CameraActivity

CameraActivity is the main entry point to the Gini Capture SDK when using the Screen API.

It shows a camera preview with tap-to-focus functionality, a trigger button and an optional flash on/off button. The camera preview also shows document corner guides to which the user should align the document.

On tablets in landscape orientation the camera trigger button is shown on the right side of the screen for easier access.

If you enabled document import with setDocumentImportEnabledFileTypes then a button for importing documents is shown next to the trigger button. A hint popup is displayed the first time the Gini Capture SDK is used to inform the user about document importing.

For importing documents READ_EXTERNAL_STORAGE permission is required and if the permission is not granted the Gini Capture SDK will prompt the user to grant the permission. See Customizing the Camera Screen on how to override the message and button titles for the rationale and on permission denial alerts.

Start the CameraActivity with startActivityForResult to receive the extractions or a GiniCaptureError in case there was an error.

The following result codes need to be handled:

• RESULT_OK - image of a document was taken, reviewed and analyzed
• RESULT_CANCELED - image of document was not taken, user canceled the Gini Capture SDK
• RESULT_ERROR - an error occured

Result extra returned by the CameraActivity:

• EXTRA_OUT_EXTRACTIONS - set when result is RESULT_OK, contains a Bundle with the extraction labels as keys and as values.
• EXTRA_OUT_ERROR - set when result is RESULT_ERROR, contains a GiniCaptureError object detailing what went wrong

If the camera could not be opened due to missing permissions, the content of the Camera Screen is replaced with a no-camera icon, a short message and an optional button. The button is shown only on Android 6.0+ and tapping the button leads the user to the Application Details page in the Settings. If these are shown on Android 5.0 and earlier means that the camera permission was not declared in your manifest.

Customizing the look of the Camera Screen is done via overriding of app resources.

The following items are customizable:

• Document corner guides: via the color resource named gc_camera_preview_corners
