Field Detail¶

ACTION_IMAGE_CAPTURE¶

static final String ACTION_IMAGE_CAPTURE

Intent action that can be sent to have the Iristick camera application capture an image and return it.

The caller may pass an extra EXTRA_OUTPUT to control where this image will be written. If the EXTRA_OUTPUT is not present, then a small sized image is returned as a Bitmap object in the extra field. This is useful for applications that only need a small image. If the EXTRA_OUTPUT is present, then the full-sized image will be written to the Uri value of EXTRA_OUTPUT. This Uri can also be supplied through setClipData(ClipData).

See Also:: EXTRA_OUTPUT

ACTION_VIDEO_CAPTURE¶

static final String ACTION_VIDEO_CAPTURE

Intent action that can be sent to have the camera application capture a video and return it.

The caller may pass in an extra EXTRA_VIDEO_QUALITY to control the video quality.

The caller may pass in an extra EXTRA_OUTPUT to control where the video is written. If EXTRA_OUTPUT is not present the video will be written to the standard location for videos, and the Uri of that location will be returned in the data field of the Uri. This uri can also be supplied through setClipData(ClipData).

See Also:: EXTRA_OUTPUT, EXTRA_VIDEO_QUALITY, EXTRA_SIZE_LIMIT, EXTRA_DURATION_LIMIT

ACTION_SCAN_BARCODE¶

static final String ACTION_SCAN_BARCODE

Intent action that can be sent to capture a barcode and return the decoded data.

The caller may pass in the following extras to control the decoding process:

EXTRA_BARCODE_SCAN_FORMATS

The result will contain extras EXTRA_BARCODE_RESULT and EXTRA_BARCODE_FORMAT.

See Also:: EXTRA_BARCODE_SCAN_FORMATS, EXTRA_BARCODE_RESULT, EXTRA_BARCODE_FORMAT

ACTION_VIEW¶

static final String ACTION_VIEW

Intent action that can be sent to show a piece of data to the user.

The caller must pass the URI to the data to Intent.setData(android.net.Uri). The mime type and/or path extension of the URI determines how the data is shown to the user. Supported mime types/extensions are:

Extension	MIME type
.bmp	image/bmp
.bmp	image/x-windows-bmp
.gif	image/gif
.jpeg	image/jpeg
.jpg	image/jpeg
.jpeg	image/pjpeg
.jpg	image/pjpeg
.png	image/png
.webp	image/webp

The caller may pass in an extra EXIT_ON_ZOOM_OUT to control whether the intent should be closed and control returned to the caller when the user tries to zoom out while the view is already completely zoomed out. By default, the user must explicitely close the viewer by pressing on the back button, swiping down on the touchpad or saying "go backwards".

See Also:: EXTRA_EXIT_ON_ZOOM_OUT

EXTRA_OUTPUT¶

static final String EXTRA_OUTPUT

The name of the Intent-extra used to indicate a content resolver Uri to be used to store the requested image or video.

EXTRA_VIDEO_QUALITY¶

static final String EXTRA_VIDEO_QUALITY

The name of the Intent-extra used to control the quality of a recorded video. This is an integer property. Currently value 0 means low quality, suitable for MMS messages, and value 1 means high quality. In the future other quality levels may be added.

EXTRA_SIZE_LIMIT¶

@Deprecated
static final String EXTRA_SIZE_LIMIT

Deprecated. There is no guarantee that the final size of the recorded video will not be greater than this limit. Therefore, use of this extra feature is discouraged.

Specify the maximum allowed size in bytes for video capture.

EXTRA_DURATION_LIMIT¶

static final String EXTRA_DURATION_LIMIT

Specify the maximum allowed recording duration in seconds.

EXTRA_BARCODE_SCAN_FORMATS¶

static final String EXTRA_BARCODE_SCAN_FORMATS

A String extra with a comma-separated list of barcode formats to detect.

See CaptureRequest.POSTPROCESS_BARCODE_FORMATS for a list of possible values. For example, to scan only for EAN-8, EAN-13 and QR-codes, set this extra to "EAN_8,EAN_13,QR_CODE".

Unknown formats will be silently ignored, as well as formats that are unavailable on the connected headset. If this extra is not provided, a subset of the most common formats is selected.

See Also:: CaptureRequest.POSTPROCESS_BARCODE_FORMATS

EXTRA_BARCODE_RESULT¶

static final String EXTRA_BARCODE_RESULT

A String extra containing the decoded barcode.

EXTRA_BARCODE_FORMAT¶

static final String EXTRA_BARCODE_FORMAT

A String extra containing the decoded barcode format.

EXTRA_EXIT_ON_ZOOM_OUT¶

static final String EXTRA_EXIT_ON_ZOOM_OUT

A boolean extra indicating whether the intent should be closed when the user asks to zoom out while the view is already completely zoomed out. This only concerns the "zoom out" voice command; zooming out with the touchpad never closes the intent.

RESULT_OK¶

static final int RESULT_OK

Activity result code: operation succeeded.

RESULT_CANCELLED¶

static final int RESULT_CANCELLED

Activity result code: operation canceled.

RESULT_UNKNOWN_ERROR¶

static final int RESULT_UNKNOWN_ERROR

Activity result code: an unknown error has occurred.
