    [font='Droid Sans', Arial, sans-serif]Working with Delphi for Android, I wanted to load my app’s icon into a TImage. Here’s the code I came up with:[/font]


    Code:
    uses
      AndroidApi.JniBridge, AndroidApi.Jni.App, AndroidApi.Jni.GraphicsContentViewText,
      FMX.Helpers.Android, FMX.Surfaces;
     
    function GetAppIcon(Dest: TBitmap): Boolean;
    var
      Activity: JActivity;
      Drawable: JDrawable;
      Bitmap: JBitmap;
      Surface: TBitmapSurface;
    begin
      Result := False;
      Activity := SharedActivity;
      Drawable := Activity.getPackageManager.getApplicationIcon(Activity.getApplicationInfo);
      Bitmap := TJBitmapDrawable.Wrap((Drawable as ILocalObject).GetObjectID).getBitmap;
      Surface := TBitmapSurface.Create;
      try
        if not JBitmapToSurface(Bitmap, Surface) then
          Exit;
        Dest.Assign(Surface);
      finally
        Surface.Free;
      end;
      Result := True;
    end;
     
    procedure TForm1.Button1Click(Sender: TObject);
    begin
      GetAppIcon(Image1.MultiResBitmap[0].Bitmap);
    end;
    



    [font='Droid Sans', Arial, sans-serif]The slightly awkward manner of casting from a JDrawable to a JBitmapDrawable in the middle is because Java type casts are not supported directly by the Delphi to Java bridge. As such, we have to get a handle to the raw Java object and re-wrap it to the desired derived class… but that’s too much of a faff all told, and the syntax will be familiar with anyone who has used the Delphi to Objective-C bridge before.[/font]
