Android Firebase Exception "could Not Resolve Type T"

hi have an abstract generic class 'ArticleOrdered' and a subclass 'DrinkOrdered' (see code below for class declaration). If i create a DrinkOrdered object and i save it in Firebase

Solution 1:

I had the same issue in my app, managed to fix it by casting the object myself:

DrinkOrdereda= (DrinkOrdered) dataSnapshot.getValue();

Solution 2:

I solved it by myself, using Jackson with these 2 lines of code:

ObjectMappermapper=newObjectMapper();
DrinkOrdereda= mapper.convertValue(dataSnapshot.getValue(), DrinkOrdered.class);
