Async loading

[N7Nico]

Hi, I'm opening this issue because I saw the previous issues about dynamically load events, but I can't make it functional... I tested all the methods posted and it goes into an infinite loop or don't display anything.

In my async task I fill a database with the asked month (provided by an API) and I add events to a private list in my class and finally return them, but several threads try to add events since onMonthChange is called 3 times and I can't figure it out how I can block the other threads or use local variables only...

Actually I wait for the answer of the API : it's functional but the UI is blocked and it's not dynamic...

Can you help me about this ?

Regards, Nicolas

PS: By the way i'm using AndroidAnnotations
