Challenge 3 of 3 not working for me?

Let's inject one more view. Inject an ImageView member variable. Name it mMovieImage and again use the ID from the layout file for the ImageView.

This is what I wrote, don't know what I did wrong.

MainActivity.java

import android.os.Bundle;
import android.view.View;
import android.widget.TextView;
import android.widget.ImageView;

public class MovieActivity extends Activity {

  @InjectView(R.id.movieTitle) TextView mTitleLabel;
  @Injectview(R.id.movieImage) ImageView mMovieImage;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_movie);
        ButterKnife.inject(this);
        // The rest of the code is omitted for brevity :)
    }
}

activity_movie.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@android:color/white" >

    <TextView
        android:id="@+id/movieTitle"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textSize="32sp"
        android:text=""
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true" />

    <ImageView
        android:id="@+id/movieImage"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_above="@id/movieTitle" />

    <LinearLayout
        android:orientation="horizontal"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@id/movieTitle"
        android:layout_centerHorizontal="true"
        android:id="@+id/linearLayout">

        <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text=""
            android:id="@+id/textView"
            android:layout_weight="1"
            android:gravity="left" />

        <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text=""
            android:id="@+id/textView2"
            android:layout_weight="1"
            android:gravity="right" />

    </LinearLayout>

</RelativeLayout>

this is the error report:

/MovieActivity.java:9: error: cannot find symbol @Injectview(R.id.movieImage) ImageView mMovieImage; ^ symbol: class Injectview location: class MovieActivity 1 error

Hi,

This is a difficult to see error, but if you look closely at "InjectView" for your ImageView, you have a lower case "v" instead of an upper case "V".

Let me know if you have any more questions!

Thank you Jenyufu,you smoothened my progress.Be blessed.

import android.view.View;
import android.widget.TextView;
import android.widget.ImageView;

public class MovieActivity extends Activity {

  @InjectView(R.id.movieTitle) TextView mTitleLabel;
  @InjectView(R.id.movieImage) ImageView mMovieImage;   //<- I had forgotten to capitalize the 'V' in InjectView

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_movie);
        ButterKnife.inject(this);
        // The rest of the code is omitted for brevity :)
    }
}
