    I'm trying to generate a custom classes.dex file for our android app because I need to include a specific .jar-file

    What is the jar file, and is there some reason why just adding the jar to the project is not sufficient?

    However it is never overwritten

    Overwrite can be somewhat misleading. It refers to what happens when the file is deployed from the local file to the application package, not whether the file is overwritten when the app starts - this process occurs in the System.StartUpCopy unit (in the rtl\common folder of the Delphi source), and as evidenced by line 83 (at least in Delphi 12.1): 

      if not FileExists(DestFileName) then //do not overwrite files

    ..when the files are put in their final destination, if the file exists it is not overwritten. A couple of possible workarounds:

     

    1. Patch the System.StartUpCopy unit so that it does overwrite 


    2. Use files with "versioned" filenames, e.g. fudley-1.0.0.db, and replace the entry in the deployment with the new version. In your apps startup code, look for files using pattern matching, e.g: 

    uses
  System.IOUtils;

procedure TForm1.FormCreate(Sender: TObject);
var
  LDBFiles: TArray<string>;
begin
  LDBFiles := TDirectory.GetFiles(TPath.GetDocumentsPath, 'fudley-*.db', TSearchOption.soTopDirectoryOnly);
  // If there's only ever one file, it should be the value in LDBFiles[0], so rename that to fudley.db 
end;

    Took me a while to get past all the Ios island travel tips before finding this: https://developer.apple.com/design/human-interface-guidelines/live-activities

    Same thing happened to me re Ios Island 🙂

     

    Following the live activities link leads to: https://developer.apple.com/documentation/ActivityKit/displaying-live-data-with-live-activities

     

    Which talks about using Widget Extensions, which are yet to be possible in Delphi, however there's a slim chance that the extension can "talk" to Delphi code: https://blog.grijjy.com/2018/11/15/ios-and-macos-app-extensions-with-delphi/

     

    I have very little optimism about the possibility

    I don't even have sdk 32 installed!

    targetSdkVersion refers to the highest API level that your app can target, not which API level in your SDK that you built against. If Play Store says your app targets API level 32, check AndroidManifest.xml in the project output folder for which you built the app for Play Store. You may just need to do a clean and rebuild to ensure that AndroidManifest.xml is updated.

    The ExoPlayer in its old form is deprecated, does this Alcinoe library also works in the new Media3-Version?

    No - the Alcinoe implementation is based on the old ExoPlayer (in the com.google.android.exoplayer2 namespace). I am working on an implementation that uses Media3, but only just today have experimental code working that plays a video from a nominated URI.

    How to browse for image files on the users android phone.

     

    Is this possible without using intents?

    Browsing outside of the application itself requires intents.

    If not, is there a library which can be used for this?

    You could use Kastri, which has this Files Selector demo.

    Tools > Getit Package Manager gets me the Getit Package Manager window. Then what?

    This is GetIt Package Manager configured to show what patches/hotfixes are available, and an arrow pointing to what to select to show whether updates are available:

    I create a blank app in Android with only a button and the splash screen disabled

    I'm curious as to what settings you changed to disable the splash screen. I can't work it out - I unchecked "Include Splash Images" but it still shows the splash. I guess there's more to it than that?

    I'm looking at extracting compiler options from .dproj files, and looked for an existing "map" of options to PropertyGroup entries, but came up blank, so I figured I'd create one. I'm hoping that others could help verify what I've come up with as well as fill in some blanks. The following was created from the output of the help from dcc32, and from looking through the DCCStrs unit for what appears to match. The value from DCCStrs is on the line following each option. The numbers after some of the DCCStrs value are what also appear in the DCCStrs source. Those I couldn't match are signified with: ??? 

    Compiler Options:

-A<unit>=<alias> = Set unit alias

    Is TFrame problem free?

    The biggest problem is when you create descendant forms (i.e. at design-time) where the ancestor contains frames. Otherwise, for me they're totally fine.

    When I read the documentation and different tutorials and forum posts this seems to be easyly done:

    Which forum posts, and which tutorials?

    Notification.SoundName:= MySoundfile;

    Sounds on Android are no longer associated with the notification itself, rather they are now associated with the channel via the SoundName property.

     

    Note that you need to add the mp3 file to the deployment using a RemotePath of res\raw, and use the filename without the extension for the SoundName on the channel, e.g. for mysound.mp3, use a value of mysound for SoundName.

     

    On iOS, you need to deploy the sound file with a RemotePath of .\, and use the actual filename for SoundName on the notification (i.e. not the channel)

    This work fine in Windows OS, but in macOS second synchronisation don't works (Labels remains empty).

    Looks like a bug - In the TPlatformCocoa.ShowWindowModal method in FMX.Platform.Mac, it never calls CheckSynchronize inside of the loop.

     

    In Delphi 12, modifying FMX.Platform.Mac.pas starting at line 4855: 

          while True do
      begin
        CheckSynchronize; // <--- Add this line

    Fixes it.
