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

Question

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?

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().

@BollMose - I don't know why, but 1.1.2 just chokes to death. Probably some compatibility program that the nice people Google missed. They tend to do that a lot; welcome to Android programming! – SMBiggs Mar 14 '19 at 07:17

For me, this is should be the only acceptable answer. There's a bug consist of 1.1.2, the 1.1.3, fix this issue. – mochadwi May 20 '19 at 09:01

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 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.

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.

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!

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.

Make Sure you have added the dependency for constraint layout

}

and have made the changes to

<androidx.constraintlayout.widget.ConstraintLayout instead of

<android.support.constraint.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.

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.

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
