Error inflating class android.support.design.widget.CoordinatorLayout and ClassNotFoundException: android.support.design.R$styleable

Question

I am developing an app which have Tab with swipe functionality. I am using Eclipse to develop. I have imported the support design library as Library through Property. During run, i am keep getting this error "Error inflating class android.support.design.widget.CoordinatorLayout".

1. First i added android support design.jar and tried, which is not working
2. I added the class.jar file of support design library through Java build path which is not worked
3. Finally i imported the support design library as Library using Properties->Android->Add Library this also not working
4. I am using the Parent theme as "Theme.AppCompat.Light.DarkActionBar"

"<style name="MyMaterialTheme.Base" parent="Theme.AppCompat.Light.DarkActionBar">"

5. I am extending the AppCompatActivity, see my MainActivity.Java

   package com.example.scrollingtab.activity;

   import android.support.v7.app.AppCompatActivity;
   import android.support.v7.widget.Toolbar;
   import android.widget.Button;
   import com.example.scrollingtab.R;
   
   public class MainActivity extends AppCompatActivity implements View.OnClickListener {
   
       private Toolbar toolbar;
       private Button btnSimpleTabs, btnScrollableTabs, btnIconTextTabs, btnIconTabs, btnCustomIconTextTabs;
   
       @Override
       protected void onCreate(Bundle savedInstanceState) {
           super.onCreate(savedInstanceState);
           setContentView(R.layout.activity_main);
           toolbar = (Toolbar) findViewById(R.id.toolbar);
           setSupportActionBar(toolbar);
   
           btnSimpleTabs = (Button) findViewById(R.id.btnSimpleTabs);
   
           btnSimpleTabs.setOnClickListener(this);
   
       }

I have tried most of the things talked and provided by SO. Still i am not able to trace what is wrong in my program.

Need help to solve this.

Answer 1

I got this error while Migrating to AndroidX

To resolve I did:

1. as suggested by @Mikeumus - and added this to the module's build.gradle dependencies:

   implementation 'androidx.coordinatorlayout:coordinatorlayout:latest.version.here'

2. check in the Layout XML file (the layout that you're trying to launch with setContentView

if the Layout contains: <android.support.design.widget.CoordinatorLayout ...

replace that with : <androidx.coordinatorlayout.widget.CoordinatorLayout

3. in the same layout file - replace the closing tag

</android.support.design.widget.CoordinatorLayout>

with

</androidx.coordinatorlayout.widget.CoordinatorLayout>

Answer 2

For me, this error was resulting from using some androidx libraries but then still having the old coordinate layout in some layout.xml files.

build.gradle:

com.android.support:coordinatorlayout -> androidx.coordinatorlayout:coordinatorlayout:1.0.0-alpha1

If you're using androidx then maybe this is your problem too. I had to update the other v7 libraries like Toolbar as well.

See the androidx migration guide here: https://developer.android.com/topic/libraries/support-library/refactor
