Error inflating class androidx.constraintlayout.ConstraintLayout after migration to androidx
AndroidAndroidxAndroid Problem Overview
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?

Android Solutions
Solution 1 - Android
I solve my problem by changing all occurrences of
> androidx.constraintlayout.ConstraintLayout
to
> androidx.constraintlayout.widget.ConstraintLayout
Solution 2 - Android
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()
.
Solution 3 - Android
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
Solution 4 - Android
build.gradle => check dependencies version
implementation 'androidx.constraintlayout:constraintlayout:1.1.1'
to change
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
solved the problem
Solution 5 - Android
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.
Solution 6 - Android
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.
Solution 7 - Android
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!
Solution 8 - Android
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.
Solution 9 - Android
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
Solution 10 - Android
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.
Solution 11 - Android
Make sure to change to
<androidx.constraintlayout.widget.ConstraintLayout
instead of
<android.support.constraint.ConstraintLayout
and
<androidx.constraintlayout.widget.Barrier
instead of
<android.support.constraint.Barrier
Solution 12 - Android
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.
Solution 13 - Android
Since my implementation was already androidx.constraintlayout.ConstraintLayout
, just using a Clean Project solved my problem.
Solution 14 - Android
yepp. mavenCentral() and correct dependencies solve my same problems
Solution 15 - Android
I had a similar error.

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.
Solution 16 - Android
I updated the dependency, yet it did not resolve the error. Then I did a clean project and build and it is working now.
Solution 17 - Android
- 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.
Solution 18 - Android
change your constraint layout dependancy to implementation 'androidx.constraintlayout:constraintlayout:2.0.2'
Solution 19 - Android
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"
Solution 20 - Android
I had the issue with ImageFilterView converting jpg images to png solved the issue for me.
