I have a number of FMX based programs that do not draw there forms correctly when built for the Android platform under Tokyo. The programs work fine on Berlin update 1 and 2. The same programs complied for Win64 or Win32 under Tokyo seam to work fine.
I have only had time to test the android apps on a Samsung S5 (6.01), S6 (6.01) and a Samsung TabS (6.01).
Each of the programs has 8 to 10 forms. When a form is shown it does not always display but the controls on the form are active.
The programs use a local SQLite database using FireDac and live bindings to display data. All of the forms which use live bindings from the FireDac database to one or more ListViews in a MultiView will not draw at all. While you can not see the form all of the forms controls are active.
I have one application form that uses live bindings but has no MultiView. The form has a hidden panel (visible=false). When the panel is made visible the form does not update to show the panel but the controls on the panel are active.
In the IDE I can not show the contents of a MultiView when the "Master" form layout is selected. If I select the "Windows" or "Android" layouts the show command displays the MultiView.
