Crash on android with scanDoc 1

[dylanvdmerwe]

Crash occurs with the following code:

    scan.scanDoc(1, (imgUri) => {
      console.log(imgUri);
    }, (err) => {
      console.error(err);
    });

The aim is to open the camera to scan a document. Tested on Android 8.1 (Pixel 2 XL).

Note that scan.scanDoc(0 works as expected.
