This version number is not SDK version it is tools version. SDK version for supporting Android API levels is set in SDK panel in Options dialog under "SDK API level location". You can find which SDK platforms you have installed in SDK\platforms folder. Fro API 33 there should be android-33 folder inside.
I could potentially install it, but that seems to be a rather complex task. Therefore, I would like to find a way to develop applications for mobile phones using only pure Delphi and TMS Web Core. If it's possible to create a program without installing mobile support in Delphi, please direct me to a source where I should start so that I can create my first web/android application based on TMS Web Core. And how should I then run it on the specific device?
