Android Question Android 12 - are we ready ?

Android 12 is now almost among us From the point of view of the B4X development environments, what changes?

You can see the behavioral changes here: https://developer.android.com/about/versions/12/behavior-changes-all

Setting targetSdkVersion to 31 will apply more restrictions, however it will only be relevant around August 2022.

wes58 in this post: https://www.b4x.com/android/forum/t...e-startserviceat-in-a-loop.130989/post-824649 suggests that Android 12 will negatively impact Android Alarm Manager and therefor StartServiceAt

I received a report from a user that GPS is not working in Android 12. My app works fine in all other versions, but I didn't have the chance to personally test it on Android 12.

My Pixel 4a just got updated to 12 and I hate the new UI and its limited control of colour - either one of four strange colours or an even worse one selected somehow from your wallpaper. Luckily I don't usually see it apart from settings as I use a third party launcher. The notification panel is a full screen space wasting mess though and that's unavoidable

I've found no functionality problems so far. GPS is fine.

For me this is most annoying feature:

Android 12 changes the default handling of the system Back press on launcher activities that are at the root of their tasks. In previous versions, the system would finish these activities on Back press. In Android 12, the system now moves the activity and its task to the background instead of finishing the activity. The new behavior matches the current behavior when navigating out of an app using the Home button or gesture.

The notification panel is a full screen space wasting mess ...

I think that it is worse than that. Many of the button captions do not even fit into the buttons, and this is on a Pixel 4a - Android's own 'phone! How those iPhone owners must be laughing now.

How can we get the Android design team to join this forum where they can get some proper guidance?

I hate the new UI

Agreed, I'm not a fan. Surprised they launched this, feels very poorly designed overall. Big step backwards from 11.

For me this is most annoying feature:

I actually think that it makes sense. This is also the default behavior of B4XPages projects.

Most users don't try to understand the subtle difference between the two cases.
