Hello, I've implemented Google authentication on my app using Firebase and the Kastri library. I've done all the configurations as per the GoogleSignin example project. On iOS, both in demo and on the Store, it works perfectly. On Android, it works correctly if I compile in development, but if I compile for the Store and upload it, the authentication returns a code 10. I've checked all the SHA-1 fingerprints for KeyStore.debug, development KeyStore, and the app in the Google Store at https://console.firebase.google.com/. I'm using the Client ID generated for the Web App (as per the example instructions) and not the Android ones (which just don't work). Do you have any suggestions on what it could be? Thanks Massimiliano

I am having a problem using the PDFControl on Android device. Have followed the example code for using the PDFControl in demo provided by Kastri but all I get is the PDF displayed in a narrow vertical area (small, about 10mm wide) up the middle of the screen. In the onCreate event I have placed if TOSVersion.Platform = TOSVersion.TPlatform.pfAndroid then begin FPDFControl := TPDFControl.Create(Self); FPDFControl.Align := TAlignLayout.Client; FPDFControl.Parent := TabItem17; end; The PDF needs to be displayed in TabItem17 of a TabControl. TabItem17 has nothing on it except for a TLayout at bottom of screen with a button to enable return to another TabItem. Following is the code used to load and display the PDF procedure TMainForm.Display_PDF(const sFile : string); begin {$IF DEFINED(ANDROID)} if FPDFControl <> nil then FPDFControl.LoadPDF(sFile); TabControl1.SetActiveTabWithTransition(TabItem17,TTabTransition.Slide, TTabTransitionDirection.Normal); {$ENDIF} {$ifdef win32} PDFBrowser.Navigate('file://' + sFile); TabControl1.SetActiveTabWithTransition(TabItem13,TTabTransition.Slide, TTabTransitionDirection.Normal); {$ENDIF} end; Can anybody please help with what I need to do to display the PDF properly. Thanks in advance. Bill Zwirs
