I created the repository here: https://github.com/bLightZP/marsGameServices

Works great!

@Rollo62 If you're referring to me, yes, everything is installed and it happens with a blank app. But there are definitely issues with upgrading over an existing version, I can list several glitches, but it's out of topic here.

I was able to debug Android application in v10.2.2, but then after installing v10.2.3 it stopped working, either the debug doesn't hook correctly (it never debugs) or it stalls on 'launching' and never continues. Pressing "cancel" at this point returns an error that the port is in use (I even read about how to change the port, but the error remained just showing a different port number). I suspect this may be related to the fact that I installed v10.2.3 ontop of v10.2.2 without doing a clean install (this resulted in a few other glitches as well).

I wrote a simple & elegant calculator for Android using Delphi Tokyo 10.2.3 and released the source code on GitHub: https://github.com/bLightZP/ElegantCalculator This sample demonstrates basic scalable Android UI, taking screen scale into account. I wrote a basic string math formula parser since I couldn't find anything free that would compile for Android. You can check out the compiled Elegant Calculator on the google play store: https://play.google.com/store/apps/details?id=com.inmatrix.ElegantCalculator

I use this code for the paths, it works for both Windows and Android UserDataPath := System.IOUtils.TPath.GetHomePath+System.IOUtils.TPath.DirectorySeparatorChar+clientName+System.IOUtils.TPath.DirectorySeparatorChar; cacheFolder := 'cache'+System.IOUtils.TPath.DirectorySeparatorChar; With regards to the UI, yes, I use high resolution source images so the same app will work on any resolution display and maintain a sharp & crisp image. Delphi does a real bad job at high quality image downscaling, but after a year of banging my head against the wall with multiple down-votes and even after offering a bounty on stackoverflow, I finally found a method that will scale the image in high quality using hardware on Android which I posted here: https://stackoverflow.com/questions/52989024/low-quality-delphi-user-interface-design-under-android-when-using-timage If you want to see how bad Delphi's GPU canvas is by default, look at this post: https://stackoverflow.com/questions/51157715/low-quality-downscale-interpolation-when-using-a-gpu-canvas-and-tcanvas-drawbitm

I actually reviewed two other formula parser, one was strictly windows and the other I thought I could convert, but after a few hours of work with it working perfectly under windows and having odd crashes under Android, I decided to just write something simple myself.

@John Kouraklis I guess it really depends on how the images are used. I use the resource approach where the images are elements in my UI (buttons, sprites, etc). Unlike windows which places all the resources in the executable, if you look into the installation folder on Android, you'll see that all the resource files are in their own folder as actual files, so the resource function is just re-routing to these files. I also use a caching mechanism in my apps where the images are scaled in high quality to the UI resolution and then saved uncompressed to speed up future loads.

When using the </> button in the text editor, it always defaults to HTML syntax highlighting. Can this be changed to Pascal by default?

Alternatively, you can store your images as resources (project / resources and images) and then use this function to load the images from the resource: procedure LoadImageFromResource(ResourceName : String; TargetBitmap : TBitmap); var rStream : TResourceStream; begin If TargetBitmap <> nil then Begin Try rStream := TResourceStream.Create(hInstance,ResourceName,RT_RCDATA); Except rStream := nil End; if rStream <> nil then Begin Try TargetBitmap.LoadFromStream(rStream); Finally rStream.Free; End; End; End; end; That way you don't care about paths.
