Shows the form.

I am trying to create an application with 2 forms in Delphi XE6. Depending on a ParamStr setting Form2 may or may not be shown before Form1.

In normal Delphi, once a form is created, I can hide and show it multiple times.

I'm facing a problem with Delphi Alexandria.

Use ShowModal to show a form as a modal form. A modal form is one where the application can't continue to run until the form is closed. Thus, ShowModal does not return until the form closes. When the form closes, it returns the value of the ModalResult property.

I am having trouble showing a secondary form from the main form OnShow event for (only) the Android platform.

To close a modal form, set its ModalResult property to a nonzero value.

Note: If the form contains buttons with a ModalResult property set to a value other than mrNone, the form automatically closes when the user clicks one of those buttons and returns the ModalResult value as the return value of ShowModal.

You can check the return value against common return values using the global IsAbortResult, IsAnAllResult, IsNegativeResult, or IsPositiveResult functions.
