Erel B4X founder Staff member Licensed User Longtime User Nov 29, 2019 #2 Might be an emulator problem as B4XView.Color works properly on real Android 10 devices. Is this an emulator created with B4A Sdk Manager? Upvote 0

E Ellen Wu Member Licensed User Nov 30, 2019 #3 Yes, the emulator was created with B4A tool. And my app doesn’t work on real Android 10 device, users told that the app crashed when first started. It only happened on Android 10. Upvote 0

Erel B4X founder Staff member Licensed User Longtime User Dec 3, 2019 #6 It is related to targetSdkVersion. Don't set it to 29 for now. It should be 28. Upvote 0
Greg Breinholt Member Licensed User Longtime User Dec 10, 2019 #8 I had the same issue. Setting to 28 removed it. Upvote 0
