Starts the device's native camera application to record a video or to take a photo.
Remarks:
  • iPhone/iPad Remark: Syntax 2, which uses a non-locking call, is recommended, especially from iOS 8.
  • Universal Windows 10 App CameraRunApp must be run in a thread.
  • In a WINDEV application, CameraCapture can be used to record a video or to take a photo with the camera of the device.
  • This function is equivalent to VideoStartApp.
Example
sPhoto is string
sPhoto = CameraRunApp(viPictureCapture)
IF sPhoto <> "" THEN
Info("Photo saved in the file " + sPhoto)
END
nRecordingType is int
 
// Let the user choose the type of capture
FI Dialog("Do you want to take a photo or record a video?", ["A photo", ...
"A video"], 1, 2, dlgIconQuestion) = 1 THEN
nRecordingType = viPictureCapture
ELSE
nRecordingType = viVideoCapture
END
 
// Starts the application
CameraRunApp(nRecordingType, CameraRunApp_Callback)
 
INTERNAL PROCEDURE CameraRunApp_Callback(sPath is string)
 
// If the return is an empty string vide (""), an error occurred
IF sPath ~= "" THEN
Error(ErrorInfo())
RETURN
END
 
// Message for end of recording
Info("The file was saved here: " + sPath)
END

Backup directories

AndroidAndroid Widget In Android applications, the photo or video is stored on the SD Card of the device and is automatically added to the album.
If photos must be used in your Android applications, we advise you to work with thumbnails and not with the initial photos taken by the device. To generate the thumbnails, use CameraGenerateMiniature.
iPhone/iPad In iPhone/iPad applications:
By default:
  • the photos are saved in the "Documents" directory of application.
  • the videos are saved in the "tmp" directory of application.
For the images, you can also:
  • store the binary content of the image in a database, via a Memo item.
  • add the photo to the photo album of the device with AlbumSave. In this case, the image can be re-used via AlbumPicker.
Universal Windows 10 App In the applications in Windows Store apps mode, the photos and the videos are saved in the "TempState" directory of the application.
