I have an app that uses SqLite on Android and iOS in encrypted mode. I'm migrating the app from Delphi 10.4 to Delphi 12.2. I get a link error I've never seen before : [DCC Error] E2597 C:\Users\Public\Documents\Embarcadero\Studio\23.0\CatalogRepository\AndroidNDK-21-23.0.53982.0329\android-ndk-r21\toolchains\arm-linux-androideabi-4.9\prebuilt\windows-x86_64\bin\arm-linux-androideabi-ld.exe: error: C:\\Program Files (x86)\\Embarcadero\\Studio\\23.0\\lib\\Android\\Release/libsqlite_fde.a(sqlite3_fde.o): multiple definition of 'sqlite3_aggregate_context' The file libsqlite_fde.a exists in all delphi directories "lib/android/debug" and "lib/android64/debug". I attach all error strings. If anyone has an idea on how to fix it I would be very happy. Thanks. logs.txt

HI, I created my media gallery using Delphi 10.4.2 and it works very well. I'm migrating to Delphi 12.2 and the Gallery is having some issues. The gallery reads, and if it does not exist, creates thumbnail files of the images present on the device from the \storage\emulated\0\pictures\.thumbnails\ directory. Using API 34 when I open the file in this directory I get an access denied exception. In manifest I have these permissions: <uses-permission android:name="android.permission.ACCESS_MEDIA_LOCATION" /> <uses-permission android:name="android.permission.MANAGE_MEDIA" /> <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" android:maxSdkVersion="32" /> <uses-permission android:name="android.permission.READ_MEDIA_AUDIO" /> <uses-permission android:name="android.permission.READ_MEDIA_IMAGES" /> <uses-permission android:name="android.permission.READ_MEDIA_VIDEO" /> <uses-permission android:name="android.permission.READ_MEDIA_VISUAL_USER_SELECTED" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" android:maxSdkVersion="32" /> At runtime I check android.permission.READ_EXTERNAL_STORAGE and android.permission.WRITE_EXTERNAL_STORAGE. Now I use Nokia 2.2, Android 11 and Delphi 12.2.

