  1. Do you have a minimal reproducible example?
  2. Understood, however there will always be someone, and they may still contact support to ask why the app is not working 😉
  3. As far as I can work out, it's not possible to revoke permissions from within an application, however it is possible external to the device, using adb: https://stackoverflow.com/a/32683390/3164070 I'm not sure what the use case would be for being able to do it from within the app other than for testing purposes, and that's covered by using adb as per the link above.
  4. I've improved the experience somewhat, by opening the App Info screen instead using this code: var LIntent: JIntent; LUri: Jnet_Uri; begin LUri := TJnet_Uri.JavaClass.fromParts(StringToJString('package'), TAndroidHelper.Context.getPackageName, nil); LIntent := TJIntent.JavaClass.init(TJSettings.JavaClass.ACTION_APPLICATION_DETAILS_SETTINGS, LUri); LIntent.addFlags(TJIntent.JavaClass.FLAG_ACTIVITY_NEW_TASK); TAndroidHelper.Context.startActivity(LIntent); end; Then the user only has to: Tap "Permissions" Tap "Location" Select the appropriate option (e.g. "Allow All The Time") Use the app switcher to switch back to the app, or use the back arrow/button 3 times Still not great, but better 🙂
  5. I have code that requests location permissions at runtime, however of course the user might deny that permission. In case they made a mistake, or change their mind, I want to be able to give the user the opportunity to grant the permission because attempting to request the permission in code will result in the user not being prompted, and the permission being denied. Unfortunately, there does not seem to be an easy way (at least on Android 11) of providing this. The following code will show the Location Permissions settings for the device: var LIntent: JIntent; begin LIntent := TJIntent.JavaClass.init(TJSettings.JavaClass.ACTION_LOCATION_SOURCE_SETTINGS); TAndroidHelper.Activity.startActivityForResult(LIntent, 0); end; However the user then has to - Tap the "App access to location" item: Scroll down to the "Denied" section and tap the app in question: Then select whichever option is appropriate (for this particular app it's "Allow all the time") Then the user needs to either tap the back arrow until the settings screens disappear (Cannot use the app switcher to switch back to the app) This is obviously a horrible user experience. Does anyone know of a better way?

    TJSONObject.Format bug

    Tidy is a method of TJson (via a class helper), not TJsonObject. It's also a class method, so you don't need an instance of anything to call it

    TJSONObject.Format bug

    I used @Lars Fosdal's code: https://github.com/DelphiWorlds/Kastri/blob/672522381e8fe192f562cdcb95b9f473b08fc0b6/Core/DW.REST.Json.Helpers.pas#L77 Works better than the Format method, for me 🙂

    A form in library inside an android application

    I'd be looking at what exactly is contained in that form - perhaps some graphics (in TImage etc) that may be larger than necessary?

    Android 11 Support in 10.4.2?

    I guess I did not explain it well enough. The value you quoted is not the targetSdkVersion that I mentioned - it is the version of the installed SDK, which has absolutely nothing to do with targetSdkVersion, platform API level, or pretty much any other value that is important to Android development.

    Android 11 Support in 10.4.2?

    To clarify: Android 11 is supported. The distinction is in the value for targetSdkVersion that ends up in AndroidManifest.xml (currently, the value is set to 29, as opposed to 30). A targetSdkVersion of 30 is yet to be fully supported, as it requires changes to the support of accessing external storage (and possibly other aspects of API 30). This is what is being referred to with a statement of: They really should make the distinction if they are saying it like that. Also, targeting an API level (via targetSdkVersion) and building against an API level are 2 completely different things, so downloading platform API level 30 and changing the SDK settings to suit is not the same as changing the target.
  12. Sorry, I missed the "additional" part 🙂
  13. Please refer to this part of the answer: i.e. you would need to uncheck all of these: ..and add your own, keeping the same Remote Path and Remote Name values

    [Android]How to make an event listener?

    By "events", if you mean things like whether the app became active, entered the background etc, you can have the app subscribe to TApplicationEventMessage: http://docwiki.embarcadero.com/Libraries/Sydney/en/FMX.Platform.TApplicationEventMessage Use TMessageManager to subscribe to the event, e.g: TMessageManager.DefaultManager.SubscribeToMessage(TApplicationEventMessage, ApplicationEventMessageHandler); ..and to unsubscribe when you no longer wish to receive the messages: TMessageManager.DefaultManager.Unsubscribe(TApplicationEventMessage, ApplicationEventMessageHandler); Example handler: procedure TMyClass.ApplicationEventMessageHandler(const Sender: TObject; const M: TMessage); var LMessage: TApplicationEventMessage; begin LMessage := TApplicationEventMessage(M); case LMessage.Value.Event of TApplicationEvent.BecameActive: DoAppBecameActive; TApplicationEvent.EnteredBackground: DoAppEnteredBackground; // etc end; end;

    Can you indicate what value you have for CFBundleName? See also: https://quality.embarcadero.com/browse/RSP-32150
