Syntax

<Result> = ShellExecute(<File name> [, <Verb>])

<Result>: Boolean

True if the document was opened,
False otherwise.
This parameter is not available. This function returns no result.
Returns False if the application is run with a Java virtual machine (JRE) earlier than version 1.6.

<File name>: Character string (with quotes)

Name and full (or relative) path of document to open. A UNC path can be used.
If space characters are found in the name or path of the document to open, the quotes found around this parameter must be tripled.
This parameter can also correspond to a Windows shortcut.
No relative path or UNC path can be used.
Versions 16 and later
This parameter can correspond to a full path, to a relative path or to a URI.
For example:
"/sdcard/photo.png"

"http://www.windev.com": starts the Web browser on the specified page.
"geo:1.44951,43.604363": starts Google Maps or equivalent.
"mailto:pcsoft@pcsoft.fr" starts the application for sending emails.
"sms:0612345678": starts the application for sending SMSs.
The files found in the application directory (or in one of its sub-directories) are not accessible by most of the external applications. We recommend that you use ShellExecute with files found on the external memory of the device (for example: sdcard) because they are accessible from all the applications.

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.

ShellExecute 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.
