(new OnSuccessListener<FirebaseVisionText>() {
                        @Override
                        public void onSuccess(FirebaseVisionText firebaseVisionText) {
                             process_text(firebaseVisionText);
                        }
                    });
        }
    }

    private void process_text(FirebaseVisionText firebaseVisionText) {
        List<FirebaseVisionText.Block> blocks = firebaseVisionText.getBlocks();
        if (blocks.size() == 0){
            Toast.makeText(getApplicationContext(),"No Text detected",Toast.LENGTH_SHORT).show();
        }
        else {
            for (FirebaseVisionText.Block block:firebaseVisionText.getBlocks()){
                String text = block.getText();
                textView.setText(text);
            }
        }
    }

    public void pick_image(View view) {
        Intent i = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.INTERNAL_CONTENT_URI);
        startActivityForResult(i, SELECT_PHOTO);
    }


    @Override
    protected void onActivityResult(int requestCode, int resultCode,Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        switch(requestCode) {
            case SELECT_PHOTO:
                if(resultCode == RESULT_OK){
                    Uri selectedImage = data.getData();
                    try {
                        bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(),selectedImage);
                        imageView.setImageBitmap(bitmap);
                    } catch (IOException e) {
                        e.printStackTrace();
                    }


                }
