Android Wear: error inflating android.support.wearable.view.WatchViewStub

Question

I get following error message when starting my Wearable demo app:

"Error inflating class android.support.wearable.view.WatchViewStub"

Exception Stack Trace:

My MainActivity:

public class MainActivity extends Activity {

    private TextView mTextView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        final WatchViewStub stub = (WatchViewStub) findViewById(R.id.watch_view_stub);
        stub.setOnLayoutInflatedListener(new WatchViewStub.OnLayoutInflatedListener() {
            @Override
            public void onLayoutInflated(WatchViewStub stub) {
                mTextView = (TextView) stub.findViewById(R.id.text);
            }
        });
    }
}

My activity_main.xml:

<?xml version="1.0" encoding="utf-8"?>
<android.support.wearable.view.WatchViewStub 
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/watch_view_stub"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:rectLayout="@layout/rect"
    app:roundLayout="@layout/round"
    tools:context="com.example.demowearapp.MainActivity"
    tools:deviceIds="wear" >
</android.support.wearable.view.WatchViewStub>

The demo project is from: Android Wear Template

I am using Eclipse Luna for this. If I directly inflate R.layout.rect, it works.

Seems you have not included the support-wearable lib project

(gradle equivalent compile 'com.google.android.support:wearable:1.1.0')

1. download library zip from here
2. unzip and create eclipse android library project
3. add library project to your existing project

unzip and try again
