Check if android OCR is downloaded or not

Question

I have used OCR, from google vision api, where I used the app to detect text from screen using text recognizer API. But, as the document says, it needs to download the necessary files from the internet and it says that it downloads when the app is downloaded from play store

 <meta-data
        android:name="com.google.android.gms.vision.DEPENDENCIES"
        android:value="ocr" />

Is there any way how I can check if the necessary files are downloaded or not? If not, I want to start the download, once the user gets connected to wifi.
