Hi everybody,
does someone have an idea why clearing a data grid works fine in livecode but not if I start the App on my Android phone? Even when I reinstall the app the old data remains in it?! Would be great if someone could give a hint.

Hi Bastian,
It sounds like the Data Grid library might not be being included in your standalone. Can you select the "Select Inclusions" option on the General pane of the Standalone Application Settings and ensure that DataGrid is selected in the Inclusions pane and try again.
I hope that helps.
