The library's CaptureActivity has three defaults that put work on the
person holding the phone, so the scan now goes through our own subclass
instead:
- It decodes only the framing rectangle, inset 10% from every edge. A code
filling the viewfinder still decodes -- measured against the library's
own decoder rather than assumed -- but only by spending its quiet zone
on the crop, and anything further out is never looked at. The whole
preview is decoded now, so framing is not something to get right.
- It draws a red laser line and scatters dots wherever the detector finds
a candidate pattern. That is the library's house style, and it looks
like a fault. The preview is plain now.
- Its manifest entry pins the activity to landscape. The code being
scanned is usually on a monitor in front of someone holding the phone
upright, so ours follows the sensor.
Verified on the emulator: the scanner opens on a bare preview with no
laser, no dots and no status line.
