Error inflating class androidx.constraintlayout.ConstraintLayout after migration to androidx

I just made a migration to androidx through Android Studio menu option Refactor -> Refactor to AndroidX

I'm getting the following error:

android.view.InflateException: Binary XML file line #2: Binary XML file line #2: Error inflating class androidx.constraintlayout.ConstraintLayout

Any idea?

In my case, the issue was resolved by correctly setting the colors in the application. We carefully monitor the API version in each color used and simply change the color in case of a version higher than the minimum allowed. In the attributes, select Pick a Resource of the color that you want to check and pay attention here: check API version

None of the solution worked for me, looking closely at the exception stack trace:

 Caused by: android.content.res.Resources$NotFoundException: Resource "com.XXX.XXX:drawable/walpaper" (7f0800aa)  is not a Drawable (color or path): TypedValue{t=0x1/d=0x7f0800aa a=-1 r=0x7f0800aa}

drawable background image loading was causing some issue on my old test device (newer devices load it just fine). Just removed the following line from my layouts it is working fine now, need to figure out how to set the background now..

 android:background="@drawable/walpaper"

Since my implementation was already androidx.constraintlayout.ConstraintLayout, just using a Clean Project solved my problem.

I had this issue with Android Studio 4.0. I used android studio 4.0 for a couple of days without problems. Seemingly out of nowhere the designer view stopped working. I could only fix this by uninstalling android studio and installing the newest android studio version.

Make Sure you have added the dependency for constraint layout

 dependencies  {
    implementation "androidx.constraintlayout:constraintlayout:1.1.3"
}

and have made the changes to

<androidx.constraintlayout.widget.ConstraintLayout instead of

<android.support.constraint.ConstraintLayout

Add androidx.constraintlayout.widget.ConstraintLayout to the dependencies:

dependencies  {
    // https://mvnrepository.com/artifact/androidx.constraintlayout/constraintlayout
    implementation "androidx.constraintlayout:constraintlayout:1.1.3"
}

It's available on mavenCentral().

make sure your project migrate to androidx completely , In my case I found :

<android.support.constraint.ConstraintLayout

instead of

  <androidx.constraintlayout.widget.ConstraintLayout

So change it and my problem fixed!

Find all default before to click Refactor -> Refactor to AndroidX
Open this https://developer.android.com/jetpack/androidx/migrate/class-mappings and find "android.support.v4.widget.DrawerLayout". In same line AndroidX class name is "androidx.drawerlayout.widget.DrawerLayout" copy it.

Replace all "android.support.v4.widget.DrawerLayout" to "androidx.drawerlayout.widget.DrawerLayout" in your project"s code, layout and menu. After all replace it will work.

I mean find mapping and use it in whole project.

I had the same problem, I resolved it as follows:

In your dependecies if you have added

implementation 'androidx.constraintlayout:constraintlayout:1.x.x' that is correct

but in your xml layout file you have to use the widget as

androidx.constraintlayout.widget.ConstraintLayout

I copied and pasted an existing ConstraintLayout tag from the xml, which was causing the issue for me. Simply deleting, and re-adding the ConstraintLayout tags in AndroidStudio from scratch fixed the issue for me.

After clicking on Refactor -> Migrate to AndroidX , Make sure your all dependencies in the build.gradle(Module:app) is marked to the newest version.

If its not, dependency will appear in yellow highlighted color and you can change it by hovering the mouse over it.

Secondly, Change the ConstraintLayout tag in all XML layout files to

androidx.constraintlayout.widget.ConstraintLayout

For more safer option, clean your project and sync it again after the above steps.

I has same issue after:

migration support library to androidx;
increment targetSdkVesrsion to 29;

I also use:

implementation "uk.co.chrisjenx:calligraphy:2.3.0"

I tried all posts from this question, but none success.

I fix it by adding one string .disableCustomViewInflation() to Calligraphy init:

@Override
public void onCreate() {

    super.onCreate();
    // ...
    CalligraphyConfig.initDefault(new CalligraphyConfig.Builder()
            .setDefaultFontPath("fonts/Sans-Regular.ttf")
            .setFontAttrId(R.attr.fontPath)
            .disableCustomViewInflation() // <----- this fix
            .build());
    // ...
}

I hope next release of Calligraphy (Christopher Jenkins thanks for your great job) will fix it inside too.

I updated the dependency, yet it did not resolve the error. Then I did a clean project and build and it is working now.

Following the recomendations:

add androidx.constraintlayout.ConstraintLayout to the dependencies:

dependencies  {
    implementation "androidx.constraintlayout:constraintlayout:1.1.3"
}

And the repository mavenCentral().

Works for me. I could compile the APK.

If after adding mavenCentral() as a repository in your Gradle file and changing androidx.constraintlayout.ConstraintLayout to androidx.constraintlayout.widget.ConstraintLayout didn't solve your problem then try doing Invalidate cache and restart from the file menu. It worked for me.
