    I'll be having an iPhone with iOS 18.3.
    Would that be a problem deploying from Delphi 12.1 to this device.
    I assume I'll upgrade my MacOS to 15.3 and use XCode 16.1
    (Minimum MacOS to run XCode 16.1 is Sonoma 14.5, from what I checked)

     

    I won't use any new features in iOS 18.3 - just basic features already found in

    lower iOS sdks such as iOS SDK 14 or 15.

    Will this cause any problem?

    I'm asking because if I buy the iPhone (18.3) and then is stuck with it as I will not be upgrading to 12.2 for a while.

    Thanks for any advice!

    Thanks for the reply, Dave.

     

    sorry, I've been too overwhelmed to look into the log msg as it seems quite a lot of setup.

     

    Anyway, I ran the same code in Android 15 and it worked fine!

     

    It's quite disappointing though that it worked in 15 and not 9.  How would I know if my app

    will work on Android 10-14?  Surely it's not practical to test all.

    That's "official" support. Theoretically, Delphi 12 can be used to create apps that run on Android 5 or later.

    Does the camera not appear at all, or is it once you've taken a photo? If the latter, you should show your code for TakePhotoDidFinishTaking. A complete test case would be even better

    Just because there's a lot of messages, it does not mean it is not useful. Use filtering to see only relevant messages. This link might help.

    Thanks for the reply.  The camera did not show at all.  The app crashed as in "closed without error message".

     

    procedure TForm2.DidCancelTaking(const Sender: TObject; const M: TMessage);

        // do cancellation stuff
      end;

    begin
      //if Assigned(OnDidCancelTaking) then
      //Memo1.lines.insert(0,'cancel taking photo');
    end;

    oh, thanks for the response!  I didn't know that Android 9 is not supported.

    Delphi 12 Athens is here! – Delphi Worlds
    -> it says Android 8.1  so I'm a little confused.

     

    There's no error. click the button to take photo and the app closes.  As for the adb log,

    it is way too many, so I didn't think it would be useful.

     

    I'll try to get a newer Android phone.  Meanwhile, if anyone has similar experiences, please let me know possible solutions.

     

    thank you!

    I used this for Delphi 11.x with Android 9. No issue.  Now the same code in Delphi 12.1 crashes

    after I "allow camera" in Android phone.  Permissions [x] Camera.  I even enabled "Secured File Sharing" just to be safe.
    Any advice?  A similar service for Select Photos From Folder (IFMXTakenImageService) does not crash.

    Any advice on this?

    var
      Params: TParamsPhotoQuery;
    begin

      if TPlatformServices.Current.SupportsPlatformService(IFMXCameraService,
        FCameraService) then
      begin
        Params.Editable := False;
        Params.NeedSaveToAlbum := False;
        Params.RequiredResolution := TSize.Create(640,640);
        Params.OnDidFinishTaking := TakePhotoDidFinishTaking;
        Params.OnDidCancelTaking := DoCancelTaking;
        FCameraService.TakePhoto(button1, Params);
      end else
      begin


      end;

    I ran my Android 64-bit app.  The splash screen hanged without giving any error.

     

    Running a blank app is ok.  What is the best way to find out what happened during the loading?

    I tried running app in DEBUG mode, but each time I pressed F7 or F8, the deployment process will re-start all

    over again.  It seems the app does not even hit the first line of the .DPR project file.

     

    I know how to start logcat but there are so much messages coming in.

    Any other way to debug Android 64 apps?

    Do I really have to comment out as much code as possible, and slowly add them back in?

     

    Thanks for any ideas.

    Hi Vincent!

    thanks for the reply.

    If you want full pascal 3d engine, CGE is still a good candidate, and can do realistic images.

    I didn't know it can do realistic images as the examples on youtube show a little "cartoon-like" renderings.

    Afterwarp is very good too, more industrial goal, and it is distribute as a lib, and is written in c++. It is distribute with a clean wrapper and an high level pascal objects lib available for delphi and fpc. Wrapper is available since 3.0 for c# too. 

    ok, I'll check this out.

     

    What I'm trying to do is go close to a Blender 3D software rendering... meaning if I put in textures & lightings, it can give me an almost photo-realistic rendering.

     

    There was one suggestion of using Firemonkey 3D. I have tried it using the 3D forms etc.  However, I read that the "perspective" generated in Firemonkey is not correct

    (similar to old-generation 3D rendering engines). Not sure whether this is true.

     

    I'll check out the links you gave. Thanks!

     

    Lastly, do let me know if I can achieve Blender-like 3D renderings with textures and lightings... eg. I would want water and glass to look natural too.

     

    thanks

    Most of the 3D render engines seem to be C++.  It doesn't seem to be trivial to translate the C++ to headers that can be used by Delphi.

