Can I integrate Microsoft Lens into my application?

If you look at Androidmanifest.xml file, you will see this XML:

If you read this file carefully you will see that this is impossible to interact this the other API's. Neither 'broadcast' no proper 'intent-filter' to interact this the other applications.

This is impossible nowadays.

Anyway, obviously, you can save to local storage and retrieve the data from SD card using your app.
