It is not possible to find out whether an application was selected by the user to perform the share.
False if no application allowing to share the resources is found. To find out the error details, use ErrorInfo.

(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.

Caution: The Facebook application does not allow you to share text automatically.

Remarks

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: Android 10 specific case

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). When the notification is clicked on, the application will be brought back to the foreground if ..ActivateApplication is set to True. It is also possible to open a window from the procedure passed to ..ActionClick.

See Android 10: Behavior of applications in the background for more details.
