Error inflating class android.fragment.app.FragmentContainerView, can someone tell me what I'm missing

Question

I'm working on getting the Google Place API to appear within a CardView.

The particular code I'm looking at is from GitHub, seems to be working for everyone else but I don't understand why it's throwing me an error.

This is the error I am getting:

The main takeaway is that there is an Error inflating class android.fragment.app.FragmentContainerView and that the issue is at line 50 of the XML.

This is the XML:

            android:layout_height="wrap_content">
        </LinearLayout>
    </LinearLayout>
</FrameLayout>

So I guess there is something wrong with the FragmentContainerView? But i'm not getting any errors in the code and nothing is coming up on Google.

I feel like maybe something is outdated rather than outright incorrect but I haven't a clue.

Thanks for any input.

You should implement new androidx.fragment dependencies to use FragmentContainerView. It is already added since version 1.2.0. You can check here

implementation "androidx.fragment:fragment:1.2.5"

For Kotlin: `implementation 'androidx.fragment:fragment-ktx:1.2.5'`. – CoolMind Nov 29 '20 at 20:40

Why does this work? You'd think Fragments are very much a part of the standard Android libs. – SMBiggs Sep 06 '21 at 14:04
@SMBiggs no, Android is moving to a model where SDK classes are provided in (static) libraries, not by the platform they run on. So there's an `android.app.Fragment` that's deprecated, and an `androidx.fragment.app.Fragment` that you should use in its place. – Jeffrey Blattman Aug 04 '23 at 16:34

This problem was created for me as well. The reason was two mistakes.

1.I did not add startDestination in nav graph .

2.I did not add @AndroidEntryPoint annotation in MainActivitey .

This error will only occur after you have added ProGuard & R8 to your project. To fix it, add the following two lines in proguard-rule.pro:

-keepnames class androidx.navigation.fragment.NavHostFragment
-keep class * extends androidx.fragment.app.Fragment{}

For me it was a typo within one of the fragments the navGraph, in the class path of the android:name attribute.. Adding a wrong path for the fragment class doesn't provide a compile time error, instead it raises android.view.InflateException...Error inflating class android.fragment.app.FragmentContainerView

So, make sure to have a correct packaging path for your fragments in android:name

<?xml version="1.0" encoding="utf-8"?>
<navigation 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:id="@+id/nav_graph.xml"
    app:startDestination="@id/mainFragment">

    <fragment
        android:id="@+id/mainFragment"
        android:name="com.example.android....MainFragment"  // <<<< This must be a correct path 
        android:label="main_fragment"
    </fragment>

</navigation>

If it is Due to Proguard Then add few lines

In proguard-rules.pro file

....
# for FragmentContainerView error
-keepnames class androidx.navigation.fragment.NavHostFragment
-keep class * extends androidx.fragment.app.Fragment{}

Your activity must be a child of FragmentActivity to use androidx.fragment.app.FragmentContainerView either you extend the FragmentActivity or the AppCompatActivity which is a child FragmentActivity class. It is recommended to extend the AppCompatActivity.

In my case, despite the same error, reason was different. However this info about adding some rules to proguard-rules.pro pointed me into the right direction. This, and some other clues in error log about problems with argument in navigation XML file. Eventually I found that it was problem with using my own classes in argument. And I don't mean the class of argument, but the fact that this class also used some of my other classes. And it was enough to add rules for each of these other classes:

-keepnames class <MyClass>

If you have done all the solutions and still the problem stands maybe you should check if your fragment constructor is empty.

if still this issue not resolved.

Please check if you your activity extending FragmentActivity or not.

suppose your activity is CustomerMapsActivity.

Need to check if CustomerMapsActivity extends FragmentActivity or not.
if CustomerMapsActivity extends BaseActivity, check BaseActivity should extends FragmentActivity.

To inflate this "android.fragment.app.FragmentContainerView" we need FragmentActivity
