Not yet. From Erel in another post.
Instructions for targetSdkVersion = 29 were added to the first post.
This will be required on August 2020 for new apps and November 2020 for updated apps.

Once it is known when API 30 is mandatory Erel will have it in hand.

No. Only around August next year. Until then it will be supported (I already ran apps with the new signature scheme).

Thanks a lot
So since november 2020 no new apps on 29?
Mine is not new so 29 is ok for me...
But just for my knowledge...

No. Since August 2020 all new apps must be 29 and from November 2020 all updates to existing apps must also be 29. Mandatory API 30 for new apps is expected around August 2021.
