Good morning I have a problem to pass data between my different activities with cardview. My app could be divided as follows:
Activity A.1:
It consists of an activity with a cardview where I manage a JSON.
Activity A.2:
It is the adapter of cardview A.1 and where I get the position and the data chosen by the user and through an intent I am able to send it and collect it to activity B.1.
Activity B.1:
It consists of an activity with a cardview where I manage another JSON and until here I am able to pass the data of activity A.2.
Activity B.2:
This is the cardview adapter of B.1 and here the intent arrives empty.
Activity C:
It is where I must collect the information of the previous activities to perform the calculations. I am able to send the data of activity B.2 and collect them in activity C but the data of A.2 is lost along the way ...
I hope to have explained correctly since I am starting to program very recently and especially thanks in advance.
