Installing Delphi 12.2 Inline patch 1 - no android support .. [Resolved]
JohnLM posted a topic in Cross-platform
This is so frustrating, every time I reinstall Delphi, I have to do something in order to get the Android functions to work for deployment. I have those familiar 3 triangles, and I just can't remember what I did the last time to resolve it, and I can't find it here where I i know I posted it. Does anyone know what I need to do to clear those yellow triangles in SDK Manager? -

Hi, does anyone ever tried to install Android APK in Fusion Hybrid Tablets? https://www.touchdynamic.com/products/mobile-pos-tablets/fusion-tablet-solution/ This is their manual & specs: https://www.touchdynamic.com/wp-content/uploads/2024/09/TD_FusionHybrid_SpecSheet5.pdf I'm not sure if it's something with their processor architecture (Intel® Elkhart Lake Celeron® J6412 up to 2.6 Ghz System), as I'm unable to install any APK built and deployed in Delphi, neither MSBuild, anything.... I just get a message from the OS stating "App not installed as app isn't compatible with your tablet ". I've also tried to change dproj to support other architectures but without results. <PropertyGroup Condition="'$(Base)'=='Android'"> ... <AndroidSupportedAbis>x86;x86_64;armeabi-v7a;arm64-v8a</AndroidSupportedAbis> ... </PropertyGroup> Other thing I did is changing where lib is deployed but likewise, no results. Not a clue what's going on.

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 developing an android application on Delphi 12. My application connects to a DataSnap server. Some times, but not every time, my application throws this exception. Once when the application starts, the second time when a new form is opened and sometimes everything works without error I suppose everything crashes on line 312 in this module Those any one know the reason of this?

Have recompiled an app for Android with Delphi 11.3 and now get the following error when entering numbers into a dbdatagrid (Firepower) and tmsfnc edit control (in both cases have keyboard set to numberpad): Eval Error in: java.lang.indexoutofboundsexception setspan(3...3) ends beyond length 1. The error only occurs on Android tablet - not on Windows version. Have never seen this error before under previous versions of Delphi. Can someone please shed some light on this problem and point me in the right direction to fix it. Bill

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

Hello, I am working with Rad Studio and I need to make an application in Delphi for the phone that connects via USB to an Esp32 and sends and receives data. I didn't find anything available for delphi, so I chose to download a java library that handles it(https://github.com/mik3y/usb-serial-for-android), downloaded the .jar and converted it to .pas with java2op, but now I can't find a way to use the methods correctly and have the devices detected. by usb. Could you see this system, tell me how I could call the classes and methods in the interface or do you have some direct form of Delphi that allows me to make the connections with the USBs or at least see the connected devices usb-serial-for-android-3.8.0.jar JavaInterfaces.pas

Delphi 11.2 I use Winsoft Pdfium for FireMonkey to create a PDF that includes a graphic (png saved to a SQLite table field). The graphic is inserted into the pdf document (as the document is being created) with the following code: Sig := tMemoryStream.Create; try MarafillerDM.EMUInvQrySIGNATURE.SaveToStream(Sig); var aBitMap := FMX.Graphics.TBitmap.Create; try aBitMap.LoadFromStream(Sig); MarafillerDM.FPdf1.AddPicture(aBitMap,18,135,230,80); finally aBitMap.Free; end; finally Sig.Free; end; Up until a couple of weeks ago this worked for both Windows and Android without any problems but now I get an 'Unsupported Pixal Format' error from the Winsoft AddPicture procedure - but only on Android devices (Samsung Tab 6 Lite). On Windows it still works fine. Haven't changed anything in my Delphi environment (updates etc) between it working and not working. Has anyone else experienced this. Would appreciate any help with this issue. Bill Zwirs

I created a Datasnap server application that connects to the MSSQL database via the TFDConnection object, and then executes a specific SQL query via the TFDQuery object, the results of which are further forwarded via the TDataSnapProvider object. This is screenshot of that application I created a simple client application that opens this query and displays the results in a ListBox. This is the code : When I run application on Windows I get a correct result with Serbian letters as you can see in the image below But when U start the same application on Android, I have a problem with display of Serbian letters. What is the problem? Thanks

