  1. Hi! Android app. seems working fine in debug or release (Development) mode on my Android device. But if I upload the AAB file to Google Play Store and install it from there it exits on startup. Not sure if it's a crash I have very little experience with Android. The project is from the XE5 era. Tried: - Deleted the manifest file, so it was re-created by Delphi - Did a "Revert system files to default" - Did a "Revert to default" in Deployment Google Play Store page: https://play.google.com/store/apps/details?id=com.embarcadero.MP4StreamEditorClient As I wrote it seems working fine if I start it through Delphi+USB and also if I start it after it has been installed by Delphi, just the Install and start from Play Store does not work. Any ideas? Thank you! 3delite

    AdMob in Delphi11

    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!!!
  3. I have a customer who can't install our Android app on his Samsung Galaxy Tab A. The Play Store says the device isn't compatible with this version. I don't understand why. I owned the same tablet previously and didn't have this problem. I am using: Embarcadero® Delphi 10.4 Version 27.0.40680.4203 with Update 2. Android SDK 26.1.1 Android NDK r21e Thanks, David Carroll
  4. Hi all, A generic question. I'm deploying my apps with an embedded SQLite DB. Each time I compile/deploy, that existing on device DB file is overwritten by the default one. It's fine for development. But how do you actually proceed if you want to deploy an update? If a user has the app already with personal data, I don't want her/him to lose that data. Testing whether the DB already exists is not possible since it's deployed each time within the new binary. One way would be to have all the code to check whether the DB exists. If not, programmatically create it and fill it with sample data. If it does, just check its version and apply possible structure upgrades? But it feels like this would embark a lot of code that may not really be useful. How do you guys deploy news versions of your apps without overwriting exists DBs? I especially think about iOS and Android devices. Thanks for any light. Steve
  5. Hi all, I'm looking to distribute my android app on play store using Delphi 10.3. I know I should upgrade to Delphi 11, but trying to compile the app in the new version I'm stuck in a number of memory or compilation issues. When on Delphi 10.3 I try to start the project deployment I always get the same error "[PAClient Error] Error: E0002 Missing profile name; use paclient -? For Help". I tried to use various versions of the SDK: I tried 26, 28, 29 and even 30 but nothing. When I compile it in development mode both in debug and in release I can load it on my smartphone with Android 10, while compiling it in Release and Application Store mode I get the error mentioned. Some idea? Thanks in advance

    How to: Phone camera frame(s) to server

    Hello, I'm evaluating latest version of Delphi RAD for possible iOS/android phone application. I'd like to be able to use a phone camera (iOS and Android) to take photos (maybe 1 per second) and upload to my server. So.. 1). I found sample project "accessCameraApp" - my first question is.. would this be the component to use for my photo capture? - or should I be using something different? 2) I found internet references to indy components (I have used this in the past), but they are not installed on my component palette (no problem though I guess I can install later), but I did find TNetHTTPClient and TNetHTTPRequest, I was wondering which I should use (indy/TNetHTTPClient or maybe synapse if it is available?) for posting photo frames to my server? (i.e. a php page that saves photo(s) in database BLOB field). Any help to point me in the right direction would be great, it's more about the selection of components that I would need, I have plenty of Object Pascal experience, and I do a lot of camera work using javascript. It's just that the latest set of Delphi tools are new to me. Thanks in advance, Mike
  7. We have a few users that experience freezing and very slow response in our Android App. In Google Play Console, we get these ANR messages: The app works on 99% of the devices, so it is not a general problem, and we cannot reproduce it on our devices. What can be the reason for these problems? Another user has posted a StackOverflow question about this a year ago - but no answers: https://stackoverflow.com/questions/66657413/how-to-solve-anr-on-android-firemonkey PS. Could it be related to this warning ("Non-SDK API: Landroid/view/MotionEvent") that we also have? https://stackoverflow.com/questions/70350726/delphi-11-app-in-android-play-store-shows-warning-non-sdk-api
  8. Hi there, I was experimenting with the Android.template.xml, to use different API-related selections, to searate old and new Bluetooth settings. Some recommendations in the web point to this nice and clean solution, so separate APIs in the manifest: <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="..."> <uses-permission android:name="android.permission.BLUETOOTH" android:maxSdkVersion="30" /> <uses-permission android:name="android.permission.BLUETOOTH_ADMIN" android:maxSdkVersion="30" /> <uses-permission android:name="android.permission.BLUETOOTH_SCAN" android:usesPermissionFlags="neverForLocation" /> <uses-permission android:name="android.permission.BLUETOOTH_CONNECT" /> <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" android:maxSdkVersion="30" /> <application ... /> </manifest> Using the android:maxSdkVersion and the android:usesPermissionFlags="neverForLocation" identifier would allow an easy control over different versions. Unfortunately this didn't work in my current setup, maybe I have to rry again with a clean project, but I see a failure "attribute neverForLocation is not available". This seems that targeting to API31 is needed, and I'm still under API30, in its D11 default setup. But I'm not sure why this message pops up, and is not simply ignored, if there is an unknown attribute. Probably this needs linked somehow to the API31, and API30 throws exception. To be rescued, maybe the android:maxSdkVersion might work under different versions in different configurations, to make Delphi compatible with several API's at the same time in one manifest ? To be clear, I'm not talking about the targetSdkVersion here, but if someone could make use of the android:maxSdkVersion attribute already. I'm curious if somebody has get this working as expected under Delphi. Beside that, what would be the best way to handle BluetoothLE under API30, to be compatible with old and new devices ?

