AndroidAndroid Widget This parameter can correspond to a full path, to a relative path or to a URI.
For example:
  • "/sdcard/photo.png"
  • "/sdcard/video.3gp".
  • "": starts the Web browser on the specified page.
  • "geo:1.44951,43.604363": starts Google Maps or equivalent.
  • "" starts the application for sending emails.
  • "sms:0612345678": starts the application for sending SMSs.

It is recommended to use ShellExecute with files located on the external memory of the device (e.g.: sdcard) because they are accessible from all the applications.
Universal Windows 10 App Only the files found in the "appdata" directory can be handled. No Internet URL can be specified.
<Verb>: Optional character string
Verb that must be used to start the document. The verbs are defined for each application, to indicate the actions that can be performed. The most common verbs are open or print. If this parameter is not specified, the verb used will be the default verb for the type of document.

Running an APK file setup

From Android 8, to run the setup of an APK file with ShellExecute, it is necessary to modify the permissions required by the application.
Required permission: REQUEST_INSTALL_PACKAGES.
This permission is used to install packages.
For more details (especially for previous versions of WINDEV Mobile), see FAQ 16927: What to do on Android 8 if the setup of an APK file with ShellExecute is no longer allowed?.

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