I have a reconnection problem in an android application,using Indy TidTcpClient and TIdThreadComponent. I've tried both the Delphi bundled and the latest Indy version. At the beginning, the program goes through the IP addresses of the available devices. Read and write routines work without problems, but when you try to change the IP address, almost without exception the program freezes. Sometimes it takes a few seconds, sometimes a few minutes before the program responds and about every ten times the program stops responding completely. In Windows, changing the IP address works reasonably well, but sometimes it also freezes. Receiving works...: try StartChar := TCPSocket.IOHandler.ReadChar; if StartChar = '%' then begin Data := TCPSocket.IOHandler.ReadLn('&'); Payload := Data; TCPSocket.IOHandler.ReadBytes(ChecksumBytes, 4); ReceivedChecksum := BytesToString(ChecksumBytes); CalculatedChecksum := CRC16(Payload); if ReceivedChecksum = CalculatedChecksum then begin TThread.Queue(nil, procedure var i: Integer; begin HandleData; end); end else begin TThread.Queue(nil, procedure begin HandleChecksumError; end); end; end; except on E: Exception do begin TThread.Queue(nil, procedure begin HandleException; end); ReceiveThread.Terminate; end; ...but changing IP fails: procedure IpSelectF.IPBtnClick(Sender: TObject); Var Btn: TButton; NewIp: string; begin if Sender is TButton then begin Btn := TButton(Sender); if AvailableIP[Btn.Tag] then begin TTask.Run( procedure begin try if Assigned(MainF.ReceiveThread) and MainF.ReceiveThread.Active then begin MainF.ReceiveThread.Stop; MainF.ReceiveThread.WaitFor; end; if MainF.TCPSocket.Connected then MainF.TCPSocket.Disconnect; NewIp := '192.168.1.' + IntToStr(Btn.Tag); MainF.TCPSocket.Host := NewIp; try MainF.TCPSocket.ConnectTimeout := 3000; MainF.TCPSocket.Connect; if MainF.TCPSocket.Connected then begin TThread.Queue(nil, procedure begin MainF.ReceiveThread.Start; ShowAlertDialog('Connected to ' + NewIp); end ); end else begin TThread.Queue(nil, procedure begin ShowAlertDialog('Connection to ' + NewIp + ' failed.'); end ); end; except on E: Exception do begin TThread.Queue(nil, procedure begin ShowAlertDialog('Failed to connect to ' + NewIp + ': ' + E.Message); end ); end; end; except on E: Exception do begin TThread.Queue(nil, procedure begin ShowAlertDialog('Error during IP switch: ' + E.Message); end ); end; end; end ); end; end;

Specs: Delphi XE7, FMX, Win7, Galaxy s10+ phone Android 12. I've have compile and deployed many apps over to my Android 12 device, galaxy s10+ phone. Earlier this year (2024) I stopped working on those projects I used to compile in this setup/specs (listed above). Today, I am trying to deploy an app and now I can not because of the 'Unsafe app blocked message'. I recall seeing something similar in late Dec/2023 on this phone, but there was a button to allow or not, and now I don't see that on this message screen given on my phone. How can I resolve this?

Trying to load a website with TWebBrowser, the site have self signed certificates which will be flagged as not safe. I am ending up with a blank page. TWebBrowser.OnDidFailLoadWithError never trigger. The blank page occur on IOS and Android. On Windows there is a warning page, (NET::ERR_CERT_AUTHORITY_INVALID) What is the best way of catching the certificate errors or even better ignore them so the page can load? The application is only talking with its own web servers so the security isn't a problem here.

Good day! Tell me the mechanisms that allow you to compress video files in Android and iOS applications Short mp4 files created by the camera take up a lot of space and do not load into my applications. Large files sent via messengers are load successfully. I understand that messenger servers use ffmpeg compression. Is it possible to apply ffmpeg compression in android and ios applications? There are no problems under Windows! Or are there other methods? To solve my problems, only compressing mp4 files is enough!

android Delphi Android Intent while App is active creates black screen
DominikR posted a topic in FMX
Hey, i updated RAD Studio to version 12 last week. Now i wanted to update my app to work with the new android play store requirements. While testing my features i found out, that my app keeps on hanging on a black screen when i try to import a text file with a file explorer. When i manually close the app, and choose a text file and open it with my app it is working fine, but when i open the app, and then go back to my file explorer select the text file to open it again it hangs in a black screen. I tried it also with a completely new project and had the same result. I am using a Pixel 8 with Android 14. I added this intent filter to my AndroidManifest.template.xml in the activity section: <activity android:name="com.embarcadero.firemonkey.FMXNativeActivity" android:exported="true" android:label="%activityLabel%" android:configChanges="orientation|keyboard|keyboardHidden|screenSize|screenLayout|uiMode" android:launchMode="singleTask"> ... <intent-filter> <action android:name="android.intent.action.VIEW" /> <category android:name="android.intent.category.DEFAULT" /> <category android:name="android.intent.category.BROWSABLE" /> <data android:mimeType="text/plain" /> </intent-filter> </activity> And handle it like that: var currentIntent := MainActivity.getIntent(); HandleIntentAction(currentIntent); The handling works like a charm. When starting the app in debugging nothing happens, also logcat is showing noting in regards of my app. I also added some ShowMessages to the FormCreate functions, but also nothing. I added two logcat logs as an attachment to this post. In my opinion there is nothing wrong in the not working log. In addition to the hanging, is there a possibility to open a view directly with an intent because when i try to do a form.show it wont show up, but i haven't followed up on this issue because i wanted to resolve the black screen first. Thank you in advance! Kind regards, Dominik not_working.log working.log
