I have a fragment which is a child of BottomsheetDialogFragment, inside that fragment I have a google map. At first when I open this fragment using arch components NavController it works fine, than if I close this fragment and than try to open it again it crashes. This is the error log
Error inflating class fragment
Caused by: android.view.InflateException: Binary XML file line #71 in com.example.com:layout/product_location_fragment: Error inflating class fragment
Caused by: java.lang.IllegalArgumentException: Binary XML file line #71: Duplicate id 0xffffffff, tag mapFragment, or parent id 0xffffffff with another fragment for com.google.android.gms.maps.SupportMapFragment
at androidx.fragment.app.FragmentLayoutInflaterFactory.onCreateView(FragmentLayoutInflaterFactory.java:116)
Here is the fragment itself
class ProductLocationFargment : BottomSheetDialogFragment, {
override fun onCreateView(
inflater: LayoutInflater,
container: ViewGroup?,
savedInstanceState: Bundle?
): View? {
return inflater.inflate(R.layout.product_location_fragment, container, false)
}
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
super.onViewCreated(view, savedInstanceState)
//this also always returns null
val frag = childFragmentManager.findFragmentById(R.id.mapFragment) as? SupportMapFragment
}
}
and layout xml
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent">
<fragment
android:tag="mapFragment"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="0dp"
android:layout_height="match_parent"
app:layout_constraintStart_toStartOf="@id/leftGuideView"
app:layout_constraintEnd_toEndOf="@id/rightGuideView" />
</androidx.constraintlayout.widget.ConstraintLayout>
This is how I'm starting that fragment from another fragment
button.setOnClickListener {
val direction = AnotherFragmentDirections.actionAnotherFragmentToProductLocationFargment()
navController.navigate(direction)
}
Try adding the mapFragment to a FrameLayout manually instead of with <fragment
tag, but only if if(savedInstanceState == null) {
otherwise get it by tag