    Delphi 11: Google SignIn

    Hi All! Does anyone have a Goolge account login implementation for Delphi 11? Examples like GoogleSignin tweaked for Delphi <11 don't work!
  10. Hi, i have a multi platform app that i'm maintaining from a few time I'm getting used to debug problems, but when the app is stuck into the splashscreen and Delphi cannot even start the debug mode the problem begins. I used logcat but cannot really get any useful information. The last time i had this problem it was caused from some .so files in a wrong path and the code put into the initialization section to load those .so files was crashing my app. But this time i already fixed that and i already tried to comment out all the code into the initialization section. What can i try to understand why my app is stuck? Ide shows no errors, and this is my logcat The only error shown is "isHeavy hint type 1 for app" but i have no variable called isHeavy in my code so i really have no idea what is referring to 12-16

    Android project deployment messed up

    I have two different, very simple, cross-platform projects I'm using for development testing, one works fine, the other used to but is now getting a strange error when I try to deploy it to my Android device: The project that deploys fine has the same base project filename as the folder in which it resides. The second project (the one with the problem), DelphiVersions, is one of several projects in a folder, each project's name is appended with the type of platform it's for. The folder name is V:\DelphiVersions and I have DelphiVersionsConsole, DelphiVersionsVCL, and DelphiVersionsMobile in that folder. The last one, of course, uses FireMonkey, and is deployed to Android and iOS. I'm using Delphi 10.4 and had this working a few months ago but since Android 11 and API 30 was released I wanted to have more direct control over where and which SDK was installed and found this excellent blog that helped me get there. This also meant I switched to using OpenJDK and changed the location of the SDK and tools. Should still be good, right? As I examined the project trying to figure this out, I deleted temporary files, even removed Android support from the project and re-added it, and checked a few other things. The only thing I can think of that is different where deployment is concerned, is that the DelphiVersions one has "Mobile" appended to the end of the project name and one of the build tools must assume the project name is the same as the folder name. The obvious thing to try is rename the project to just DelphiVersions to match the folder name--I did that but it gave a similar error, this time with the path "V:\DelphiVersions\bin\DelphiVersions.apk" not found. So mismatched project name is not the source of the problem. Another thing to note is that I have projects for several versions of Delphi in sub folders and for Delphi 10.4 it's in a "104Sydney" folder and it actually generates "V:\DelphiVersions\104Sydney\DelphiVersionsMobile\bin\DelphiVersionsMobile.apk" (the file is actually where it should be!). I also looked at the deployment file list and the manifest file--still no clue. Why is the deployment process removing the first two sub-levels of folders in the filename?

