Project upgrade to 5.6 results in Android touch events not working.

Am in process of sanity checking upgrading an old test project, and packaging a blank test, but decided this is critical enough to warrant an immediate Question.

From a facebook post : " I had to delete all the config files and rebuild them, and now it’s working again." - Hmmm https://www.facebook.com/groups/uedevs/posts/2900599046807941

Tried out a small test project, no problem there. Investigations continue… Perhaps something changed in the PlayerController? Or Enhanced Input?

Thanks for bringing this to our attention. A source fix is available at https://github.com/EpicGames/UnrealEngine/commit/becac1d213e962d9887dc585ab86b79a7089cd6f.

Best regards.

5.5 to 5.6 ( source forks )

  • I am sanity checking with a EGS vanilla 5.6 upgrade next week
  • A more minimal testproject upgraded successfully ( just a level + ui buttons )
  • I have diffed android specific config files on the engine, but seen nothing suspicious

Enabling Bluetooth controllers seems to be a workaround fix. This setting is on by default in 5.6.1 BaseEngine.ini, and was false in our configs.

bAllowControllers=True

A friendly fellow in the discord has a source fix : https://github.com/EpicGames/UnrealEngine/commit/59a8c382ccc65f7503865d6aed2463a262a367bb
