android.view.InflateException: Error inflating class android.support.design.widget.CoordinatorLayout

Question

I would like to show a SnackBar and a FloatingActionButton so I added android-support-design.jar to my project. But I got the following error:

My Activity is:

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        findViewById(R.id.fab).setOnClickListener(new View.OnClickListener() {
              @Override
              public void onClick(View view) {
                Snackbar.make(view, "Snackbar", Snackbar.LENGTH_LONG).show();
              }
            });

    }
}

activity_main.xml:

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <android.support.design.widget.FloatingActionButton
        android:id="@+id/fab"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="end|bottom"/>

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

styles.xml:

<resources>
    <style name="AppBaseTheme" parent="Theme.AppCompat.Light">

    </style>

    <style name="AppTheme" parent="AppBaseTheme">

    </style>

</resources>

I found some similar problems but none of the solutions worked for me. Anyone can help me about this? Thank you very much.

@Logic Thank you for answering. I'm sorry but I don't really know which file should contain this line. Can you tell me a file name or maybe a path? (I'm using Eclipese) — Mátyás Kiglics, Jan 08 '16 at 16:39

Change the target of design library to 23
Import support design library from \sdk\extras\android\support\design to eclipse workspace.
Open project.properties of AppCompat and design Library and target it to 23
Clean complete workspace
Run

Hope it helps
