QUESTION
Cannot create an instance of class com.comp.app.winners.WinnersViewModel
Caused by: java.lang.InstantiationException: java.lang.Class has no zero argument constructor
...ANSWER
Answered 2021-Feb-14 at 16:00You need to upgrade to Fragment 1.2.0 or higher.
As per the Lifecycle 2.2.0 release notes, the new ViewModelProvider
APIs that Hilt uses under the hood only apply when using Fragment 1.2.0 or higher. When using an older version of Fragments, those APIs are not connected to fragments and therefore your Hilt enabled ViewModel factory is not used when you use by viewModels()
.
You should upgrade to Fragment 1.2.5 (the last version of the Fragment 1.2.X set) or to Fragment 1.3.0, both of which contain the necessary API hooks to get Hilt working.

QUESTION
I have a composable with an expandable Card view.
...ANSWER
Answered 2021-Jun-12 at 03:47Cause:
This is a Behaviour Breaking API change from 1.0.0-beta07 to 1.0.0-beta08 as mentioned in release notes for Jetpack Compose.
Jetpack compose Version 1.0.0-beta08 Behavior Breaking API Change
BEHAVIOUR-BREAKING: Card now consumes clicks, making clicks added via
Card(Modifier.clickable)
to be a no-op. Please, use new experimental overload of aCard
that acceptsonClick
. (Ia8744, b/183775620)
Solution:
The solution provided is an overload of Card
which allows handling clicks alongside related properties like indication, interactionSource, enabled/disabled.
Added a new Card overload that handles clicks as well as other clickable functionality: indication, interactionSource, enabled/disabled. It wasn't possible to use a regular non-clickable Card with the Modifier.clickable because the Card will not clip the ripple indication in those cases.
Card overload:
Here is the new Card
overload which exposes onClick
as well as interactionSource
and indication
.
