[fahimeh hashemian]

Hi
I read Hello Android book and I have problem with one exercise in book.
I copied and pasted the code from book to activity_main.xml(res>layout) and strings.xml(res>values), but the error i'm seeing is Unparsed aapt error(s)!Check the console for Sudoku.

I googled and i don't answer:( I read the links of stackoverflow but my problem is not solved.

activity_main.xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/main_title" />
<Button
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/continue_label" />
<Button
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/new_game_label" />
<Button
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/about_label" />
<Button
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/exit_label" />
</LinearLayout>

strings.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="app_name">Sudoku</string>

<string name="continue_label">Continue</string>
<string name="new_game_label">New Game</string>