Crosspost Stackoverflow Environment: Delphi 12.2 (latest SP) APP for Android and iOS Hardware Pixel 7a (Android 15) / Xiaomi Redmi (Android 12 SP1) Problem: The issue only happens on the Xiaomi device (or possibly other brands I haven’t tested). It works fine on the Pixel. In my project, I load data from an API endpoint into a local SQLite database. Then, I take photos and save them alongside the downloaded data. Here is the problematic code: procedure TPhotoForm.TakePicture(Sender: TObject); begin if TOSVersion.Check(11) then ActionTakePhotoFromCamera.Execute; end; I’m using the exact same code from the Embarcadero example: https://docwiki.embarcadero.com/CodeExamples/Athens/en/FMX.PhotoEditorDemo_Sample The issue happens after calling the procedure. The system camera opens, and I can take a picture. However, when I select the picture (to trigger the OnFinishTakingPicture event), the app crashes. There’s no error message—the app just restarts like I launched it again. Here’s the twist: this doesn’t happen every time. After a few retries (3–4 attempts), or if I restart the app, the photo-taking process works fine. Once it works, it will keep working—unless I restart the app. To reproduce the issue consistently: Uninstall the app Reinstall it Take a photo on the first run. The crash happens every time in this scenario. Investigations so far: What works The sample app from Embarcadero works perfectly on the Xiaomi device. After realizing this, I tested a few things: Access rights At first, I thought it was an issue with access rights or the Android manifest. I updated everything to match the demo project. I also discovered that you don’t actually need camera permissions when using the system camera dialog. Interesting, but it didn’t help—the issue still occurs. Bug in FMX.MediaLibrary.Android Next, I looked deeper into the code for `TAction.TakePhoto`. I traced it to `FMX.MediaLibrary.Android`. There are two key methods I investigated: - `TImageManagerAndroid.TakePhoto` - `TImageManagerAndroid.TPhotoActivityResponseListener.onResponse` `TakePhoto` passes the required data to `FActivityClient.TakePhoto(LRequestParams);`, which is implemented in a JAR file. This always works as expected—it launches the system camera dialog. The `onResponse` method is called every time the camera dialog closes, even when the app crashes. If the app crashes, first, `Application.Run` is triggered, then `TPhotoActivityResponseListener.onResponse`. But when the app crashes, `LParams.OnDidFinishTaking` is invalid because the app restarts. So everything looks fine here—no obvious issues. Energy management It feels like some kind of battery-saving issue. Maybe Android is trying to free up resources and closes my app while the camera is open. To test this, I manually installed the APK and disabled all battery optimizations for my app. The crash still happened. Log Files I also checked the ADB logs. There’s a specific message logged every time the crash occurs, but I couldn’t find any information about it online neither do I know if this is a Problem or not. Here’s a snippet from the logs: 2025.01.23 09:48:27.293 W 5929 System.err org.json.JSONException: No value for cannong 2025.01.23 09:48:27.298 W 5929 System.err at org.json.JSONObject.get(JSONObject.java:398) 2025.01.23 09:48:27.298 W 5929 System.err at org.json.JSONObject.getJSONObject(JSONObject.java:618) 2025.01.23 09:48:27.298 W 5929 System.err at android.util.MiuiMultiWindowUtils.initFreeFormResolutionArgsOfDevice(MiuiMultiWindowUtils.java:1436) 2025.01.23 09:48:27.298 W 5929 System.err at android.util.MiuiMultiWindowUtils.initFreeFormResolutionArgs(MiuiMultiWindowUtils.java:1430) 2025.01.23 09:48:27.298 W 5929 System.err at android.util.MiuiMultiWindowUtils.<clinit>(MiuiMultiWindowUtils.java:212) 2025.01.23 09:48:27.298 W 5929 System.err at com.android.internal.policy.DecorViewMultiWinStubImpl.<init>(DecorViewMultiWinStubImpl.java:19) 2025.01.23 09:48:27.298 W 5929 System.err at com.android.internal.policy.DecorViewMultiWinStubImpl$Provider.provideNewInstance(DecorViewMultiWinStubImpl$Provider.java:14) 2025.01.23 09:48:27.298 W 5929 System.err at com.android.internal.policy.DecorViewMultiWinStubImpl$Provider.provideNewInstance(DecorViewMultiWinStubImpl$Provider.java:8) 2025.01.23 09:48:27.298 W 5929 System.err at com.miui.base.MiuiStubRegistry.get(MiuiStubRegistry.java:129) 2025.01.23 09:48:27.298 W 5929 System.err at com.miui.base.MiuiStubUtil.newInstance(MiuiStubUtil.java:77) 2025.01.23 09:48:27.298 W 5929 System.err at com.android.internal.policy.DecorViewMultiWinStub.newInstance(DecorViewMultiWinStub.java:11) 2025.01.23 09:48:27.298 W 5929 System.err at com.android.internal.policy.DecorView.<init>(DecorView.java:335) 2025.01.23 09:48:27.298 W 5929 System.err at com.android.internal.policy.PhoneWindow.generateDecor(PhoneWindow.java:2380) 2025.01.23 09:48:27.298 W 5929 System.err at com.android.internal.policy.PhoneWindow.installDecor(PhoneWindow.java:2760) 2025.01.23 09:48:27.299 W 5929 System.err at com.android.internal.policy.PhoneWindow.getDecorView(PhoneWindow.java:2140) 2025.01.23 09:48:27.299 W 5929 System.err at android.view.Window.findViewById(Window.java:1516) 2025.01.23 09:48:27.299 W 5929 System.err at android.app.Activity.findViewById(Activity.java:3492) 2025.01.23 09:48:27.299 W 5929 System.err at com.embarcadero.firemonkey.keyboard.VirtualKeyboardFrameObserver.<init>(VirtualKeyboardFrameObserver.java:56) 2025.01.23 09:48:27.299 W 5929 System.err at com.embarcadero.firemonkey.keyboard.VirtualKeyboard.<init>(VirtualKeyboard.java:41) 2025.01.23 09:48:27.299 W 5929 System.err at com.embarcadero.firemonkey.FMXNativeActivity.onCreate(FMXNativeActivity.java:125) 2025.01.23 09:48:27.299 W 5929 System.err at android.app.Activity.performCreate(Activity.java:8176) 2025.01.23 09:48:27.299 W 5929 System.err at android.app.Activity.performCreate(Activity.java:8143) 2025.01.23 09:48:27.299 W 5929 System.err at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1329) 2025.01.23 09:48:27.299 W 5929 System.err at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:3752) 2025.01.23 09:48:27.299 W 5929 System.err at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:3946) 2025.01.23 09:48:27.299 W 5929 System.err at android.app.servertransaction.LaunchActivityItem.execute(LaunchActivityItem.java:106) 2025.01.23 09:48:27.299 W 5929 System.err at android.app.servertransaction.TransactionExecutor.executeCallbacks(TransactionExecutor.java:135) 2025.01.23 09:48:27.299 W 5929 System.err at android.app.servertransaction.TransactionExecutor.execute(TransactionExecutor.java:95) 2025.01.23 09:48:27.299 W 5929 System.err at android.app.ActivityThread$H.handleMessage(ActivityThread.java:2324) 2025.01.23 09:48:27.299 W 5929 System.err at android.os.Handler.dispatchMessage(Handler.java:106) 2025.01.23 09:48:27.300 W 5929 System.err at android.os.Looper.loopOnce(Looper.java:210) 2025.01.23 09:48:27.300 W 5929 System.err at android.os.Looper.loop(Looper.java:299) 2025.01.23 09:48:27.300 W 5929 System.err at android.app.ActivityThread.main(ActivityThread.java:8273) 2025.01.23 09:48:27.300 W 5929 System.err at java.lang.reflect.Method.invoke(Native Method) 2025.01.23 09:48:27.300 W 5929 System.err at com.android.internal.os.RuntimeInit$MethodAndArgsCaller.run(RuntimeInit.java:576) 2025.01.23 09:48:27.300 W 5929 System.err at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:1073) So, after all this, I’m running out of ideas on how to solve this problem. At this point, it feels like Android is terminating some background processes, which causes my app to crash. This might be happening because my app uses more RAM compared to a simple demo application like the one provided by Emba. Does anyone else have experience with this issue or any suggestions on how to move forward? Any help would be greatly appreciated. Best Regards PJM

