  - ACTION
```
public static final java.lang.String ACTION
```
    Send this intent to open the Barcodes app in scanning mode, find a barcode, and return the results.

  - MODE
```
public static final java.lang.String MODE
```
    By default, sending this will decode all barcodes that we understand. However it may be useful to limit scanning to certain formats. Use Intent.putExtra(String, String) with one of the values below. Setting this is effectively shorthand for setting explicit formats with FORMATS. It is overridden by that setting.
