I'm creating an Android app (Java) and using Navigation Components and Hilt for the first time. In the Navigation Editor I'm creating destinations and see that the fragments I created that have been annotated with @AndroidEntryPoint now show as "Hilt_" the fragment name. Now my app cannot build because the compiler is looking for a constructor with "Hilt_" the fragment name instead of just the fragment name. Ex: my fragment is named HomeFragment but in the Navigation Editor it is called Hilt_HomeFragment. Error I get when compiling:

Caused by: androidx.fragment.app.Fragment$InstantiationException: Unable to instantiate fragment com.blah.blah.fragment.Hilt_HomeFragment: could not find Fragment constructor

How should the name discrepancies be handled so I can use Hilt & navigation components together?

CodePudding user response：

"Hilt_HomeFragment" is a class generated for Hilt purposes, you should not care about it. Just make the Build -> Clean Project. Then go to your graph, clear the wrong name and write the proper one with the full package path. For example:

android:name="com.example.home.HomeFragment"

When you start typing in the name field, Android Studio will show you the prompt with matching fragments you can use - just select the proper one and the name will be filled with it.