Hi all! I'm looking for an implementation of AdMob ads under Delphi 11 on android The implementations for Delphi 10.4 and below (such as https://github.com/ersanyakit/FMX.InterstitialAd.Android, AdMobExtra...) don't work! Share if anyone has!!!

I have a situation that occurs on low-end Android devices. Short version: When the user double-taps a button, the event is being executed on the button that hasn't been created on the screen yet. What happens is, I have a list of frames created on my screen, which represent the product categories. When I tap on a category frame, the application destroys the category frames on the screen and creates a new set of product frames. The problem is, when my user double-taps very quickly on the category frame, the second click is executed on the product frame that hasn't even appeared on the screen yet. I'm using delphi 12.2 My code is something like this: procedure CreateCategory; var frm: TFrameCategory; category: TObjCategory; begin for category in listCategory do begin frm := TFrameCategory.Create(nil, category); frm.OnClick := OnClickCategory; rectangleFrames.AddObject(frm); end; end; procedure OnClickCategory(Sender: TObject); var frm: TFrameProduct; prod: TObjProduct; i: Integer; begin for i := rectangleFrames.ControlsCount - 1 downto 0 do begin rectangleFrames.Controls.DisposeOf; end; rectangleFrames.ControlCollection.Clear; for prod in listProduct do begin frm := TFrameProduct.Create(nil, prod); frm.OnClick := OnClickProduct; rectangleFrames.AddObject(frm); end; end So, the second tap is executed in OnClickProduct instead of being executed twice in OnClickCategory. How can I prevent this? i've alredy tryed a lot of things like calling this procedure on the OnClickCategory event but it doesn't seems ideal procedure disableRecTemp; begin rectangleFrames.Enabled:= False; TThread.CreateAnonymousThread(procedure begin Sleep(1500); TThread.Synchronize(nil, procedure begin rectangleFrames.Enabled := True; end); end).Start; end

