Ich habe das Problem provisorisch gelöst mit untenstehendem Fix. Es scheint ein bekannter Fehler in Tokyo 10.2.2 zu sein
Zitat:
A workaround for the Android app “hang” issue with Delphi 10.2.2 Tokyo
The recent Delphi 10.2.2 Tokyo release has resulted in a flurry of reports for apps on Android that “hang” when using tab transitions, or when using “wait” animations. This article offers an explanation for the issue, as well as a potential workaround.
Update: As per E. Spelt’s suggestion on the report, I’ve modified the TThreadedTimer class to call Synchronize, rather than Queue.
TL;DR answer: You can find the workaround at the Kastri Free project.