    Simple app for Android 5.0.2

    Hello, I am using Delphi 10.4.2. There is a very simple app (needs internet and network status permissions, 3 pages total) that I need to run on Android 5.0.2. I compiled it with stock SDK 25.2.5 targeting Android32. When package tried to be loaded on Android 5.0.2 it says Compiler error There is a problem with the packet parsing. Docwiki says Delphi 10.4.2 supports Android 6 minimum. Even Delphi 10.3.3 supports Android 5.2 mimimum. I wonder if there is some "workaround" that I can use without installing an older version. Thanks & Regards, Ertan
  13. It can be stupid but I decided to ask. In an android application just a Delphi form and its dependencies add 30MB in the file .so of the application. Is it possible to have it as an external library and being loaded when needed? Is that possible in android and how can be done? Thank you in advance

    Notifications in android

    Hi, I want to create a Notification in an android application that shows the progress in uploading an image. I have seen many styled, multiline with icons notifications in existing applications, having also controls like a progress bar. Tried to do the same in Delphi, and I have not managed to find documentation, nor an example how to do that, without writing it in java. I found that even Flutter can now show a notification with controls inside. Can Delphi show such a notification and update its contents? Thank you in advance
  15. Delphi 10.4.2 Latest Android update has killed using S pen on edit field to bring up the virtual keyboard. Using finger or other type stylus is Ok. S pen does bring up the keyboard on other apps but not on the app compiled by Delphi. Have tried different settings on the tablet (Tab 6 Lite) but to no avail. Has anybody had the same problem and is this an Android thing or do I need to add something to my program code? Any advice would be greatly appreciated. Bill Zwirs

    [Android]How to make an event listener?

    Hello, Is there a solution with FMX to have an events listener that detects all the events that are triggered in an app? Thanks for all

    Wake up!

    Hi, I am looking for Delphi examples on waking up an application when an Android device is in sleep mode. Setting an alarm with the AlarmManager TAndroidHelper.AlarmManager.&set(TJAlarmManager.JavaClass.RTC_WAKEUP,...) fires MyAppEvent on time, it writes a message in the Memo, but the app does NOT wake up. function TfrMain.MyAppEvent(aAppEvent: TApplicationEvent; AContext: TObject): Boolean; begin result := False; case aAppEvent of TApplicationEvent.BecameActive: memo1.Lines.Add('BecameActive'); ... Only when I manually wake up the device, I see the app appear on screen. How can wake up the device when MyAppEvent notifies the event of becoming active? Even more, the app should become on the front of other running applications in the case the device is not asleep. I've searched already on the possibilities of the AlarmManager and the PowerManager, but found nothing to wake up while being asleep. Any example would be appreciated!

    Android Scroll Issue

    Delphi 10.4.2 Have used sample code provided by to send email with attachment from Android app and works fine. After I actually send email and have been returned to app I click a button to return me to the app's main menu screen (tab control) with this code TabControl1.SetActiveTabWithTransition(TabItem1,TTabTransition.Slide,TTabTransitionDirection.Reversed); but instead of returning back to main menu screen the current screen scrolls upwards and have to click button again to return to main menu screen. After this every tab control screen behaves the same way and this only happens after the send email with attachment is used. I am using the sample code from Delphi Scrollable Form Demo provided by Delphi and believe this has something to do with my problem but don't understand how. Can someone please help me with this. Thanks in advance Bill
  19. Delphi 10.4.2 Have debug parameter set to -cleaninstall in project options yet when I install to an Android device the database file (assets/internal) is not being replaced on the device. Actually, was initially but suddenly not anymore. Can anybody PLEASE point me in the right direction to solve this. Any help would be greatly appreciated Bill
  20. Delphi 10.4.2 I want to use assets/external when deploying a database file to an Android device. The device doesn't actually have any external storage (sd card) so the installation auto creates a ./external directory in the internal app directory. What is the correct way to set the database path. Documentation says to use 'TPath.Combine(TPath.GetSharedDocumentsPath,'database.db') when using assets/external yet when I use this the app cannot find the database file. Can someone please advise me as to where I am going wrong with this. Thanks in advance Bill
  21. It is a small bug but it annoys us every day: https://quality.embarcadero.com/browse/RSP-25667?jql=text ~ "versioncode" Please vote for it so it gets solved!
  22. Delphi 10.4.2 Have developed a custom app for use on Android tablet for a business. There will be approx 10 users of this app. The plan is to notify users of any update through Google Drive allowing the user to receive a link and update there tablet with latest version of the app. Especially in the early stages this may mean an updated database file (SQLite) in which case -cleaninstall is used. On testing this, if I copy .apk file direct to tablet's download directory and then navigate to that directory and double click to install......all works and db file is replaced. When testing this using Goole drive (same apk file) the app is updated but the db file is not replaced. Should I be doing something else other than '-cleaninstall' Any advice would be appreciated.

