After I upgrade Gradle version upto 8.0, I encounter "constant expression required" error.
This is because AGP 8.0 doesn't allow reference to resourceID.
In my case, I use below code:
switch(view.id) {
case sample1:
case sample2:
......
}
Solution1:
Change switch statement to if-else statement
Solution2:
Add below properties to gradle.properties file
android.nonFinalResIds = false
android { buildFeatures {
buildConfig = true
} }
Put on above code into build.gradle file (app level).
This is because AGP 8.0 sets the default value of android.defaults.buildfeatures.buildconfig to false.

Solution :
Initialize ViewPagerAdapter in onCreateView.
Wrong Example:
class MainFragment : BaseFragment<FragmentMainBinding>() {
private val viewPagerAdapter : ViewPagerAdapter by lazy { ExampleViewPagerAdapter(this) }
}