Hello! I am developing an Android application using the mechanism from the demo project ForegroundLocationDemo (Delphi 12) ForegroundLocationDemo works fine, but I can't programmatically restore native activity from the background after reaching the target. Please tell me how to do it so that under a certain condition (say, when a certain location is reached) programmatically bring native activity out of the background in the procedure: procedure TLocationTrackingModule.LocationSensorLocationChanged(Sender: TObject; const OldLocation, NewLocation: TLocationCoord2D); begin FLocation := NewLocation; if FIsRunningInForeground then Begin FNotificationManager.notify(NotificationId, GetNotification); {$REGION 'My code'} If NewDistance <= Distance Then Begin StopLocationTracking; // Stopping this service turns it into only a bound service ??? // Restore native activity from background End {$ENDREGION 'My code'} End else begin if Assigned(FLocationUpdated) then FLocationUpdated(NewLocation); end; end;

Hey Delphi developers! If you've ever generated Android splash screen images using Delphi IDE and noticed they appear **stretched**, here's a simple way to fix that and ensure your splash image is always **centered without distortion**. ### Steps to Fix It: ) After building your project, go to the following paths where the splash screen files are generated: if your target android system is 64bit: <YourProjectDirectory>\Android64\Debug\<YourProjectName>\res\drawable <YourProjectDirectory>\Android64\Debug\<YourProjectName>\res\drawable-anydpi-v21 or <YourProjectDirectory>\Android\Debug\<YourProjectName>\res\drawable <YourProjectDirectory>\Android\Debug\<YourProjectName>\res\drawable-anydpi-v21 Copy both files **`splash_image_def.xml | splash_image_def-v21.xml`** from this folder and paste it into a new directory in your project (e.g., **`YourProjectDirectory\res\theme`**). 2 Open both files in Delphi IDE and add the following line inside each file: android:scaleType="centerInside" 3 Deployment: Go to Project > Deployment in Delphi IDE. Select all configurations for your target system. Click on the column header "Local Name" to sort the list by name. Scroll down, find the default splash xml files, uncheck them, and replace them with your newly edited files. Don’t forget to set the remote path for the new files according to the unchecked ones. That’s it! Clean&Rebuild and deploy your project, and you’ll see your splash image properly centered on all devices without any stretching! ------------------------------------------------------------------------------------------------- I hope Embarcadero adds this by default in an upcoming version to fix the issue. ------------------------------------------------------------------------------------------------- Hope this helps, and happy coding! If you have questions, feel free to drop them below.

Hi. I'm trying getting permission from Android in my app, i'm using standart code for this: procedure TForm1.GetPermission; begin if not PermissionsService.IsPermissionGranted(JStringToString(TJManifest_permission.JavaClass.VIBRATE)) then PermissionsService.RequestPermissions([JStringToString(TJManifest_permission.JavaClass.VIBRATE)], procedure(const APermissions: TClassicStringDynArray; const AGrantResults: TClassicPermissionStatusDynArray) begin if (Length(AGrantResults) = 1) and (AGrantResults[0] = TPermissionStatus.Granted) then ShowMessage('Access granted') else ShowMessage('Access denied'); end); end; But that not works. My app not asking permission on the launch this code, it just sending message 'Access denied'. What's wrong and how fix it? Also, when i'm using this code for getting permission WRITE_EXTERNAL_STORAGE, all working right.

I get this error when I try to run my FMX program on my android phone: Both file exists: Windows -> shlwapi.dll c:\Delphi\Delphi 11\CatalogRepository\AndroidNDK-21-22.0.48361.3236\android-ndk-r21\toolchains\aarch64-linux-android-4.9\prebuilt\windows-x86_64\aarch64-linux-android\bin\ld.exe The NDK folder is 3,508,921kB. _______ It worked yesterday. What I have changed since then, was to install a USB driver from my phone's manufacturer (OnePlus Nord): OnePlus_USB_Drivers_Setup.exe It installed this file: c:\Android\adb.exe and more in Program Files. Uninstalling the program will not delete the c:\Android\ folder.

Hello, Android has 24H/12H hour display format setting. I wanted to format my time values displayed as in system settings but I couldn't find how to read that specific is24HourFormat value. Delphi TFormatSettings does not include that information. There are earlier SO threads like this one. But that code gives me Invoke error: method not found. I also tried to import "android/icu/text/DateFormat" that I found in another SO answer and the app crashes without any error displayed. What would be the correct way to read that system setting? Thanks & Regards, Ertan

Hello, Is it possible to use a visual component with Python code for Android, for example, using the tqdm library or similar to display a progress bar along with the ProgressBar component in Delphi? Thank you.

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?

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