     

    Are there any existing 3D libraries that work with Delphi?  When I mean 3D, I don't mean Castle game engine type (not realistic enough).

     

    thanks for any pointers.

    Yes, you can safely ignore them ( until Google decides to enforce this probably in the future ).

     

    I considered that too, but I'm afraid these warning will be hard to remove, because they require certain Android tools, like ProGuard.
    Not sure if this will be ever included in the Delphi process.

    One idea, at least for the first warning, was to add a neutral or empty "manifest.txt" file.
    This might work technically, but on the other hand, the Google Review might see this as an attempt to circumvent or infringe their PlayStore policies,
    which might put you in bigger troubles.

    My hope is, that Embarcadero put this onto their roadmap.

     

     

     

    Thanks for the tip.

     

    I found this link  [Android] How to upload native deubg symbols to playstore? · fastlane/fastlane · Discussion #21090 · GitHub

    for the debug symbols.

     

    if anyone figured out how to do it for Delphi, do update here 🙂

    ok thanks a lot, Dave!  by the way, "targetSdkVersion" can only be inserted by Delphi?  can we define this anywhere? i looked through Project Options but there is nothing to override.

    so I assumed changing the XML hard-coded is the only way?

    After submission, no errors, but there are 2 warnings.... should I ignore them?

    Warning

    There is no deobfuscation file associated with this App Bundle. If you use obfuscated code (R8/proguard), uploading a deobfuscation file will make crashes and ANRs easier to analyze and debug. Using R8/proguard can help reduce app size. Learn More

     

    -> I suspect this is inevitable for Delphi app ?

     
    Warning

    This App Bundle contains native code, and you've not uploaded debug symbols. We recommend you upload a symbol file to make your crashes and ANRs easier to analyze and debug. Learn More

     

    -> is there an easy way to include a debug symbols file if I'm compiling a Release version (not a debug version)?

    This says otherwise: https://blogs.embarcadero.com/delphi-supports-android-api-33-via-yukon-beta/

     

    Please see also: 

     

    shouldn't https://docwiki.embarcadero.com/PlatformStatus/en/Main_Page be the latest update of all? while the Yukon article was posted while 12 was in beta.

     

    anyway, I tried configuring apk 33  just to see if a basic app will work. surprisingly it compiled, BUT when I uploaded to Google portal, it complained I was targeting

    sdk 32 instead of 33! I don't even have sdk 32 installed!

     

    My AndroidManifest.template.xml says:

        <uses-sdk android:minSdkVersion="23" android:targetSdkVersion="33" />

     

    any solutions to this? where else could I be specifying 32 wrongly?

    It's clearly stated that Delphi 11.3 supports Android 13 (sdk 33.0).

     

    I have tried for hours to configure SDK 33 into Delphi 11.3 with no success.

     

    I used Android Studio to download SDK 33.0 and latest NDK 26.

     

    Does anyone have a working 11.3 + Android SDK 33? and will care to share their installation tips?

     

    thanks

    Using Delphi 11 patch 2

    (btw,

     

    I used the custom Android installer documented in

    https://delphiworlds.com/2020/09/manual-android-sdk-ndk-install-delphi/

    (The default SDK Manager installed with Delphi does not show sdk 30.03 so was forced to use this)

    --> I'm just wondering why I can only use this tool and not the standard SDK Manager from Delphi.


    installed it to c:\androidsdk\sdk

    (where there was previously a 29.0)


    and the ndk is in c:\androidsdk\ndk  

    (Android NDK 21e that worked with 29.0 previously, and since it also has a 30.0 support folder)


    Unlike Android SDK 29.02 which was detected by Delphi 10.4.1 IDE
    In Delphi 11, Tools-Options, SDK Manager, i chose "Add" new SDK
    In the dialog, I select all the appropriate directories,
    but in the "SDK API Level" dropdown, it says "Cannot locate SDK API Level"


    If I browse to an old SDK folder, it can detect for eg, android25 or android 26.


    so I know the Delphi 11 Tools-Options SDK can detect android sdks.


    Anyway, I ignored the warning "Cannot locate SDK API Level in this path, please, check your selection. Do you want to save your changes anyway?"

    since I have no choice.


    1) How can I get Delphi 11 Tools-Options-SDK to properly recognise Android 30, given that 29.0 was recongised easily.

     

    2) Is there a preferred version of NDK that I should use with Android SDK 30.0?

     

    3) I used Kastri biometric example to run Delphi 11 the BiometricDemo.dpr instead of BiometricDemoD11.dpr (BiometricDemoD11.dpr gave too many error messages when compiling).

    I added 3,628 dw-biometric-2.0.0.jar  to the Android libraries

    The example that came out hang at the splash screen... and got stuck there.

     

    Any advice?
