Simple example of OCRReader in Android.

Hi Friends, Maybe you all heard/used text scanning using camera feature or extracting text from Image. But this sample made it very easy for you. You can made it in very simple line of code.

You can download the source code from OCRSample and import the library as a module into your project.

Example usage : MainActivity.java

public class MainActivity extends AppCompatActivity {

    private TextView textView;
    private final int CAMERA_SCAN_TEXT = 0;
    private final int LOAD_IMAGE_RESULTS = 1;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        textView = findViewById(R.id.textView);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.menu_main, menu);
        return super.onCreateOptionsMenu(menu);
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()) {
            case R.id.actionCamera:
                //Scan text from camera.
                OCRCapture.Builder(this)
                        .setUseFlash(true)
                        .setAutoFocus(true)
                        .buildWithRequestCode(CAMERA_SCAN_TEXT);
                break;
            case R.id.actionPhoto:
                Intent intentGallery = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
                startActivityForResult(intentGallery, LOAD_IMAGE_RESULTS);
                break;
        }
        return super.onOptionsItemSelected(item);
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (data != null) {
            if (requestCode == CAMERA_SCAN_TEXT) {
                if (resultCode == CommonStatusCodes.SUCCESS) {
                    textView.setText(data.getStringExtra(TextBlockObject));
                }
            } else if (requestCode == LOAD_IMAGE_RESULTS) {
                Uri pickedImage = data.getData();
                try {
                    //Extract text from image.
                    String text = OCRCapture.Builder(this).getTextFromUri(pickedImage);
                    //You can also use getTextFromBitmap(Bitmap bitmap) or getTextFromImage(String imagePath) buplic APIs from ibrary. 
                    textView.setText(text);
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }
    }
}
