| 
 
The launch() method requests that the device open the default camera application. The captured image or video is available in the MediaEvent object dispatched for the complete event. Since the default camera application can save the image or video in a variety of formats, there is no guarantee that returned media object can be loaded and displayed by the AIR runtime. |
| 
 
On some platforms, the media object returned by the camera is accessible as a file-based media promise. On others, the media promise is not file-based and the file and relativePath properties of the MediaPromise object are null. Do not use these properties in code that is used on more than one platform. |
| 
 
On Android, the default camera application does not open if the external storage card is not available (such as when the user has mounted the card as a USB mass storage device). In addition, the AIR application that launches the camera loses focus. If the device runs low on resources, the AIR application can be terminated by the operating system before the media capture is complete. |
| 
 
On some platforms, the media object is automatically stored in the device media library. On platforms on which images and video are not automatically stored by the default camera application, you can use the CameraRoll addBitmapData() function to store the media object."/> |
