The DWG Viewer uses a native method GetLayoutNames() to get all available sheets of the drawing when documentActivated() is triggered. All layouts are passed to the method DocumentActivated() of the main activity and a corresponding button is created for each layout. The button is linked with a command expression that is executed when tapped. The command _SHEET_CONTROL handles the layout switch. The native method GetLayoutNames() manipulates the UI of the application and must be executed from the ui thread of the host application. A suitable method runOnUiThread() is provided by CFxARESInstance.instance().
