try {
    TextRecognizer txtRecognizer = new TextRecognizer.Builder(getApplicationContext()).build();
    if (!txtRecognizer.isOperational()) {
    } else {
        Frame frame = new Frame.Builder().setBitmap(bitmap).build();
        SparseArray items = txtRecognizer.detect(frame);
        StringBuilder strBuilder = new StringBuilder();
        for (int i = 0; i < items.size(); i++) {
            TextBlock item = (TextBlock) items.valueAt(i);
            strBuilder.append(item.getValue());
        }
        Log.d("My Text : ", strBuilder.toString() + " okok");
    }
} catch (Exception e) {
    e.printStackTrace();