  23. This issue shows up when writing a Characteristic from the Andorid app to the BT device. Here is the sequence using these TBluetoothGattCharactertistics methods SetValueAsUint32, then 4 bytes are transmitted. SetValueAsUint64, then 8 bytes are transmitted SetValueAsUint32, then 8 bytes are transmitted, the first four bytes contain the new 32 bits and the remaining 4 bytes contain the previous 64 bit value ************************************************************************************************************* In System.Bluetooth we find this method @line 2717(10.4.2), which all of the above methods call procedure TBluetoothGattCharacteristic.SetValueAs<T>(AValue: T; Offset: Integer); var LBytes: TBytes; begin LBytes := Value; if (Length(LBytes) < Offset + SizeOf(AValue)) then SetLength(LBytes, Offset + SizeOf(AValue)); Move(AValue, LBytes[Offset], SizeOf(AValue)); SetValue(LBytes); end; LBytes is always the last value sent (64 bits or 8bytes in the above example). As long as offset is zero (0), following a 64bit value with a 32bit or less value, will always result in SetLength not being called. And as long as offset is zero, this procedure can never reduce the size of LBytes, it can only increase the size of LBytes. ***************************************************************************************************************** my work around was to create a method in my BT wrapper that creates a variable ClrValue of type TBytes set length to 1 call the method SetValue(ClrValue) This resets the TBluetoothGattCharactertistics property Value to be length 1 and thus the SetLength in the above code will always be called and the correct number of bytes will be transmitted. ***************************************************************************************************************** I went back and checked 10.1 Update2 and the same code as above is there. This may be expected behavior, I dont know, Other than my little work around, I found no intrinsic way to change the array length and thus the bytes transmitted. If you call SetValueAsUint32, I would expect 4 bytes to be transmitted, regardless of what was transmitted before.
  24. My app pop up "Access violation at address 000000001BB022128, accessing address 000030312E353820" error in iPhone. Android works perfectly without this error. This error pops up when 1. Run the app 2. Press the home button (my app still running in background) 3. Run other apps 4. Go back to my app 5. Error popup. It is quite strange that my development device iPhone 6S never shows this error. All my other testing devices, from iPhone 7 ~ iPhone X, pop this error! This error exists since XCode 11. I updated it to XCode 12.4 hope that this error can be solved, but no luck! My development environment is 1. Delphi 10.4.1 2. iOS 13.7 3. XCode 12.4 4. macOS Big Sur 5. My app uses a location sensor component and timer components to activate the location sensor when loading up the App. (I want to try it in iOS 14.4 but cannot successfully get the iOS 14 SDK add to the SDK manager. Files in Z:\Documents\Embarcadero\Studio\SDKs\iPhoneOS14.4.sdk\usr\lib are in 0 byte. I tried it from XCode 12.0 to 12.3. All failed. I think it should be a bug in Delphi IDE. Only my old iOS 13.7 SDK is still working.) Does anyone know what causes this access violation error? Please help! BR. Leo

    full screen view capture

    Hello everyone, Full screenshot. How do I capture the entire screen? In this example, I can take a screenshot of the open form. Sample; function MakeScaleScreenshot(Sender: TObject): TBitmap; var fScreenScale: Single; function GetScreenScale: Single; var ScreenService: IFMXScreenService; begin Result := 1; if TPlatformServices.Current.SupportsPlatformService(IFMXScreenService, IInterface(ScreenService)) then begin Result := ScreenService.GetScreenScale; end; end; begin fScreenScale := GetScreenScale; Result := TBitmap.Create(Round(TfmText1(Sender).Width * fScreenScale), Round(TfmText1(Sender).Height * fScreenScale)); Result.Clear(0); if Result.Canvas.BeginScene then try TfmText1(Sender).PaintTo(Result.Canvas); // Sender.PaintTo( Result.Canvas); //, RectF(0, 0, Result.Width, Result.Height)); finally Result.Canvas.EndScene; end; end; procedure TfmText1.btnScreenClick(Sender: TObject); var B: TBitmap; begin B := MakeScaleScreenshot(Self); // MakeScreenshot(Image1); Image1.Bitmap.Assign(B); B.DisposeOf; end;
