(Default value) One or more documents (image, video, pdf, ...) are shared. These documents are identified by their full path, specified as parameter (<Parameter 1> to <Parameter N>).
The document must be located in the shared memory of the device (for example: the SDCard) in order to be used by the external application selected for the share.
Only the images are supported.

If several character strings are specified as parameters (<Parameter 1> to <Parameter N>), they are concatenated and separated by carriage returns (CR).
Caution: The Facebook application does not allow you to share text automatically.

Special cases

To customize the title of popup for selecting the application, use NextTitle before StartShare.
If only one application lets you share the resource on the mobile, the popup is not displayed and the application starts directly.
Caution: This function is available in the Android emulator. This function is not available in the Android simulator.

Versions 25 and later

Application in the background: Specific case from Android 10

From Android 10, it is no longer possible to open a window when the application is in the background.

StartShare can open a window. If this function is used while the application is in the background, a fatal error will occur.

Tips:

It is possible to determine if the application is in the background using InBackgroundMode.
If an application needs to interact with the user while it is in the background, the solution is to display a notification (via the Notification type). The application will be brought back to the foreground when the notification is clicked, if the ActivateApplication property is set to True. You can also open a window from the procedure passed to the ActionClick property.
